Sperm whales are usually found in deep, off-shore waters, but may be seen closer to shore, in areas where the continental shelf is small and drops quickly to depths of 310 to 920 metres (1,020 to 3,020 ft). [11] Coastal areas with significant sperm whale populations include the Azores and Dominica. [142]
