A Tiny, Toothy Catfish with Bulldog Snout Defies Classification

Kryptoglanis shajii is a strange fish — and the closer scientists look, the stranger it gets. This small subterranean catfish sees the light of day and human observers only rarely, when it turns up in springs, wells and flooded rice paddies in the Western Ghats mountain region of Kerala, India. Scientists at the Academy of Natural Sciences of Drexel University have recently provided a detailed description of this fish's bizarre bone structures.
