The grunt sculpin or grunt-fish (Rhamphocottus richardsonii) is a small fish mainly found in the eastern Pacific Ocean. The grunt sculpin generally remains close to shore and is often found in empty giant barnacle shells. The common name comes from reports that the fish vibrate or "grunt" when held.
