Dorsal

The Dorsal or Dorsal fin
is located on the back of the
cetacean. They can be many shapes:
pointy, round, triangular or curved.
Some cetaceans lack a Dorsal fin.

Pectoral(s)

The paired Pectoral Fins are located
on each side of the cetacean and are
used for steering.

Fluke(s)

The Fluke or Tailfluke of a
cetacean is attached to the tail
and used to make speed through the water.

Melon

The Melon is the 'forehead' of
the cetacean that contains a
thick oil-like fluid

Rostrum

The Rostrum is also known
as the snout or beak of a cetacean.

Blowhole

The Blowhole (or in some cases
Blowholes) is located on the top
of the cetaceans head.
It is the only way to breathe air
Cetaceans can not breathe through their
mouth. Water does not come out
of the blowhole. The spray that cetaceans
create while breathing is simply vapor,
sometimes a little amount of oil-like substance
from the blowhole, and water that was on top
of the blowhole being spouted through the air.
