I think we can consider the whale an animal of a roving disposition. In early times it roved away from land, and now it belongs to the migratory animals, changing its locality with the seasons. The Greenland Whale is happiest with cold and ice, so when summer comes it travels north in great numbers. These great groups are called schools, and being of a social disposition, it is seldom found alone when traveling. At first thought it would seem strange that a warm-blooded animal with no fur to protect it could so enjoy the cold, but should we examine beneath the soft, velvety skin we would find a great layer of fat, from ten to eighteen inches thick. This protects the animal from cold like a great soft overcoat, and the polar sea has for it no terrors. Of the peculiar make-up of the Greenland Whale the head is certainly the most peculiar of all the parts. It is a great, shapeless mass about a third of the length of the entire animal. It seems to be out of all proportion until one realizes that it must provide food for this great creature, which is no small task. Like all of the whalebone whales, the Greenland Whale has no teeth, but in the mouth is found a great number of flexible, bone-like appendages attached to the roof of the mouth and palate at one end and hanging loose at the opposite end. These are known as the baleen plates and form the whalebone of commerce. In the Greenland Whale this whalebone hanging from the center of the jaw is sometimes twelve feet in length, and as there are from two hundred and fifty to four hundred in number, the great value of the baleen is readily seen. When the great animal opens its mouth, a row boat with its oarsmen could easily be taken in, yet the animal eats only small crustaceans, mollusks, worms and minute forms of life. When the immense mouth opens, it takes in a large amount of water containing its food. The mouth then closes, but the water is permitted to flow out, the baleen acting like a sieve, retaining the food supply within and allowing the water to ooze away. The food is retained on the great tongue and swallowed at leisure. The eye of the whale is very small; the ear is barely perceptible, yet when submerged, the sight is keen and the hearing well developed. The nostrils are placed on the top of the head, so that the whale when rising can readily begin the operation of breathing. With a snorting noise the animal first blows up the water which has entered the imperfectly closed nostrils when submerged. This is done with such force that the water is separated into fine drops and thrown fifteen or eighteen feet into the air. The whale then breathes with a rapid inspiration, making a sort of moaning sound. When the lungs are filled with air, it will plunge beneath the surface of the water and remain for perhaps twenty minutes before appearing again, although when wounded it remains under water a much longer time.
