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.

Habitat

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.

Nutrition

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.

Lifespan

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

This is one of the most interesting insects on the Earth. You can be surprised to learn that:

  1. Although these arachnids have few enemies in nature, tarantula hawk wasp is one of the most dangerous creatures for them. When it stings a spider, it lays eggs inside the wound. Newly hatched larvae eat the host from the inside.
  2. This species is widely used as an exotic pet, and is also considered to be a gourmet item in many Asian countries.
  3. Tarantula spider may throw its hairs off when being attacked. It is considered that hairs irritate eyes considerably.

But usually they attack only in self-defense, and often perform a “dry bite” (without envenomation).

It fangs are 2 cm long, and can easily pierce human skin through clothes and leather shoes. Its venom is quite mild, and may trigger minor irritation and swelling.
