Gray tilefish, Caulolatilus microps, were collected from 1972 to 1977 between depths of 70 to 236 m off North Carolina and South Carolina. Gray tilefish are demersal, opportunistic predators that consume fishes and macroinvertebrates closely associated with the substrate. The
principal components of their diets, in decreasing order of importance, are: crabs, shrimp, fish, echinoderms (holothurians, echinoids, stelleroids), polychaetes, ascideans, molluses (gastropods and bivalves), stomatopods and sipunculids. As tilefish grow, they consume larger prey. Their generalized
feeding is similar to other branchiostegids. This strategy is advantageous for predation on the faunal assemblages of the shelf-edge habitat where the species diversity is generally high, but the number of individuals/species is generally low.
The Bulletin of Marine Science is dedicated to the dissemination of high quality research from the world's oceans. All aspects of marine science are treated by the Bulletin of Marine Science, including papers in marine biology, biological oceanography, fisheries, marine affairs, applied marine physics, marine geology and geophysics, marine and atmospheric chemistry, and meteorology and physical oceanography.
