Feeding kinematics of a surgeonfish reveal novel functions and relationships to reef substrata
Abstract Biting to obtain attached benthic prey characterizes a large number of fish species on coral reefs, and is a feeding mode that contributes to important ecosystem functions.We use high-speed video to reveal the mechanisms used by a surgeonfish, Acanthurus leucosternon, to detach algae.After gripping algae in its jaws, the species pulls it b
