The winners in life's race

by Arabella B. Buckley

Even the polar bear, living amidst perpetual snow and ice on the shores of Spitzbergen, Nova Zembla, and Greenland, has not, on the whole, a bad life of it, for he is master of the situation, and conquers and devours even the tusked walrus. The polar bear is a most interesting animal, because he shows us the bear tribe becoming adapted to a watery life. His body is much longer and more flexible than that of most bears, giving him the power to twist and turn in the water, as he swims with strong broad feet; and his long neck, narrow head, and small ears, are all fitted for a watery fishing life, while he fights entirely with his teeth and does not hug his prey. Again, the soles of his feet, instead of being bare, are covered with long stout hairs, giving him foothold upon the slippery ice, over which he travels very quickly, climbing up from time to time on the icy hummocks to see where seals are to be found, or to scent a dead whale from afar. He is an inveterate seal-hunter, chasing them in the water or out of it with equal ease and great cunning, though they are quick too, and often escape him just when he thinks he has caught them. It is when they are asleep with their noses upon the ice or the land, that he has his best chance, for then he will swim warily behind them, coming up close, till, even if they wake, they have no choice but to be killed where they are, or to leap out on the solid ice where he will soon overtake them.

The polar bear, unlike his brown cousins, fishes and hunts all the winter through, and it is only the mothers which take refuge in caves hollowed out of the snow, where their little ones are born in early spring, and nestle down by her side in their icy home. And when the cubs can run, both father and mother care for them with true devotion, defending them against all attacks, and pushing them before them when pursued, even going so far as to take them in their teeth and swim away with them when they cannot otherwise save them.

So we see that the polar bear has become more than half a water-animal, and gives us the first hint that some milk-givers may take to a thoroughly sea life. Neither among the wolves nor the felines do we find any animals taking entirely to the water; but in the weasel family, which comes near to the bears, we have the otters, and among the bears themselves their polar cousin, which reminds us that there is another great division of flesh-feeders which we must study in the next chapter—the walruses, seals, and sea-bears, the porpoises, dolphins, and whales, which with finned paddles have struck out quite a new line of life, and imitated the fish so well that they are often wrongly classed among them.

EUROPE IN THE AGE OF ICE

CHAPTER XI.
HOW THE BACKBONED ANIMALS HAVE RETURNED TO THE WATER, AND LARGE MILK-GIVERS IMITATE THE FISH.

“On revient toujours à ses premiers amours,” says the French song. But who would have thought that, after rising step by step above the fish, and tracing the history of the backboned animals through their development in the air and over the land, till we brought them to a stage of intelligence second only to man, we should have to follow them back again to the water and find the highly gifted milk-givers taking on the form and appearance of fishes? Nevertheless it is so, for seals and whales are as truly flesh-eating milk-givers as bears and wolves; nor are they much behind them in intelligence, for we all know how teachable and affectionate seals and sea-lions are, while what little is known of the life of whales shows that they are devoted mothers, and their well convoluted though small brains are a proof that they are by no means wanting in intelligence.

Yet the whales and dolphins, at any rate, have not only adopted a sea life, but have limbs so like a fish’s fins that we can scarcely call them by any other name, and they are so completely water animals that they cannot even return to the land.

Now we should be quite puzzled to account for such curious forms as these warm-blooded animals, half transformed into fish, if it were not that we know of several land animals belonging to different groups which have gone part of the way towards a fish life. Thus among the reptiles we have the oceanic turtles and the sea snakes; among birds the penguins, whose wings have almost become fins. Then among the milk-givers we have the web-footed Duck-billed Platypus, the Yapock or web-footed opossum of South America, the Desman and the Beaver, the Polar Bear, and last but not least the Otters, web-footed animals nearly allied to the weasels, which seek their food entirely in the water.

The common Otter of Europe and America though he moves quickly and actively on land, has webbed toes with only short claws standing out beyond the swimming foot, and he spends the greater part of his life in the river, making his home in a hollow of the bank beneath the overhanging roots of trees. There he may still be seen in many of our English rivers, his soft brown fur shining as he swims along, diving under water for a fish, which he brings out on to the bank to eat, holding it in his fore paws.
