The hippo was a popular member of the zoo's Africa Live! exhibit, one which "brought millions of guests closer to hippos than they could ever have imagined," according to the zoo's Facebook page.
Aside from local lore, Tumbo was also made famous by National Geographic photographer Joel Sartore, who captured vivid images of the hefty ungulate for his Photo Ark project. Sartore hopes to document as many animal species as possible— with the help of zoos, aquariums, and wildlife sanctuaries— before they go extinct. His project, along with fantastic portraits of Tumbo, can be viewed here.
