The Fishes: Sternopygidae
There are currently 23 sternopygid species which are grouped on the basis of dentition, skeletal structure and sensory pores. Genera include Distocyclus, Eigenmannia, Rhabdolichops, and Sternopygus. These are essentially nocturnal animals that remain undercover by day. At night they will enter open water in search of prey. [eng] |
