【蓝鲸的英文介绍】
【Animal Classification】
Blue Whale (Balaenoptera musculus)
【Description】
It is difficult to imagine the size of the blue whale, the largest animal inhabiting the earth. There are records of indivials over 100 feet (30.5 m) long, but 70-90 feet (23-27 m) is probably average. A good way to visualize their length is to remember that they are about as long as three school buses. An average weight for an alt is 200,000 to 300,000 pounds (100-150 tons). Its heart alone is as large as a small car. Blue whales are an overall blue-gray color, mottled with light gray. Cold water diatoms adhere to their skin and sometimes give their bellies a yellowish tinge, giving the blue whale its nickname of "sulfur bottom." Blue whales are long and streamlined. Their dorsal fins are extremely small, and their pectoral flippers are long and thin. Blue whales are rorqual whales, a family of baleen whales with pleated throat grooves that expand when the animal takes in water while feeding. In blue whales, 55-68 throat grooves extend from the throat to the navel. Blue whale baleen is black with over 800 plates.
【Range/Habitat】
Blue whales have been found in every ocean of the world. Blue whales swim indivially or in small groups. Pairs are very commonly seen. Approximately 2,000 blue whales live off the California Coast and migrate to Mexico and Costa Rica.
【Mating/Breeding】
Females give birth to calves every two to three years. They remain pregnant for about one year before giving birth. When born, the blue whale calf is about 23 feet (7 m) long and weighs 5,000 to 6,000 pounds (2,267 to 2,722 kg). A nursing blue whale mother proces over 50 gallons (200 liters) of milk a day. The milk contains 35 to 50% milk fat and allows the calf to gain weight at a rate of up to 10 pounds an hour or over 250 pounds (113 kg) a day! At six months of age and an average length of over 52 feet (16 m), the calf is weaned. The blue whale reaches sexual maturity at around 10 years of age.
【Behavior】
The favorite food of these giants is krill, or shrimp-like euphausiids, that are up to three inches long. Blue whales must eat two to four tons of krill a day ring the feeding season. They concentrate on feeding ring the polar summers primarily around the Channel Islands, Monterey Bay, and the Farallon Islands/Cordell Bank. During the winter months, they migrate to the warmer waters in Mexico and Costa Rica.
【Status】
The blue whale was too swift and powerful for the 19th century whalers to hunt, but with the arrival of harpoon cannons, they became a much sought after species for their large amounts of blubber. The killing reached a peak in 1931 when 29,649 blue whales were taken. By 1966, blues were so scarce that the International Whaling Commission declared them protected throughout the world. Today, there are between 8,000-9,000 blue whales in the oceans, and they are considered an endangered species. However, we can see them in the summer and fall off the central California coast, feeding in such places as the Gulf of the Farallones and Cordell Bank National Marine Sanctuaries. The 2,800 blue whales that feed along the California coast make up the largest concentration of blue whales in the world.

1、The blue whale is the largest animal ever to inhabit the Earth.Blue whales are found throughout the world's oceans. These gentle giants have grayish-blue skin with light spots. Measuring 70 to 80 feet in length, blue whales can weigh as much as 90 to 150 tons, although females are larger than the males.

2、
The blue whale is the largest mammal, possibly the largest animal, to ever inhabit the earth. Its body is long, somewhat tapered, and streamlined, with the head making up less than one-fourth of its total body length. Its rostrum (upper part of the head) is very broad and flat and almost U-shaped, with a single ridge that extends just forward of the blowholes to the tip of the snout. Its blowholes are contained in a large, raised "splash guard", and the blow is tall and straight and over 20 feet (6 meters) high. Its body is smooth and relatively free of parasites, but a few barnacles attach themselves to the edge of the fluke and occasionally to the tips of the flippers and to the dorsal fin. There are 55-68 ventral grooves or pleats extending from the lower jaw to near the navel.
