Goliath Birdeater chilling out on a freakin dinner plate.
Hailing from the tarantula family and native to rainforests in South America, these fuzzy giants grow to about 1 foot or 30 centimeters across. It's fangs are an inch long. So in other words, think of a dinner plate or a medium pizza, and its legs would span that size.
Just in case that's not terrifyingly creepy enough, it can generate a scary hiss when threatened that's audible from upto fifteen feet away.
Oh also it has the ability to shoot tiny barbed hairs at you or any other threat, which cause irritation to humans and can be a problem if they get on your face or nose or mouth.
All that scariness aside, it's generally not harmful to humans and will only bite a human when threatened, often biting without using poison, called a dry bite. Its poison causes pain and irritation for a few hours and is similar to a wasp bite.
It's called the Goliath Birdeater because when it was first discovered by Victorian era exploreres, it was spotted eating a goddamn hummingbird. No, seriously. Although they generally prefer to snack on frogs, small snakes, beetles, insects, lizards, bats and rats.
Unlike most spiders it doesn't weave a web, but lives in burrows and stalks and kills its prey like a cat.
I, for one, welcome our new giant eight legged overlords of doom.
