Generic Dolphin Identification
Dolphins are a laterally compressed, fusiform shaped, fishes with a deeply forked caudal fin, and a long single dorsal fin that originates over the top of the head. They have a long anal fin that runs from about halfway through the dorsal fin, to the caudal peduncle. They can rapidly change colors between metallic greens, yellows, and blues, but these colors will quickly fade after death. Males develop large bony crests on top of their heads once mature, while females retain the juvenile head shape. There really are no other fishes in the ocean that can be confused with a dolphin, they are unique.
