The Greatest Mystery of Whales

? ?The whale is a mammal(哺乳动物) warm-blooded, air-breathing, giving birth to its young alive, sucking them—and, like all mammals, originated on land. There are many signs of this.
? ?{{U}} ?(51) ?{{/U}} front flippers (鳍肢), used for steering and stability, are traces of feet.
? ?Immense strength is built into the great body of the big whales, and in fact most of a whale’s body is one gigantic muscle. The blue whale’s pulling {{U}}?(52) ?{{/U}} has been estimated at 400 horsepower. One specimen was reported to have {{U}}?(53) ?{{/U}} a whaling vessel for seven hours at the {{U}}?(54) ?{{/U}} of eight knots.
? ?An enraged whale will attack a ship. A famous {{U}}?(55) ?{{/U}} of this was the fate of whaler Essex, which was sunk {{U}}?(56) ?{{/U}} the coast of South America early in the last century. More recently, steel ships have had their plates buckled (扭曲变形) in the same way. Sperm whales were known to {{U}}?(57) ?{{/U}} the old-time whaleboats in their jaws and crush them.
? ?The greatest mystery of whales is their diving ability. The sperm whale can {{U}}?(58) ?{{/U}} the bottom for his favorite food, the octopus (章鱼). {{U}}?(59) ?{{/U}} that search he is known to go as far down as 3,200 feet, where the pressure is 1,400 pounds, to the square inch. Doing {{U}}?(60) ?{{/U}} he will remain submerged (水下的) as long as one hour. Two feats (绝技) are involved in this: storing up enough {{U}}?(61) ?{{/U}} (all whales are air-breathed) and withstanding the great change in pressure. Just {{U}}?(62) ?{{/U}} he does it scientists have not determined. It is believed that some of the oxygen is stored in a special system of blood vessels, rather than just held in the lungs. And {{U}}?(63) ?{{/U}} is believed that a special kind of oil in his head is some sort of compensating mechanism that automatically adjusts the internal pressure of his body. But {{U}}?(64) ?{{/U}} you can’t bring a live whale into the laboratory for study, no one {{U}}?(65) ?{{/U}} just how these things work.
