- Have You Met a Hagfish? It’s About SlimeE1
Have You Met a Hagfish? It’s About SlimeWhat keeps the boneless, jawless hagfish thriving after more than 300 million years? SLIME. The goop it exudes – a mix of mucus and special protein cells– expands to 10,000 times its original volume in less than half a second, potentially clogging the gills of competitors. - How Does the Mussel Grow its Beard?
E3How Does the Mussel Grow its Beard?Mussels create byssal threads, known as the mussel's "beard," to attach themselves both to rocks and to each other. They use their sensitive foot to mold the threads from scratch and apply a waterproof adhesive that makes superglue jealous. - What Makes This Frog's Tongue So Fast AND Sticky?E4
What Makes This Frog's Tongue So Fast AND Sticky?How are frogs and toads so amazing at catching bugs? They smack ’em with a supersoft tongue covered in special spit, which flows into every nook and cranny of their target. Then, in less than a second, that spit transforms into a tacky glue, yanking the meal back into the toad’s maw. - Gecko Grip: It’s Atomic (Really)
E7Gecko Grip: It’s Atomic (Really)Gecko feet aren't covered in suction cups or Velcro. They don’t squirt glue, or leave any footprints. Their secret is a herculean amount of grip -- at the atomic scale. A gecko’s toes are covered in tiny hairs that branch out into millions of microscopic, spatula-shaped pads. Those pads, called spatulae, get so close to the surfaces on which a gecko moves, the electrons of the spatulae and those on the surface start to sync up. That dance is called Van der Waals force, and it’s what gives geckos their sticking power. - Springtails Do Their Own Stunts
E8Springtails Do Their Own StuntsStep right up to see tiny springtails spin through the air with the greatest of ease! In ponds and streams, they skyrocket out of the reach of hungry insects like water striders by slapping a tail-like appendage against the water. And you won’t believe how they stick the landing. - This Snail Goes Fishing With a Net Made of Slime
E9This Snail Goes Fishing With a Net Made of SlimeMost of the sea snails in this tide pool cruise around searching for food. But not the scaled wormsnail. It cements its shell to a rock and snags its meals using the one thing a snail has plenty of: mucus! - This Fly Torpedoes a Bindweed Bee’s Nest
E10This Fly Torpedoes a Bindweed Bee’s NestA “bee fly” looks a bit like a bee, but it’s a freeloader that takes advantage of a bindweed turret bee’s hard work. The bees dig underground nests and fill them with pollen they collect in the form of stylish “pollen pants.” As the bees are toiling on their nests, the flies drop their own eggs into them. But the bees employ a tricky defense against the flies. - This Daring Fly Swims in a Shimmering Bubble ShieldE11
This Daring Fly Swims in a Shimmering Bubble ShieldCovered in a shiny bubble, the alkali fly scuba dives into the harsh waters of California's Mono Lake. Thanks to an abundance of hair and water-repellent wax, this remarkable insect remains dry while embarking on a quest for tasty algae and a place to lay its eggs. - Cockroach vs. Hydraulic Press: Who Wins?E12
Cockroach vs. Hydraulic Press: Who Wins?Do cockroaches -- those daring, disgusting disease vectors -- have anything at all to offer us? Scientists think so. They compressed American roaches with a hydraulic press, subjecting them to the force of 900 times their body weight. Don't worry (or do): They survived! How exactly do they do it? - Watch Ladybugs Go From Goth to GlamE13
Watch Ladybugs Go From Goth to GlamLadybugs may be the cutest insects around, but they don't start off that way.| Also called lady beetles or ladybirds, they pop out of their eggs as prickly mini-monsters with an insatiable hunger for aphids. Once they've bulked up, they transform, shedding their terrifying looks, but keeping their killer vibes. - Varroa Mites Are a Honeybee's 8-Legged NightmareE14
Varroa Mites Are a Honeybee's 8-Legged NightmareEvery year, up to half the honeybee colonies in the U.S. die. Varroa mites, the bees’ ghastly parasites, are one of the main culprits. After hitching a ride into a hive, a mite mom hides in a honeycomb cell, where she and her offspring feed on a growing bee. But beekeepers and scientists are helping honeybees fight back. - This Weevil Has Puppet Vibes But Drills Like a Power ToolE15
This Weevil Has Puppet Vibes But Drills Like a Power ToolThis fuzzy acorn weevil can’t crack open acorns like a woodpecker or chomp through them like a squirrel. Instead, she uses her incredibly long snout, called a rostrum, to power-drill through an acorn’s tough and resilient shell. And it's not just lunch on her mind – she's also making a nursery for her babies. - Mom, Where Do Baby Jellyfish Come From?
E17Mom, Where Do Baby Jellyfish Come From?When grown-up jellyfish love each other very much, they make huge numbers of teeny-tiny potato-shaped larvae. Those larvae grow into little polyps that cling to rocks and catch prey with their stinging tentacles. But their best trick is when they clone themselves by morphing into a stack of squirming jellyfish pancakes.
