Pacific
humpback dolphins can vary in color from yellow to pink
to almost white to medium grey; their bellies are usually
the lightest areas.
Like bottlenose dolphins, they have a long, slender
beaks which may get lighter as they get older. They
also have a broad-based dorsal fin that slopes backwards.
In some individuals the base can be more than one third
of their body length.
Those found in the west have a fatty hump which the
dorsal fin sits on, those in the east don't have a hump
and they can sometimes get confused with bottlenose
dolphins.
