Abstract

Major variations in lipid composition exist within the fatty melon tissue of the Atlantic bottlenosed dolphin Tursiops truncatus. Topographical lipid analyses indicate a central “inner melon” core surrounded by distinctive “outer melon”, “under melon”, and blubber tissues. Acoustical considerations suggest that this melon-lipid topography may aid in collimation of the ultrasonic pulses used by the dolphin for echolocation.
