Ctenocheirodon is a monospecific genus of freshwater ray-finned fish belonging to the family Characidae.[2] The only species in this genus is Ctenocheirodon pristis, a characin,[3] which is endemic to the drainage basin of the upper Tocantins River in Brazil.[1] This species has a fusiform body with a maximum standard length of 3.4 cm (1.3 in) in females and 3.3 cm (1.3 in) in males. It occurs in clear water over sand and gravel substrates with no vegetation.[4] The genus name prefixes Cheirodon with cteno, which means "comb", and the specific name pritis, means "saw", both names being a reference to the "ventral procurrent caudal-fin arrangement of males".[5]
