Chiapas Catfish

The Chiapas catfish, Lacantunia enigmatica, is an unusual species of catfish (Order Siluriformes) newly described in 2005 from the Lacantún River in the Mexican state of Chiapas. While discovery of an undescribed species of catfish is not uncommon, discovery of a new family-level taxon of any vertebrate group is a rare event. The Chiapas catfish mainly feeds on crabs, prawns, small fish, and large, tough plant seeds. This catfish is commonly fished in its natural habitat, where it is known as madre de juil, which means "mother of Rhamdia" (a common fish in the area).
