Marine Mammals

Page 1

Several million years ago, the first animals moved from the sea to colonize the land. Eventually, worldwide changes in climate and geography convinced some of the mammals to move back to the sea. These animals have since evolved to be perfectly adapted to their environment. Most of these animals comprise a group known as the cetaceans, which includes the dolphins and whales. The other main group of marine mammals falls into the pinnipedia family, which includes the seals and sea lions. Breathing air and then diving, cetaceans can hold their breath for unimaginable lengths of time. They are peaceful animals, and they are quite intelligent. Some of the largest brains in the world of mammals are found in the oceans. These animals have exhibited remarkable abilities to communicate and learn. Their natural lives are spent in close family groups caring for their young and each other. Their songs can be heard echoing for miles beneath the waves. It is shameful to think that mankind hunted most of these magnificent animals to the brink of extinction. But today, under the protection of most of the world's governments, they are coming back. In marine parks around the world, their ambassadors are helping to save their kind by helping us to better understand them. Below is a listing of some of the world's more familiar marine mammals.

Atlantic Bottlenosed Dolphin (Tursiops melaena)
Atlantic Bottlenose Dolphin
(Tursiops melaena)

The bottlenose dolphin is perhaps the most familiar of the sea mammals. Their gentle nature has endeared them in our hearts. These highly social animals have actually been known to rescue humans from danger. They are intelligent creatures with a brain size similar to ours. Some scientists believe they are capable of complex communication skills.

Atlantic Spotted Dolphin (Stenella frontalis)

(Stenella frontalis)

The Atlantic spotted dolphin looks very similar to the bottlenose dolphin except for the noticeable body spots. They are generally somewhat smaller than their cousins. As with all dolphins they travel in close family groups called pods.

Pilot Whale (Globicephala melaena)
Pilot Whale
(Globicephala melaena)

The pilot whale is a small member of the whale family, averaging about 10 feet in length. They are perhaps better known for the mass strandings in which entire pods of these animals will beach themselves in an apparent attempt at suicide. This behavior has yet to be explained.

Killer Whale (Orcinus orca)
Killer Whale
(Orcinus orca)

The killer whale of Shamu and "Free Willy" fame is a highly intelligent and very sociable animal. It is a standard attraction at most marine parks. Pods of Orcas have been known to work together when hunting for food. They will even temporarily beach themselves to catch one of their favorite foods - the sea lion.

Humpback Whale (Megaptera novaeangliae)
Humpback Whale
(Megaptera novaeangliae)

The humpback whale is a large animal, growing to 60 feet in length. These magnificent animals were one hunted to the brink of extinction, but are now starting to make a comeback. They feed on plankton, and are perhaps best known for their enchanting song, which can be heard for hundreds of miles under the sea.
