Underwater television, remote photography and SCUBA diving have revealed that Clyde Sea Area sublittoral muds are extensively bioturbated by megafaunal species that construct conspicuous burrows. These species arc mainly decapod crustaceans and fish, each with a characteristic burrow configuration and optimum horizon for excavation. Burrow structures have been revealed by resin casting and densities and distributions have been studied using camera and SCUBA techniques. Burrowing behaviour has been investigated by field and laboratory studies, while physiological studies of some species have shown respiratory adaptations to the burrowing mode of life. Megafaunal burrowing appears to be an important determinant of benthic community structure.
