The spiders are generally characterized as nocturnal. They live in burrows in the ground that they create or that were created by other creatures. The males tend to spend more time outside of their homes than the females, but the males do not generally travel long distances.

A common characteristic of tarantulas is that they are hairy spiders. The goliath bird-eating spider uses its hairiness for one of its defense mechanisms. This spider has the ability to shoot hairs from its body at whatever it considers to be an enemy. This ability may be considered fairly impressive because these spiders have poor eyesight and tend to rely more on the detection of motion than they do on vision.

This spider's hairiness gives it another ability that most other spiders do not have. It can break the silence by making a hissing noise. The sound is generated if the creature rubs the bristles on its legs together.
