Despite the name 'centipede' (Latin: 100 feet), no centipede actually has 100 legs — counts are always odd-paired numbers like 21, 23, or 47.

A centipede's front pair of legs aren't legs — they're modified into venom-injecting fangs called forcipules.

The giant huntsman has the largest leg span of any spider — up to 30 cm across, the size of a dinner plate.

Huntsman spiders don't build webs — they hunt on foot, with a distinctive fast sideways gait that gave the family its name.

The species was only described in 2001 — found in karst caves in central Laos by Senckenberg Museum arachnologist Peter Jäger.

Despite being the largest spider in the world, the huntsman's venom is medically mild — bites are rare and resolve without intervention.

Female huntsmans carry flat egg sacs under their bodies and aggressively defend hatched spiderlings — a level of maternal care unusual among spiders.

Australian huntsman cousins (Heteropoda venatoria) regularly cause traffic incidents — they shelter behind sun visors and drop into laps at the worst possible moment.

Glasswing butterfly wings are transparent — you can read text through them.

Nano-pillars on glasswing butterfly wings reduce light reflection to under 2% — better than most engineered anti-glare coatings.

Glasswing caterpillars eat toxic Cestrum plants and store the alkaloids — making the adults distasteful to predators.

Glasswing wing structure has inspired patented anti-glare coatings for camera lenses, phone screens, and solar panels.

The transparent wings function as living camouflage — predators struggle to track the butterfly against any background.

Glow-worms are not worms — they're the larvae of fungus gnats.

Each larva hangs dozens of silk fishing lines studded with sticky mucus beads — a personal trap for flying insects.

The blue-green light comes from a unique luciferase — biochemically distinct from fireflies.

Waitomo Cave's ceiling can hold tens of thousands of glow-worms — looking up resembles staring at an inverted Milky Way.

Adult glow-worms have no mouth — like atlas moths, they exist as adults only to mate, then die in days.

Goliath beetle larvae can weigh 80–100 grams — heavier than the adult that emerges from them.

Lab tests have measured Goliath beetles lifting up to 850× their own body weight — pound for pound, one of the strongest animals ever measured.

Goliath beetle larvae are carnivorous — they eat decomposing meat and other invertebrates, unusual for a scarab beetle larva.

Despite weighing as much as a hummingbird, Goliathus can fly — though it sounds like a small drone in flight.

The Goliath beetle's wing covers are so thick and rigid that researchers have studied them as a model for impact-resistant materials.

Captive-bred Goliath beetles are popular pets in Japan, where they are kept in climate-controlled enclosures and traded among collectors.

By body mass and length, the goliath birdeater is the largest spider on Earth — up to 175 grams and 11 cm body length.

The 'birdeater' name comes from a single 1705 illustration by Maria Sibylla Merian showing one eating a hummingbird in Suriname — three centuries of branding from one watercolor.

Goliath birdeaters defend themselves by kicking off clouds of barbed urticating hairs from the abdomen — they cause intense itching and respiratory irritation in mammals.

When alarmed, goliath birdeaters rear up and produce an audible hiss by rubbing the bristles on their legs together — heard from up to 15 feet away.

Roasted goliath birdeater is a traditional Venezuelan and Guyanese delicacy — flavor is reportedly close to shrimp.

Despite the fearsome size, goliath birdeater venom is medically mild — bites are painful but no worse than a wasp sting.
