Distichodontidae
Template:Short description Template:Automatic taxobox
The Distichodontidae are a family of African freshwater fishes of the order Characiformes.[1]
Two evolutionary grades are found in this family; micropredators (predators of very small organisms like aquatic insect larvae) and herbivores have a nonprotractile upper jaw and a deep to shallow body, while carnivores have a movable upper jaw and an elongated body.[1] Although the herbivores primarily feed on plant material, these species often have omnivorous tendencies. The carnivores include specialized fish-eaters (genus Mesoborus), fin-eaters (Belonophago, Eugnathichthys and Phago) and species that will feed on both whole fish and fins (Ichthyborus). The fin-eaters attack other fish, even ones that are much larger, where they bite off pieces of fins with their sharp teeth.[2][3][4]
The fish in Distichodontidae vary greatly in size among species, with the smallest micropredators being less than Script error: No such module "convert". in length, and the largest herbivores can reach up to Script error: No such module "convert"..[5]
