Dolphin Anatomy Terms

Blowhole - The opening at the top of the dolphin's head where air enters the dolphin and waste gases are expelled. The blowhole connects by tubes to the lungs. Breathing does occur through the mouth as well as the nose as it does in many other mammals, including humans.
Dorsal fin - the fin on the back of the dolphin that can often be used for identification purposes. The leading edge of the dorsal fin is that portion toward the head end of the dolphin and the trailing edge is that part that is toward the tail (fluke) of the dolphin. Leading edge scars and cuts are often caused by fishing nets; other nets or fishing line that may be free floating or tangled around submerged objects; boat propellers, and; encounters with each other and other marine animals. Trailing edge scars and cuts may occur from the same reasons as leading edge cuts and scars but are more often the result of encounters with other dolphins and marine animals over time.

Pectoral Fins - there are two side flippers toward the front, underside of the dolphin that aid in maneuvering and balance in the water.

Fluke - The tail fin of the dolphin that is the principal means of propulsion through the water. The fluke is controlled by powerful sets of muscles.

Melon - A large mound on the dolphin's forehead that is an integral part of its echolocation system. The melon is relatively soft and contains mostly fatty tissue.
