What’s the difference between a tarantula and a spider?

Tarantulas are spiders that are members of the Theraphosidae family and there are around 900 species of tarantula worldwide. They make up only two percent of the 50 000 spider species found on the planet and are nowhere near as deadly as many people think.

Although feared around the world, tarantulas have venom weaker than a bee sting and have some very clever adaptations indeed. They regularly shed their skins and can even regrow lost limbs. Females can lay more than 1000 eggs at a time, and after mating males have to make a quick getaway if they don’t want to get eaten.

Tarantulas can go without food for a month and don’t use webs to catch their prey. Tarantulas are sit-and-wait predators that ambush passing animals, but they can use webs as trip wires to give than warning that something’s approaching.
