"Pyxicephalus adspersus" - as this X-ray clearly shows, they're just big boned, not fat. They're also called pixie frogs for their beauty and grace in the water and gentle nature, which will not allow them to harm another living creature (unless it gets close to them, in which case they'll most likely swallow it whole; or if it's a predator, bite them. They do have teeth) Males will also guard their tadpoles (unless they get hungry, then they just eat them)
