), but it is smaller in size and more robust in build. Clymene Dolphins have moderately sized, falcate dorsal fin and slender, curved flippers. Color pattern is three-toned and comprises a dark-gray dorsal cape, pale-gray flanks, and white-pink belly, throat, and lower jaw. Dorsal cape dips above eye to cover most of melon, and dips again at mid-body below dorsal fin. Lips and beak tip are black or dark gray. There is dark stripe extending longitudinally from beak tip to base of melon, and there are dark streaks running across beak like a moustache. Dark ring encircles eye, and dark band from corner of eye extends posteroventrally to leading edge of flipper joint. There are 39-52 pairs of conical teeth in each upper jaw and 39-48 pairs in lower jaw.

Prefers deeper offshore waters with an average depth of 1870 m. The Clymene Dolphin has different distributional extensions on each side of the Atlantic Ocean. Northern limit is ¢.39° N in the western Atlantic Ocean and c.16° N in the eastern Atlantic Ocean. Southern limit is ¢.30° S in the western Atlantic Ocean and c.7° Sin the eastern Atlantic Ocean.

Little is known about the diet and preferred prey of the Clymene Dolphin. It appears to be primarily a nocturnal feeder, which is supported by analyses of stomach contents that contain small mesopelagic fish and squid species that are known to be associated with the deep scattering layer. These prey include lanternfish (myctophids), herring smelts (argentinids), and codlets (bregmacerotids). The Clymene Dolphin herds schools of fish by hunting cooperatively during the day in the Gulf of Mexico. This suggests that it has an opportunistic diet that varies geographically and by prey availability.

The Clymene Dolphin is aerially active and is known to spin on its long axis like the Spinner Dolphin, although with fewer revolutions perjump and less elaborate acrobatics. They are also known to bow-ride.

The Clymene Dolphin generally lives in small groups consisting of one to several tens of individuals. Average group size is ¢.70 individuals, but groups of up to 1000 individuals have been observed. In the Gulf of Mexico, group sizes are usually less than 200 individuals, and the largest groups tend to have 60-80 individuals. Sex and age classes may segregate within groups, and adult males tend not to travel in groups with mother—offspring pairs. The Clymene Dolphin is often observed in groups or in close association with Spinner Dolphins. They are also observed in groups with Short-beaked Common Dolphins (

CITES Appendix II. Classified as Data Deficient on The IUCN Red List. In the northern Gulf of Mexico, there are ¢.6575 individuals, and off the east coast of the USA, there are ¢.6086 individuals. There are no estimates for total abundance or population trends. The Clymene Dolphin is occasionally taken as direct catch in dolphin harpoon fisheries in the Caribbean (e.g. St. Vincent and the Grenadines), and incidental captures occur occasionally throughout most ofits distribution. Off Brazil and Venezuela, the Clymene Dolphin is susceptible to gillnet fisheries. Incidentally caught corpses are used for shark bait and human consumption. There is no conclusive evidence on whether any of these catches are actually intentional. Overall, exploitation does not appear to be a major threat to the Clymene Dolphin. Several species of ocean dolphins, including the Clymene Dolphin, may be taken in large numbers in tuna purse-seine fisheries off western Africa, but there is currently no monitoring there.
