Some Facts About Whales
Suborder Mysticeti -- Baleen Whales
Suborder Mysticeti -- Baleen Whales
have hundreds of thin plates in the mouth which they use to strain out food from the water. They feed mainly on plankton.
Suborder Odontoceti -- Toothed Whales
Suborder Odontoceti -- Toothed Whales
differ greatly in size, shape, and the number of teeth they have. Some toothed whales eat fish, and others eat such animals as cuttlefish and squid.
Blue Whale (Balaenoptera musculus)
The Blue Whale (Balaenoptera musculus)
is the largest animal to have ever lived, dwarfing even the largest dinosaurs. Adults average 80 to 105 feet in length and weigh up to 200 tons. The tongue is as heavy as an elephant, and the heart the size of an automobile.
Beluga Whale (Delphinapterus leucas)
Beluga Whale (Delphinapterus leucas)
This whale's common name comes from the Russian word for "white," which is very appropriate since it is the only all-white whale in the world. It is also one of the most vocal whales, with a voice that has led to it sometimes being called a "sea canary."
Gray Whale (Eschricktius robustus)
The Gray Whale (Eschricktius robustus)
has one of the longest migrations of all mammals -- 10,000 to 14,000 miles between their feeding and calving grounds, round trip. Unlike other baleen whales, the gray whale is a bottom feeder.
Narwhal (Monodon monoceros)
Narwhal (Monodon monoceros)
The most characteristic feature of the narwhal is its tusk, which is always spiral in a counter-clockwise (as viewed by the animal) direction and can be as long as 9 feet. Only present in males, the tusk is actually a greatly elongated tooth.
Humpback Whale (Megaptera novaeangliae)
The
Humpback Whale (Megaptera novaeangliae)
is one of the largest baleen whales, with adults being 40-50 feet long and weighing 25-40 tons. It is distinguished from other whales by an obvious hump behind the head, black dorsal coloring, wavy rear edges on the tail flukes, and the presence of rounded, bump-like knobs on the top of the head.
Bottle-Nosed Dolphin (Tursiops truncatus)
Bottle-Nosed Dolphin (Tursiops truncatus)
The most distinguishing feature of the bottle-nosed dolphin is its short, thick beak with 20-28 sharp conical teeth on each side of the jaw, giving it a "smiling face." Among the most intelligent and playful animals in the sea, they are star attractions at marine parks around the world and one even starred in a television series.
