ORDER V.
Whales and Dolphins. This order is divided into two sub-orders, the one characterised by the possession of teeth, and the other being toothless.
The Right Whale. The Right Whale when fully grown, attains to from fifty to sixty-five feet in length, and to from thirty to forty feet in circumference. It is thickest behind the fins. When the mouth is open, it presents a cavity as large as a room, and capable of containing a boat full of men. Its tongue is said to be as large as a stout feather-bed. The tail is a powerful instrument of motion and defence: it is only five or six feet long, but its motions are rapid, and its strength immense. The eyes are situated in the sides of the head; they are very small, being little larger than those of an ox. The whale has no external ear, but there is a small orifice under the skin for the admission of sound. On the most elevated part of the head are two blow holes six or eight inches in length. The mouth, instead of teeth, has two rows of whalebone, each of which contains more than three hundred laminae, the longest of which are about ten or eleven feet. A large whale sometimes contains a ton and a half of whalebone. The colour of the old whale is gray and white, that of the young ones a sort of bluish black. Immediately beneath the skin lies the blubber, or fat; its thickness round the body is eight or ten or twenty inches, varying in different parts: the lips are composed almost entirely of blubber. A large whale yields about twenty tons of oil, which is expressed from the blubber. It is for this and the whalebone that this animal is deemed so valuable, and for which it is so much sought by whalefishers. The sense of seeing in the whale is very acute. Under the surface of the water they discover one another at an amazing distance. They have no voice, but in breathing or blowing they make a loud noise.
The usual rate at which whales swim seldom exceeds four miles an hour, but for a few minutes at a time they are capable of darting through the water with amazing velocity, and of ascending with such rapidity as to leap above the surface. This feat they perform as an amusement, apparently to the high admiration of distant spectators. Sometimes they throw themselves in a perpendicular posture, with the head downwards, and rearing their tails on high, beat the water with awful violence. Sometimes they shake their tails in the air, which, cracking like a whip, resound to the distance of two or three miles. The flesh of the whale, though it would be rejected by the dainty palates of refined nations, is eaten with much relish by the Eskimo, and the inhabitants along the coasts of Hudson's Bay and Davis's Straits, who esteem it a staple article of subsistence.
Other whales of this sub-order are the common Fin Whale, which is said to reach eighty feet in length, the lesser Fin Whale and the Humpback Whale. In these, the yield of whalebone and oil is so small that they are not thought worth the trouble of catching.
The Sperm Whale. The Sperm Whale rarely exceeds sixty feet in length and lives in warm regions, such as the Indian Ocean; rarely, if ever, visiting Arctic or European seas. Its yield of oil is said to be less than that of the Greenland whale but it is of a finer quality. Ambergris is also produced from the body of the sperm whale.
The Dolphin. This is a large creature, so like the porpoise that he has been often confounded with it. He is, however, much larger, sometimes measuring from twenty to twenty-five feet in length. The body is roundish, growing gradually less towards the tail; the nose is long and pointed, the skin smooth, the back black or dusky blue, becoming white towards the belly. He is entirely destitute of gills, or any similar aperture, but respires and also spouts water through a pipe of semi-circular form placed on the upper part of the head. There are several varieties of dolphins, including the Long-nosed Dolphins of the rivers of Asia and South America and the Classical Dolphin of the Mediterranean (Delphinus delphis) The former are separately classified, and the family of the latter includes the White Whale, the Narwhal, the Common Porpoise and the Grampus. The dolphin is gregarious in its habits, herding and travelling in large shoals. It may sometimes be seen sporting in the bays and rivers of New York and is always a pretty sight.
The White Whale. The White Whale (Beluga catodon) is the whale which Dr. R. Brown calls the whale of Greenland. It is the whale which the Greenlander and the Eskimo find so valuable for its oil and flesh, the latter of which they dry for winter use. They are sometimes called sea pigs, from a fancied resemblance they bear to the pig when floundering in the sea, and sometimes sea canaries, on account of their peculiar whistle, which resembles that of a bird.
The Narwhal. The narwhal (Monodon monoceros) is found frequently in company with the white whale, and inhabits much the same geographical area. It is distinguished by the possession of a tusk, the aim and purpose of which has been much debated. "It has been supposed to use it," says Dr. Brown, "to stir up its food from the bottom, but in such a case the female would be sadly at a loss. Fabricius thought that it was to keep the holes open in the ice during the winter; and the following occurrence seems to support this view. In April, 1860, a Greenlander was travelling along the ice in the vicinity of Christianshaab, and discovered one of those open spaces in the ice, which, even in the most severe winters, remain open. In this hole hundreds of narwhals and white whales were protruding their heads to breathe, no other place presenting itself for miles around. It was described to me as an Arctic 'Black Hole of Calcutta' in the eagerness of the animals to keep at the place." "Neither the narwhal nor the white whale," he continues, are timid animals, but will approach close to, and gambol for hours in the immediate vicinity of the ship." The oil is highly esteemed, and the flesh is very palatable. The skin of the narwhal boiled to a jelly is looked upon, and justly so, as one of the prime dainties of a Greenlander.
The Common Porpoise. The Porpoise resembles the dolphin in general appearance. Its length, from the tip of the snout to the end of the tail, is from five to eight feet; and the width about two feet and a half. The figure of the whole body is conical; the colour of the back is deep blue, inclining to shining black; the sides are gray, and the belly white. When the flesh is cut up, it looks very much like pork; but, although it was once considered a sumptuous article of food, and is said to have been occasionally introduced at the tables of the old English nobility, it certainly has a disagreeable flavour. Their motion in the water is a kind of circular leap; they dive deep, but soon again rise up in order to breathe. They are seen in nearly all seas, where they sport with great activity, chiefly on the approach of a squall.
The Grampus. The Grampus (Orca Gladiator) is the natural enemy of the whale and the seal, who hold him in mortal terror. His swallow is so great that he can take a porpoise or a seal whole, and has been known to swallow several in succession. The whale escapes him by getting among the ice, whither it is said the grampus will not follow him.
