Of all the dolphins I love, the Atlantic White Sided is my favorite. They are one of the smallest. But, in my opinion, they are the smartest, funniest, and most lovable dolphins in the world. They are black with dark grey flanks. They have a long white oval below the dorsal fin. There is a yellow-ochre band across its tail. Black rings go around the eyes, thick tail. The population can not even be estimated though many believe the species population is abundant. Actually, the population is about 40% the size of the white beaked dolphins. Atlantic White Sided dolphins have a wide variety of prey. The main foods are squid, smelt, herring, and silver hake. Also the occasional shrimp.
