Where Do Tarantulas Live?

Where Do Tarantulas Live?

When most people think of a tarantula, they think of the Mexican red-kneed tarantula, known scientifically as Brachypelma smithi. There are actually many varieties of spiders classified as tarantulas, though. Depending upon how they’re categorized, spider experts believe there are approximately 650-900 species of tarantulas.

True tarantulas belong to the scientific family named Theraphosidae. They can be found in warm areas on every continent except Antarctica, with the greatest concentration being found in South America. They often go by other names, such as bird spiders, monkey spiders, baboon spiders, or rain spiders.

As spiders go, they do tend to be big and hairy, but they’re usually not as large as people imagine them to be. Most are quite small (less than a couple centimeters long). The exception is the world’s largest spider (by mass): the Goliath birdeater (Theraphosa blondi), which can be as large as a dinner plate!

The tarantula traces its history to the common wolf spider found in the city of Taranto in southern Italy. Residents of Taranto thought the wolf spider was killing people, but it’s not dangerous. Historians believe it was actually the black widow spider that was responsible for deaths in the area. Nevertheless, residents came up with a unique antidote to its venom: a vigorous dance they called the Tarantella. It is from this dance and town that the name tarantula was born.

Tarantulas also don’t hunt down humans like prey like you may have seen in a scary movie. They’re not naturally aggressive and tend to avoid humans. They do have fangs and venom, which they use to subdue prey, such as insects, other spiders, and small frogs, mice, birds, snakes, and lizards. Their venom isn’t deadly to humans, though. For a human, a tarantula bite is similar to a bee sting.

From time to time, you may see what looks like a tarantula but is actually an empty shell. As young tarantulas experience growth spurts, they shed their hard exoskeleton in a process called molting. Most tarantulas molt several times during the first few years of their lives as they grow larger.
