Fraser's
dolphin calves are born with dull coloration, but as
they mature into adult animals they develop a more striking
appearance. The adult dolphins have blue-grey upper
sides, and are creamy white or pink on their belly and
throat. Some of them, especially the males, have a vivid
dark black lateral body stripe; the width and intensity
of the stripe is thought to increase with age. They
also have a dark blue/ grey line (or lines) running
from their beak to their flippers.
These dolphins have small pointed flippers and a small
dorsal fin in relation to their body size. They have
a well-defined but short beak
