Catfish (order Siluriformes) are a diverse group of fish. Named for their prominent "barbels", which give the image of cat-like whiskers, they are found in freshwater environments of all kinds, with species on every continent except Antarctica. Some species from the families Ariidae and Plotosidae are also found in marine environments. They feature some of the smallest known vertebrates, including the candiru, the only vertebrate parasite to attack humans, as well as Pangasius gigas, the largest reported freshwater fish. There are armour plated types and also naked types, but they do not have scales. Not all catfish families have barbels; what defines a fish as being in the Siluriformes order are certain features of the skull and swimbladder.
Catfish belong to a superorder called the Ostariophysi, which also includes the Cypriniformes, Characiformes, and Gymnotiformes (although some place Gymnotiformes as a sub-order of Siluriformes). As of 2005 there are 37 catfish families, and around 2000 species have been described, although this number is in constant flux due to taxonomic work on the order.
In June, 2005, researchers named the 37th family of catfish, Lacantuniidae, only the third new family of fish distinguished in the last 70 years (others being the coelacanth in 1938 and the megamouth shark in 1983). The new species in Lacantuniidae, Lacantunia enigmatica, was found in the Lacantun river in Chiapas, Mexico.
