Tarantula Spider Classification

Tarantulas are spiders that belong to the Theraphosidae family, and they are some of the largest spiders in the world. There are more than 900 different species of tarantulas, and they can be found on every continent except for Antarctica. Tarantulas are carnivorous animals, and they typically hunt at night.


Tarantulas are generally shy and reclusive creatures, but they can be aggressive if they feel threatened. When they feel threatened, tarantulas will sometimes rear up on their hind legs and show their large fangs. They may also urinate on their attacker as a form of defense. Tarantulas are not considered to be dangerous to humans, but their bites can be painful and cause swelling.


If you're thinking about getting a tarantula as a pet, there are a few things you should know first. Tarantulas can live for 20 years or more in captivity, so you need to be prepared for a long-term commitment. Tarantulas also need special care and housing, and they are not ideal pets for everyone.

Tarantula Spider Behavior

Tarantula spiders are large, hairy spiders that can be found in warm climates all over the world. They are popular pets, but before you buy one, there are a few things you should know about their behavior.


Tarantulas are nocturnal creatures, so they are most active at night. During the day, they hide in their burrows or among the leaves and branches of trees.


When they feel threatened, tarantulas can release urticating hairs from their abdomens. These hairs irritate the skin and eyes of predators and can even cause temporary blindness.


Tarantulas are also capable of biting, but their venom is usually not harmful to humans. However, some people may experience an allergic reaction to the venom, so it's best to be cautious if you're considering a tarantula as a pet.

Tarantula Spider Size

Tarantula spiders come in a wide range of sizes, with some species reaching up to 10 inches in length. If you're thinking about getting a tarantula spider as a pet, be sure to research the size of the specific species you're interested in. Some tarantula spiders can grow quite large and may not be suitable for everyone.

Tarantula Spider Lifespan

Tarantulas are one of the longest-lived spiders, with some species living for up to 30 years. However, their life expectancy in captivity is much shorter, typically only 10 to 20 years. While they may not live as long as some other pets, they can still provide years of enjoyment.

Do Spiderlings Grow into Adult Tarantulas?

No, spiderlings do not grow into adult tarantulas. Tarantulas reach full size after about two to three years. Once a tarantula reaches adulthood, it will only grow larger in body size, not in leg span.

Why are tarantulas the most popular spiders?

There are many reasons why tarantulas are the most popular spiders. They are relatively easy to care for, they are interesting to look at, and they can make great pets. Tarantulas are also relatively docile spiders, which makes them less likely to bite humans.
