The shelf is wide (up to km) off the Florida peninsula and off northern Texas and Louisiana, and narrower off the Florida Panhandle near DeSoto Canyon, the Mississippi River Delta, and southern Texas. The continental slope is a steep escarp­.

Three taxa are most abundant over the slope, and six others are found most commonly over the continental shelf. The remaining taxa have broader habitat preferences.

Index map shows location of study area and generalized path of the California Current, which moves south along the western coast of North America, from the vicinity of Vancouver Island, Canada, to southern Baja California, Mexico.
