Arachnids

Bowie was right; there really is a "spider" from Mars.

Like the white-armored and -helmeted Stormtroopers from "Star Wars," these spiders are tough to tell apart.

In the Amazon lowlands, spiders as big as dinner plates dine on opossums.

A new species of tarantula has something in common with the mythical unicorn — a prominent "horn."

Sometimes spiders scare people so much that the cops have to deal with it.

There's a whole range of reasons you don't want to be bitten by a black widow spider, but you probably wouldn't think that losing the ability to pee is one of them.

Don't worry; it's for mating.

Ever wonder what it looks like when 1,400 tarantulas are born all at once? Wonder no more.
