Dorsal spines (total): 7-7; Dorsal soft rays (total): 9-9; Anal spines: 1-1; Anal soft rays: 9-10.

| Biology: |
This species is found in clear, high gradient streams with rocky bottom. It lives on the bottom, on top of rocks, and often seen swimming in open water in the current between rocks or in large pools. Like its congeners, it is presumed to spawn in freshwater, the free embryos drift downstream to the sea where these undergo a planktonic phase, and before returning to the rivers to grow and reproduce (Ref. 85524). |
