Habitat and range
Atlantic sea scallops live on marine seabeds from eastern Canada towards the eastern United States. Depth and suitable bottom conditions vary across this range.
Appearance and adaptations
Two broad shell valves enclose the animal, with one valve more curved than the other. The mantle fringe bears sensory structures around the shell opening.
Diet and behaviour
The gills gather suspended food from seawater. Shell closure can expel water and propel the scallop away from a threat, although much time is spent resting on the seabed.
