2 / 2

  • The gestation period is 6 weeks. The female constructs an egg sac and lays a large number of eggs (from 80 to over 1000). She will carry the egg sac around with her and aggressively guard it against any intruders until the spiderlings emerge.


  • In the Wild: insects and other arthropods, sometimes small animals (cannot swallow solid food)

  • At the Zoo: crickets

Conservation Status

  • IUCN status: not listed; CITES Appendix: not listed

  • Because of the wide-spread collection of this species from the wild for the pet trade, increasing regulation in the future is probably inevitable in order to protect it from becoming threatened and/or endangered. There are a number of other tarantula species in the world that are currently protected, and several more may be in the future. There are a few laws in effect now, but this is an area mostly unregulated at the present time.

  • Predators: various nocturnal animals (large mammals, reptiles, other tarantulas), hunting wasps, parasitized by nematodes or roundworms

Did You Know?/Fun Facts

  • The Chilean rose-haired tarantula is the hardiest of tarantulas and is easy to find in captivity. Although it has a reputation for being docile (calm), it varies widely from individual to individual. They may become nippy.

  • Hairs on the abdomen have been modified to serve as defense weapons. They possess sharp tips with microscopic barbs. When threatened, the tarantula will use its back legs to kick off a cloud of hairs at its attacker.

  • In most tarantula species the female will live for twenty years or more, but the male may survive only the few years required to reach maturity. Once the male has fulfilled the biological function of mating, it usually will die of natural causes or the female may eat him. The male’s lifespan is further shortened by the stress of captivity.

  • All tarantulas have a certain amount of venom. Although most people are not affected by this species, some people may be allergic to its venom, or just more sensitive, making it a dangerous situation. This is one of the reasons why people should not handle this tarantula.
