  • Found from South Western U.S.A. down to Chile, from China down to Australia.


  • Tibal spurs or hooks appear on the first pair of legs (not the pedipalps which are on either side of the mouth).
  • These will eventually be used by the male to help it hold the female up while it inseminates her using it’s modified pedipalps which get rounded and look sort of like the tarantula is wearing boxing gloves.
  • Before a male tarantula matures there’s another way to tell the difference between male and female tarantulas, and that’s by waiting until a tarantula moults, and then sexing that left over exoskeleton.
  • The idea behind this is simple. The female tarantula’s spermathecae (or sex organs), a small pouch which the semen is stored in, are quite easily seen.
  • Even spiderling female tarantulas have this spermathecae, which could be visible with a nice microscope, and as the tarantula grows it eventually becomes easy to see even with the bare eye, or a small hand held magnifying glass or lens.
  • The male tarantula, on the other hand, usually has just a crease, or fold in the skin.

  • In The Wild Diet: Carnivorous (meat-eating); They will eat just about any animals it can overpower, e.g. insects, mice, frogs, snakes, other spiders and even bats. Some will gorge themselves on as much as they can and others will stick to an apparent diet.
  • Captive Diet: Insects (e.g. crickets, roaches, worms), occasionally pinkie mice or rats, Sometimes they fast for long periods for unknown reasons and they almost always avoid eating when they’re about to molt
