Life in the flow lane: differences in pectoral fin morphology suggest transitions in station-holding demand across species of marine sculpin.

Aquatic organisms exposed to high flow regimes typically exhibit adaptations to decrease overall drag and increase friction with the substrate. However, these adaptations have not yet been examined on a structural level. Sculpins (Scorpaeniformes: Cottoidea) have regionalized pectoral fins that are modified for increasing friction with the substrate, and… CONTINUE READING
