Whales

Whale weighs as much as 20 elephants but lives beneath the sea. The blue
whale is Earth's largest animal. Larger than the largest of ancient
dinosaurs, blue whales can grow to be more than 100 feet (30 meters) long
and weigh nearly 150 tons. Not all whales are so large. The much smaller
pilot whale grows to about 28 feet (8.5 meters) in length. And dolphins,
which belong to the whale family, range only from 3 to 13 feet (1 to 4
meters). Although whales spend their lives in the sea, they are, like
humans, warm-blooded mammals. After a baby whale is born, it nurses on its
mother's milk, just like the young of land mammals.
Whales are members of the order Cetacea, along with dolphins, porpoises, and
the narwhal. There are two basic types of living cetaceans: baleen, or
whalebone, whales of the scientific suborder Mysticeti; and toothed whales
of the suborder Odontoceti.
General Characteristics
Whales live in all of the open seas of the world, though some occasionally
enter coastal waters. Some species, such as the white whale, or beluga, may
travel upstream in large rivers. Some species migrate with the seasons;
others remain year-round in the same habitats, where they find their
preferred food.
The present-day distribution and abundance of some species has been greatly
influenced by the commercial whaling industry. Whalers eliminated or greatly
reduced the numbers of some species of baleen whales in certain oceanic
regions where whales once frolicked in abundance. This is particularly true
in parts of the Arctic Ocean and the eastern North Atlantic Ocean, where the
blue whale was almost completely exterminated in the early 1900s. Some
species of whales, however, are numerous today in the Arctic and Antarctic
regions.
The skin of whales is usually black, gray, black and white, or all white.
Some, such as the blue whale, have skin that is bluish-gray. The surface of
the skin is smooth, but like other mammals, whales have hair. Hair first
appears while the fetal whale is still developing inside its mother's womb.
In adult whales, hair is confined primarily to a few bristles in the head
region and is largely absent over most of the body. Whales that live in
polar regions are insulated from the extreme cold by a layer of blubber, or
fat, enveloping their bodies.
Baleen Whales

The baleen whales include the family of right whales, Balaenidae, so named
because whalers considered them "just right" easy to kill and full of oil
