Tarantulas are some of the most misunderstood — and underrated — creatures in the animal kingdom. Whether you’re a new keeper or lifelong arachnophile, here are 11 facts that might just blow your mind.
From the neon-blue Caribena versicolor to the chunky Theraphosa blondi, tarantulas are one of the most diverse groups of spiders.
Fossil evidence shows tarantula ancestors dating back to the Cretaceous period. That’s older than many dinosaurs!
Unlike web-building spiders, tarantulas ambush or stalk their food. But they do use silk for lining burrows, egg sacs, and moult mats.
Female tarantulas of some species can live for decades — making them a serious long-term commitment.
The Goliath birdeater can make a hissing sound called stridulation by rubbing body parts together. Intimidating, but harmless.
No ears — but extremely sensitive hairs detect tiny changes in air pressure and movement around them.
Old World species (like African or Asian tarantulas) rely more on speed and venom, while New World species often flick hairs as a defense.
During a moult, a lost or damaged leg can regrow — though it may take multiple moults to look normal again.
Some tarantulas will lie motionless or curl up when threatened. It’s not always a death curl — sometimes it’s a bluff!
From metallic green to deep purple and orange, tarantulas can be surprisingly vibrant thanks to microscopic structures in their hairs.
Tarantula venom and silk are being studied for medical applications, including cancer research and biodegradable materials.
