Goliath Bird-eating Spider

Goliath Bird-eating Spider


Northern South America


Rain forests, living in burrows in ground.


This goliath has 8 legs covered in a dark brown hair and at each leg joint the hairs lighten to almost white. The cephalothorax (head) and abdomen are dark brown covered in reddish hairs, which gives it a golden-blond appearance. The two fangs are large enough to break the skin of a human, although it is considered fairly harmless to humans. It has 8 eyes but does not see well.

Goliath Bird-eating Spider

This is a nocturnal spider that lives in deep burrows. They do not dig their own, but inhabit abandoned burrows dug by rodents and other small animals. These spiders do not form partnerships and are around other adult spiders only long enough to mate. It is a aggressive spider and when threatened, it has the ability to hiss loudly by rubbing the bristles on its legs together (called stridulation). They can also propel a cloud of hairs off their body at their attacker. These hairs are barbed and can cause severe discomfort and irritation.


Male entices the female out of her burrow and they mate at the entrance. Several days later she lays her eggs in a silken sack. She then stores the egg sack in her burrow and protects it with a tough layer of silk. After an incubation period of 2 - 3 months the eggs hatch, revealing more than 100 spiderlings. These babies only stay in the mother’s burrow for their first few weeks, and then they move out to find a burrow of their own.

Interesting Facts:

The Goliath bird-eater was named during Victorian times when explorers in South America saw one eating a hummingbird.


Tarantula populations are under pressure from habitat destruction, whether in tropical rainforests or in deserts. Many suffer the effects of pesticides used to kill insect “pests” that they depend on for food.
