Remarks | Ratio of digestive tube length/standard length: 0.7. Perform the sit-and-wait predation in which the fishes remain among the rocks and use their paired fins to rest on the bottom. They visually inspect the nearby substrate areas and, whenever a prey is detected, they swim towards it very fast, thrust against the substrate and grab it with their mouths (Ref. 27701). |
