What Types of Tarantulas Exist, and How Dangerous They Are?

There are more than 850 types of tarantula discovered by researchers. While we often see usual black and brown insects that are kept in zoos and personal collections, there are many other interesting species around the world. This article describes most widespread and most interesting species.

General information about species

The biggest spider in the world, tarantula is a bug that is hard to mistake for any other arachnid. It has hairy body and stout legs, and its fangs remind of vampire’s teeth.


This is a nocturnal creature that lives mostly in tropical and sub-tropical areas, and can also be met in some warm regions around the world (Central and South America, the USA, Africa, Asia, Australia and partially Europe). Most bugs live underground in burrows, and make silk to protect their shelter and to facilitate movement around. Some of them may live on trees, but still hunt on the ground.

What do tarantulas eat? Although they are called bird eaters, most species feed with other spiders, insects and arthropods, and bigger species may hunt snakes, frogs, mice, lizards and tiny birds. After catching a prey and poisoning it, a bug injects digestive juices into it, and sucks it after some time. After such a rich lunch, it may live without nutrition for about a month.


How long do tarantulas live? Females live up to 30 years, while male’s lifespan is far shorter – 7 years. It is partially connected with the fact that females may eat their partners after mating.

Few facts
