Cynodontidae, also known as dogtooth characins or vampire tetras, are a family of predatory, characiform freshwater fishes from South America. This group is not very diverse, and includes only five genera and 14 species. Most of what is known about this family is from the members of the subfamily Cynodontinae, which includes the largest species of this family, up to 117 cm (3.84 ft).[1] The members of subfamily Roestinae only reach up to 20 cm (7.9 in).[2] and are less known.
Cynodontidae are elongated in shape with a silvery or grey colour and an upturned mouth. Some species have a hunchbacked appearance. The family names (both scientific and common) derive from the long and well-developed canines which are used to spear their prey, mainly other fish. Their pectoral fins are also expanded. The maximum length reached is 117 cm (46 in).[1]
