The triplewart seadevil, Cryptopsaras couesii, is a sea devil of the family Ceratiidae, found in all oceans, from the surface to 2,000 m (6,600 ft). Its length is about 30 cm (12 in) for females and 1.05 cm (0.41 in) for males.[1] This species is the only known member of its genus.

Sexual dimorphism[edit]

The species displays extreme sexual dimorphism. Females are more typical in appearance to other anglerfishes, whereas the males are tiny rudimentary creatures with stunted digestive systems. A male must find a female and attach to her near the vent; he then lives on her parasitically, becoming little more than a sperm-producing appendage.
