Ecology Summary - Sewellia lineolata

Language:

Main Ref.	Rainboth, W.J., 1996
Remarks	Rheophilous, inhabits rapids and riffles, found in a variety of streams and small rivers. It occurs in small streams with large and deep pools covered by submerged plants, provided that small riffles are present between these pools. Also found in high gradient streams consisting almost exclusively of waterfalls. Also occurs in larger rivers, at the upper extremity of riffles where current velocity do not exceed 0.2 m/sec, as well as habitats with high water velocities exceeding 1 m/sec. Stomach contents include benthic invertebrates and algae. Observed to be active during daytime searching in the periphyton on both horizontal and vertical surfaces of stones probably searching for aquatic invertebrates (Ref. 40433).
