"The Clymene dolphin is distinguished from the very similar spinner dolphin by the shortness of its beak and its color pattern. Like spinners, they ""spin,"" leaping high out the water and rotating (not a somersault, but a sideways roll) several times before splashing back into the water. Clymene dolphins feed on deep-water fish and squid, and except for stranded individuals, have only been seen in deep water. Sharks and large toothed whales such as killer whales, pygmy killer whales, and false killer whales probably prey on them. Often the dolphins have small white marks on their skin that are healed shark bites. The species was first mentioned to in scientific literature with the description of a skull in the 19th century. No one was able to describe the Clymene dolphin scientifically until the 1970s, when some of them stranded in Texas and New Jersey."
