Tarantulas have a worse reputation than they deserve. They’re big, hairy, eight-legged, and they show up in plenty of scary movies. But for almost all of the roughly 1,000 tarantula species, a bite to a healthy human is no worse than a bee sting - sore for a few hours, sometimes a bit swollen, and then gone. No tarantula bite has ever been recorded as killing a person.
A tarantula would rather not bite you at all. Its real defense is the carpet of fine hairs on its belly. When something pushes it too hard, the tarantula uses its back legs to kick a cloud of these hairs at the threat. The hairs are barbed and itchy, like tiny darts, and a face full of them is much more useful to the spider than wasting precious venom.
That doesn’t mean you should grab one. Some species can still give a nasty pinch, and the belly hairs really do sting eyes and noses. But the next time someone screams about a tarantula in a movie, you can quietly remember: the scariest-looking spider in the room usually has a bite weaker than the bee that landed on your soda this morning.
