Sea Hares Scrub Seagrass by the Seashore | Deep Look

Teacher or professor: Deep Look
Subject: Biology
Content of the Lesson: These sea slugs may look like lazy, zebra-striped spoonfuls of jello, but eelgrass sea hares are actually environmental heroes. Their voracious appetite for algae helps keep underwater meadow ecosystems in balance–which is great news for sea otters.

See the unseen at the very edge of our visible world. Explore big scientific mysteries by going incredibly small. --- Eelgrass sea hares are tiny aquatic slugs named for the bunny-like tentacles on top of their head. They can be found munching on the microscopic algae that grow on the surface of eelgrass, a type of marine seagrass. Also known as the Taylor’s sea hare, these humble, zebra-striped slices of green jello are actually crucial to the health of their ecosystem. They don’t eat the grass itself; instead they help the meadows grow by clearing the way for sunlight to reach the plants, scraping the blades of grass clean with their rows of tiny teeth. The seagrass, in turn, serves as a safe haven to lay their eggs, and protection from predators like crabs and fish. The blades of grass also protect more than just these voracious little cleaners. At Elkhorn Slough, a large winding estuary off of Monterey Bay, the eelgrass beds form a habitat for a diverse community of animals and plant life, which includes sea otters, Dungeness crabs, clams, skeleton shrimp and various fish. For decades, nutrient overload from agricultural runoff has caused excessive algae blooms in Elkhorn Slough, as the thick algal mats block out the sunlight needed for the grass to grow. But with the reintroduction of sea otters to Elkhorn Slough in the 1980’s, ecologists observed a balancing effect on the system. The otters started eating the crabs that eat the sea hares. Because of this trophic cascade, the slug population grew, and their appetite for algae helped keep the eelgrass clean, counterbalancing the effects of the algal blooms. --- Is a sea hare a nudibranch? Nudibranchs and sea hares are both different types of sea slugs. There are various species of nudibranchs and sea hares. All sea slugs are a kind of mollusk. --- What is a trophic cascade? A trophic cascade occurs when the addition or removal of a top predator has a dramatic effect on the food web, drastically changing the structure of an ecosystem, and how nutrients cycle through it. ---+ Read the entire article on KQED Science: https://www.kqed.org/science/1970711/sea-hares-scrub-seagrass-by-the-seashore/ ---+ For more information: Paper on the ecological effects of sea otters, and their relationship to eelgrass and sea hares, by Brent Hughes, Sonoma State University - https://www.pnas.org/content/110/38/15313 Katharyn Boyer’s Lab at San Francisco State’s Estuary and Ocean Science Center, focusing on eelgrass ecology and restoration work in the San Francisco Bay http://online.sfsu.edu/katboyer/Boyer_Lab/Home.html ---+ Thank you to our Top Patreon Supporters ($10+ per month)!

Learn more at: http://www.pbs.org/wnet/peril-and-promise/ If you’re in the United States and you turn on the TV, accidentally open twitter, or start to read a newspaper app, chances are you’ll see a bunch of people talking about the upcoming federal election. But what you might not see much of - coverage of the local elections where you live. Let alone, information about those policy makers’ climate ideas. Which is frustrating because, I’m going to let you in on a little secret now: a lot of climate policy happens at the state and local level. Compared to the federal government, local and state lawmakers are typically more efficient - they get more done in less time. They’re often easier to get in contact with and just physically closer than your federal lawmakers working in DC. Plus, local laws tend to have a lot more direct impact on your life and how your community responds to the climate crisis. For example, a lot of your local tax money probably goes to fund education. Your locally elected school board is in charge of how that funding is used, and they get to decide if your local school district buys electric busses, or adds a climate change section to the curriculum. But why is that? Why is your local government so much better set up for implementing climate solutions than the federal government?

Starfish Gallop With Hundreds of Tubular Feet | Deep Look

Teacher or professor: Deep Look
Subject: Biology
Content of the Lesson: They may look cute and colorful, but starfish are actually voracious predators. To sniff out and capture their prey, they rely on hundreds of water-propelled tube feet, each with a fiercely independent streak. Watch the new PBS Terra science show, OVERVIEW: https://youtu.be/Lt9qYvKFumM SUBSCRIBE to Deep Look! http://goo.gl/8NwXqt DEEP LOOK is a ultra-HD (4K) short video series created by KQED San Francisco and presented by PBS Digital Studios. See the unseen at the very edge of our visible world. Explore big scientific mysteries by going incredibly small. --- On a visit to a friend’s lab in Tokyo, marine biologists Amy Johnson and Olaf Ellers witnessed something they’d never seen before. The starfish in Tatsuo Motokawa’s lab weren’t content slowly gliding across the floor of their tank, they bounced and galloped, zooming around their enclosure. For one of the most familiar animals in the sea, this was a new behavior, never before described in the scientific literature. “It was an absolute epiphany,” said Johnson who studies how sea stars move and teaches marine biology along with Ellers at Bowdoin college in Maine. “ That moment we first saw them bounce completely transformed everything we were planning to do with our research.” Since then, Johnson and Ellers have worked to change the way we understand these animals who have successfully made a home on this planet for at least 450 million years. --- What do starfish eat? Most sea stars are predators. They hunt a variety of marine animals including bivalves like mussels and clams but also sponges, snails, algae. Some sea stars are scavengers that consume detritus. How do starfish breathe? Sea stars mostly transpire through their tube feet which have very thin walls. Oxygenated water travels to other parts of the starfish’s body through its water vascular system. Do all starfish have five arms? Nope! There are many types of sea stars and while most have five arms there are stars with fewer or more. Sea stars have radial symmetry, but may have evolved from a bilateral ancestor (with right and left sides). ---+ Read the entire article on KQED Science: https://www.kqed.org/science/1970271/starfish-gallop-with-hundreds-of-tubular-feet/ ---+ For more information: Article: Sea star inspired crawling and bouncing https://royalsocietypublishing.org/doi/10.1098/rsif.2019.0700 ---+ More Great Deep Look episodes: Sea Urchins Pull Themselves Inside Out to be Reborn | Deep Look https://www.youtube.com/watch?v=ak2xqH5h0YY&t=44s A Sand Dollar's Breakfast is Totally Metal | Deep Look https://www.youtube.com/watch?v=dxZdBPDNiF4 Decorator Crabs Make High Fashion at Low Tide | Deep Look https://www.youtube.com/watch?v=OwQcv7TyX04 For Pacific Mole Crabs It's Dig or Die | Deep Look https://www.youtube.com/watch?v=tfoYD8pAsMw ---+ Shoutout! 🏆Congratulations🏆 to the following fans on our Deep Look Community Tab for being the first five to ID both names for the water inlet structure on a starfish - the sieve plate or madreporite!

Raising Peregrine Falcon Chicks is a Real Cliff-hanger | Deep Look

Teacher or professor: Deep Look
Subject: Biology
Content of the Lesson: High up in their 300-foot tower penthouse, falcon stars Annie and Grinnell's romance quickly gets real, as they face the tough realities of raising a family. They furiously guard their eggs from invaders, then stuff their screaming newborn chicks with meat. Will these kids ever leave the nest?

See the unseen at the very edge of our visible world. Explore big scientific mysteries by going incredibly small. --- Grinnell, a male peregrine falcon, looked up from his nest and started screaming. It was late March and he was taking a turn warming the four eggs he and his partner, Annie, were caring for in their home atop the bell tower at the University of California, Berkeley. A young female peregrine falcon, quite a bit larger than Grinnell, was lurking on the ledge above him. Young peregrine falcons will often come around the site where a pair is already nesting to check it out and plot a possible takeover. She walked right up to Grinnell in the nest and shrieked almost in his face. Grinnell spread his wings wide and swiftly chased her off the tower. Grinnell had reason to be territorial. He and Annie have been raising chicks on this 300-foot tower since 2017. Peregrine falcons are the fastest animals in the world: When in hot pursuit of a pigeon or other bird to pluck from midair they can reach 240 miles per hour – faster than a single engine plane. But even these raptor superstars need to settle down with a mate and have some babies to whom they can pass on their love for meat. When they do, they often pick a tall building in a city. Peregrine falcons regularly make their homes in cities across the United States, from New York to Chicago to San Francisco. --- --- Why do peregrine falcons nest on tall buildings? Tall buildings – just like the cliffs they live on in the wild – give peregrine falcons protection from predators, a perch from which to hunt pigeons and other birds and ledges where they can lay their eggs. --- Do peregrine falcons make nests? Peregrines don’t build a nest of twigs and leaves. In the wild, they lay their eggs on a ledge in a cliff into which the female has scratched a bowl-shaped depression called a scrape to prevent her eggs from rolling away. --- Why did the peregrine falcon nearly go extinct? The pesticide DDT, used heavily in the 1940s and until 1972 in the United States to control mosquitoes and agricultural pests, accumulated in peregrines’ bodies. It thwarted the development of their embryos. And it reduced the amount of calcium in the eggs, which resulted in eggshells so thin that they broke when parents sat on them. ---+ Read the entire article on KQED Science: https://www.kqed.org/science/1969983/raising-peregrine-falcon-chicks-is-a-real-cliff-hanger/ ---+ For more information: Watch Annie and Grinnell live on three cameras on the Cal Falcons channel: https://www.youtube.com/channel/UCmjo8Rlp6q98TZlG8TDF4GQ/featured ---+ Thank you to our Top Patreon Supporters ($10+ per month)!

Is a Spider's Web a Part of Its Mind? | Deep Look

Teacher or professor: Deep Look
Subject: Biology
Content of the Lesson: Orb weaver spiders build exquisite spiral webs not only to catch insects, but to extend their senses. Once they shrink-wrap their prey with silk, the nearly blind spiders can store them for later, and read their web's strands as a kind of memory map to guide them back. Take the PBS Digital Studios Survey! http://to.pbs.org/2020survey SUBSCRIBE to Deep Look: http://goo.gl/8NwXqt DEEP LOOK is an ultra-HD (4K) wildlife and nature series created by KQED San Francisco and presented by PBS Digital Studios. See the unseen at the very edge of our visible world. Explore big scientific mysteries by going incredibly small. --- The more than 48,000 spider species create a wide variety of web styles. There are over 4,000 different species of orb weaver spiders alone; these are the eight-legged spinners that create the famous spiral-shaped webs. Anyone who’s watched orb weavers in action has seen them use their exquisite creations to deftly ensnare flying insects. Impressive as this, the webs function as much more than deadly traps. Webs play an integral role in everything an orb weaver does. When spiders are hungry, they can tighten the web’s strands and even adjust its size and shape, depending on what size of prey they’re in the mood for. These species are only able to see light, dark and a little movement, but they are somehow able to quickly navigate their webs, pinpointing their unlucky victims and binding them in silk, a meal saved for later. Because they can do so much with such tiny brains, some researchers think orb weavers use their webs as a form of extended cognition, outsourcing advanced mental tasks like problem-solving and memory. For example, once they have killed and wrapped their prey, a spider can store it for later, then easily find it again. They don’t need to remember every single thread they have spun — just a few previous steps. By using their webs to do some of their thinking for them, orb weavers may be preserving precious brain power for other necessary and complex tasks like capturing prey. --- Where do orb weavers spiders live? Orb weaver species live everywhere on planet earth except for Antarctica and the Arctic. As long as there is abundant food (i.e. insects) and a place to build their web, you are likely to find an orb weaver. --- What other kinds of spider webs are there besides orb webs? In addition to the signature spiral-shaped designs made by orb weavers, spider webs come in various other styles, such as tangles (aka cobwebs), funnels and sheets. ---+ Read the entire article on KQED Science: https://www.kqed.org/science/1969661/is-a-spiders-web-a-part-of-its-mind/ ---+ For more information: The work of Thomas Hesselberg http://www.thomashesselberg.com/ Hilton Japyassú’s work on extended cognition in spiders https://link.springer.com/article/10.1007/s10071-017-1069-7 ---+ Shoutout! 🏆Congratulations🏆 to the following fans on our Deep Look Community Tab for being the top five emjoi and ascii artists for this episode!

This is NOT a Dandelion. | Deep Look

Teacher or professor: Deep Look
Subject: Biology
Content of the Lesson: Not every yellow bloom ― or fluffy white globe ― taking over your backyard is a dandelion. Some of them are close relatives called catsears. But both of them have a little secret. To tell them apart and discover why they’re so successful you need to peek under their petals. Take the PBS Digital Studios Survey: http://to.pbs.org/2020survey SUBSCRIBE to Deep Look! http://goo.gl/8NwXqt DEEP LOOK is an ultra-HD (4K) short video series created by KQED San Francisco and presented by PBS Digital Studios. See the unseen at the very edge of our visible world. Explore big scientific mysteries by going incredibly small. --- Gardeners cursing as they yank out yellow blooms from the ground might be misplacing their anger. Not everything that looks like a dandelion is one. Dandelions have many doppelgangers, among them the most successful plant you’ve never heard of: catsears. Bees and butterflies love the nectar and pollen provided by dandelions and catsears, and little songbirds like lesser goldfinches feed on their seeds. But it’s hard to convince some gardeners of their virtues. “Most people who have a nice turf want only grasses,” said Joe DiTomaso, a weed researcher who retired from the University of California, Davis. Whether you’re a friend or a foe, telling dandelions and catsears apart could be useful ― if only to know thine enemy ― and a fun way to ponder what makes these yellow blooms so successful. --- How do you tell if it’s a dandelion? Under a dandelion’s ― and a catsear’s ― petals you’ll see green structures that hold the bloom. They’re called phyllaries. In catsears, they all point up. In dandelions, some phyllaries curl down. Dandelion and common catsear leaves have a similar shape, with toothed edges that give dandelions their name ― an adaptation from the French dent-de-lion, or lion’s tooth. The leaves of the common catsear are more lobed than pointy and they’re furry, while dandelions’ are smooth. Both leaves are edible, prepared in salads or sautéed. One other way to tell them apart is that each stem of catsears branches into multiple blooms, while dandelions have only one bloom per stem. -- What other plants look like dandelions? A plant by the scientific name of Leontodon resembles dandelions so much that it is known as false dandelion. It is also known as lesser hawkbit, said DiTomaso. “Where it’s confusing is its leaves look fairly similar and it has one flower per stem like dandelion, so a lot of people think it’s dandelion,” he said. ---+ Read the entire article on KQED Science: https://www.kqed.org/science/1969214/this-is-not-a-dandelion ---+ More Great Deep Look episodes: Watch This Bee Build Her Bee-jeweled Nest https://youtu.be/oPbH1YhsdP8 Why Do Tumbleweeds Tumble? https://youtu.be/dATZsuPdOnM ---+ Shoutout! 🏆Congratulations🏆 to the following fans on our Deep Look Community Tab for being the first five to correctly explain which flower was a dandelion and which was a catsear!

What Actually Makes Water Roll Off a Duck's Back? | Deep Look

Teacher or professor: Deep Look
Subject: Biology

Ducks, geese, and many other species of aquatic birds come to California to breed, build nests and raise broods. If you go to your local pond right now, chances are good that you will see a mallard or Canada goose paddling along with a gaggle of its offspring in tow. But watch for too long and you might find yourself wondering “how do these birds stay warm and dry in the water?” It’s a question that Jack Dumbacher, curator of ornithology and mammalogy at the California Academy of Sciences in San Francisco has been asked many times. The secret to waterproof waterfowl, it turns out, lies in their feathers. “Aquatic bird feathers are really different than those of other birds,” Dumbacher said. --- What do ducks eat? Ducks eat a lot of different things, from snails and tadpoles to grass and fruit. Some ducks specialize in a certain food like fish, while others are more general in their appetites. Is it OK to feed bread to ducks? Bread is like junk food to ducks and geese because it doesn’t contain the nutrition they need from their typical diet in the wild. Foods like insects and aquatic plants contain more nutrients than carbohydrate-rich bread. How do ducks float? In addition to keeping them warm and helping them fly, ducks rely on their feathers to make them buoyant in water. Soft fuzzy down feathers keep a layer of warm air next to the bird’s skin. The larger vaned feathers create the contour of the duck and keep water out. ---+ Read the entire article on KQED Science: https://www.kqed.org/science/1968261/what-actually-makes-water-roll-off-a-ducks-back ---+ For more information: This 2016 study by scientists at the University of Debrecen in Hungary, shows that aquatic birds like ducks and geese not only have feathers with denser, more tightly knit microstructures than their terrestrial counterparts, but they also have more of them. https://besjournals.onlinelibrary.wiley.com/doi/full/10.1111/1365-2435.12820 ---+ More Great Deep Look episodes: What Makes Owls So Quiet and So Deadly? | Deep Look https://www.youtube.com/watch?v=a68fIQzaDBY&t=39s You've Heard of a Murder of Crows.

Cape Sundews Trap Bugs In A Sticky Situation | Deep Look

Teacher or professor: Deep Look
Subject: Biology
Content of the Lesson: Cape sundews are carnivorous plants that grow in bogs, where they don't have access to many nutrients. So they exude sweet, shimmering droplets from their tentacles to lure in unsuspecting insects. Once their prey is hopelessly stuck, they wrap it up and dissolve it for a tasty meal.

See the unseen at the very edge of our visible world. Explore big scientific mysteries by going incredibly small. --- If you have houseplants, most of the time there's not a lot of visible activity. But then there are carnivorous plants, like sundews. They aren’t content to just sit still. Typically found in habitats where other plants usually can’t thrive — like bogs with nutrient-poor soil — they often need to supplement their diet with nutrients like nitrogen and phosphorus. Carnivorous plants have developed a way to obtain these key nutrients from another source: insects. ---+ Read the entire article on KQED Science: https://www.kqed.org/science/1966521/cape-sundews-trap-bugs-in-a-sticky-situation ---+ Why must you use distilled water with carnivorous plants? “Many carnivorous plants have evolved carnivory in response to a substantial lack of nutrients in their native soils. As a result of living in nutrient-poor soils for so long, their root systems tend to be very sensitive to minerals. It’s like if you stayed inside for months, then went out on a sunny day. Your skin is going to be extra-sensitive and could burn easily. We give them rainwater or distilled water that has these minerals removed.” ---+ What happens to the exoskeletons of the insects after they finish digesting them? “Carnivorous plants can only digest soft tissues, and insect exoskeletons (made of out chitin and other proteins) are too tough and too nutrient-poor for them to digest. Exoskeletons are left behind after digestions and depending on the plant, can be washed away by rain, or simply just “hang out” on the leaf. Many carnivores can continue to catch insects even if there is an exoskeleton left behind as long as it doesn’t impede the mechanical trapping mechanism.” ---+ Do these plants have predators? “Yes! Traditional “pests” like grasshoppers, caterpillars, aphids, scale, mealybugs, etc. can chew holes in traps or weaken developing leaves. Many can avoid the traps themselves.” ---+ The above answers were provided by David Fefferman of the Carnivorous Plant Resource.

Content of the Lesson: Welcome to our new special series about the essentials of environmental science Like this video? SUBSCRIBE to Hot Mess! ►► http://bit.ly/hotmess_sub More info below… When I first took an environmental science class, I didn’t quite get why energy got its own section. Because in a lot of ways, energy feels so detached from the environment. In order to produce and move energy, we dig deep into the ground for fuel, we burn that fuel to create electricity, and we clear trees to make room for power lines. It all seemed in opposition to the environment. And in a lot of ways, it is, most energy production is entirely extractive. The extraction, and the resulting pollution from most energy sources has an immense impact on the environment, and that’s why we’ve got to talk about energy in the context of environmental science.

These Sneaky Ensatina Salamanders Are Heading For a Family Split | Deep Look

Teacher or professor: Deep Look
Subject: Biology
Content of the Lesson: Ensatinas are a sprawling group of colorful salamanders, each one with different strategies for avoiding predators, from bold warning colors to confusing camouflage. Their diverse family tree offers us a rare snapshot of millions of years of evolution – how one species becomes many. SUBSCRIBE to Deep Look! http://goo.gl/8NwXqt DEEP LOOK is a ultra-HD (4K) short video series created by KQED San Francisco and presented by PBS Digital Studios. See the unseen at the very edge of our visible world. Explore big scientific mysteries by going incredibly small. --- Even though they sport different colors and behaviors, and are spread out across the Western coastal states, from Canada to Baja California, they are still considered one species. That is because all types of ensatinas are able to mate and have offspring with each of their neighbors. But when researchers look more closely, the two types of ensatinas at the southern tips of their range — the Monterey ensatina and the large-blotched ensatina — only rarely mate and have offspring where their populations overlap. Some combination of genetic differences, habitat preference and behavior are keeping the lineages separate. This makes ensatina salamanders a rare example of a “ring species” — an animal that spread and adapted around a geographic barrier — in this case, California’s dry Central Valley — only to come back together millions of years later as near strangers. A ring species like the ensatina is unique in that it neatly illustrates the rich story of evolution — an idea that English biologist Charles Darwin and others have supported with countless studies since 1859, when Darwin published his landmark book “On the Origin of Species.” Evolutionary scientists are looking at ensatinas to build on Darwin’s original ideas about how species form; and as a way to help understand biodiversity all across the planet. ---+ Are ensatina salamanders poisonous? They can exude a slightly toxic milky substance from poison glands in their tails, but this substance is not dangerous to predators. ---+ What is the difference between a salamander and a newt? Newts are a type of salamander, belonging to a subfamily called Pleurodelinae of the family Salamandridae. Most newts have webbed feet and a paddle-like tail, which make it easier to live in the water during the aquatic stages of their lives. Salamanders typically have longer and more rounded tails with well-developed toes for digging in soil. ---+ More info Tom Devitt on ensatinas: https://evolution.berkeley.edu/evolibrary/article/0_0_0/devitt_01 More Barry Sinervo's work here: Lizards Have Been Playing Rock-Paper-Scissors for 15 Million Years” https://www.youtube.com/watch?v=rafdHxBwIbQ ---+ Read the entire article on KQED Science: https://www.kqed.org/science/1966227/these-sneaky-ensatina-salamanders-are-heading-for-a-family-split ---+ Shoutout! 🏆Congratulations🏆 to the following five fans on our Community Tab for being the first to name all 3 newt species the ensatina mimics!

The Importance of Soil | Essentials of Environmental Science

Content of the Lesson: Welcome to our new special series about the essentials of environmental science Like this video? SUBSCRIBE to Hot Mess! ►► http://bit.ly/hotmess_sub More info below… Let me make something super clear. If you take nothing else away, remember this: Soil is NOT dirt. Soil is productive, it’s useful. It’s fundamental to life as we know. It is an essential natural resource, a major component of most ecosystems, and has been celebrated in art and song for millenia. Dirt is just soil in the wrong place. Soil is the thin layer of inorganic and organic material wrapping the earth like a cozy blanket. It is where the abiotic lithosphere (that is, the upper mantle and crust of the Earth, the airless, unmoving underground stuff) meets all the living things in the biosphere.

See the unseen at the very edge of our visible world. Explore big scientific mysteries by going incredibly small. --- Bay Area biologists are studying a beautiful and exotic butterfly with the hope that their findings may one day improve technologies from eyeglasses to solar panels. Named for their transparent wings, glasswing butterflies have evolved a clever disappearing act to avoid their many predators in the rainforests of South and Central America. “Most things in the rainforest are either bright and flashy or they're trying their best to hide,” said Aaron Pomerantz, a doctoral candidate in the Nipam Patel Lab at UC Berkeley and the Marine Biological Laboratory. “There aren't a lot of things that are just trying to be invisible like the glasswings.” --- What are butterfly wings made of? A butterfly’s wings are mainly composed of chitin, the same tough flexible material that their exoskeleton is made of. Most butterflies’ wings and bodies are covered in row after row of tiny scales that protect the butterfly and keep water from sticking to their wing which would weigh them down. What do butterflies eat? Most butterflies use a long proboscis to drink nectar from flowers. As caterpillars, they mostly eat plants Why do butterflies have bright colors? Some butterflies try to stand out by using bright colors and clashing patterns that serve as a warning to predators. These butterflies typically eat plants rich in chemicals as caterpillars that make them poisonous or distasteful. This type of warning signal is called aposematism. ---+ Read the entire article on KQED Science: https://www.kqed.org/science/1964775/glasswing-butterflies-want-to-make-something-perfectly-clear ---+ For more information: The Patel Lab of Evolutionary Development at the Marine Research Institute in Woods Hole, MA http://www.patellab.net/ ---+ More Great Deep Look episodes: What Gives the Morpho Butterfly Its Magnificent Blue? | Deep Look https://www.youtube.com/watch?v=29Ts7CsJDpg Why Is The Very Hungry Caterpillar So Dang Hungry? | Deep Look https://www.youtube.com/watch?v=el_lPd2oFV4 The Double-Crossing Ants to Whom Friendship Means Nothing | Deep Look https://www.youtube.com/watch?v=fguo3HvWjb0 ---+ Shoutout! 🏆Congratulations🏆 to the following fans on our Deep Look Community Tab for being the first five to correctly identify the microscopic waxy structures that stop the glare on glasswing butterfly's wings: nanopillars!
