Costa Rican Zebra Tarantula Aphonopelma seemani
This strikingly beautiful arachnid lives in burrows in the Central American rainforest (or perhaps humid grasslands--there was some confusion about this in online sources). It's a quick hunter, known among tarantula hobbyists as "skittish" and possessing "a liberal dose of Houdini genes." Males have a bluish cast to the hairs on their legs, and are reputed to be very aggressive, sometimes biting their owners. Scientific information on this species was hard to come by although I did find a journal abstract which promised to explain that this animal's venom "induces necrosis of skeletal muscle in mice."
This individual (a female, I believe) lives in the Bird's World exhibit.
