The Spinner Dolphin is dark gray, with darker patches in the
tail stock, back and throat. Usually it has creamy-white patch on
the belly though this varies considerably. The beak is distinctively
long and thin, with a dark tip. The fins too are lengthy for
dolphins of this size. The dorsal fin is erect and even leans
forward in older males found in the eastern Pacific. However
this description has to be described as a little loose -
Spinner Dolphins are the most variable in form of all cetaceans.

The Dwarf Spinner Dolphin was only recently discovered
in the Gulf of Thailand. It has a very bright yellow patch
and slate gray back.
