Fun Fact(s):
Called “Baboon Tarantulas/Spiders” due to last 2 leg segments resembling baboon fingers.
Often kept by experienced tarantula keepers-these spiders highly defensive, displaying readily if bothered & biting. While not lethal, venomous bite quite painful.
Only tarantula that can swim, sometimes diving to catch fish/frogs/other aquatic prey. Has been submerged underwater for up to 2 hours.
Molting done by splitting of old exoskeleton & wriggling out of it. Fangs part of exoskeleton, also being shed. They don’t eat during or the week right after molting. Lost limbs sometimes regenerated as well.
Since they can’t eat prey whole due to lack of teeth, food predigested w/ venom from fangs, containing digestive enzyme helping break down/liquefy prey.
