| Coryphaenoides rudis Günther, 1878 |
The rudis rattail, Coryphaenoides rudis, is a fish of the family Macrouridae, found in all the world's tropical and subtropical oceans, at depths of between 600 and 2,300 m. Its length is between 30 and 40 cm, although FishBase gives lengths of up to 1.1 m.
The rudis rattail has the usual greatly elongated pointed tail of the rattails, as well as large eyes, but a slightly smaller head with no pronounced bony ridges. The scales have longer spines than other members of this genus.
Color is uniformly dark brown with black edges to the eye and operculum, and anal fin.
The rudis rattail feeds on a variety of cephalopods as adults.
