Explanation

A tarantula is a hairy, poisonous, black spider. Although they are furry and some people keep them as pets, you probably don't want to cuddle up to one. Tarantulas are found primarily in subtropical South America. Their leg spans can range from three to twelve inches, which means that a very big tarantula is about as wide as a cowboy hat! While their bites are poisonous, you won't die from tarantula venom, unless the bite gets infected.
