This species is commonly seen on seaward reefs and in the lagoon, including interisland reefs, pinnacles and shipwrecks. While it usually swims freely above the bottom, it feeds by digging in the sand for burrowing mollusks and perhaps echinoderms. We have seen them crunching up bivalve and gastropod mollusks, swimming away with small chunks of shell dribbling from their chewing jaws.
They sometimes come into shallow water. These four were in less than a half meter of water right in Kwajalein harbor.
