Brush-tailed Porcupine

I just saw one of these animals at Omaha's Henry Doorly Zoo last week and off the top of my head I cannot think of any other zoo in the USA that holds this species in captivity. (There must be a couple of places but they don't come to mind.) I would imagine that this species is much more common in Asian zoos.

@snowleopard - the species at Omaha is the African Brush-tailed Porcupine.

Prospect Park has several of the African species.
