The otter is a carnivorous animal, somewhat resembling the mink in appearance. They are found in various parts of the world and will be met with in most of the wilder parts of North America. The northern or Canadian otter is the most common, but there are other varieties known as the Carolina otter, the Florida otter and the Newfoundland otter. In habits and general appearance they are all similar.
A distinct species is found in the North Pacific, and is known as the sea otter. This animal is considerably larger than the fresh water species, and has a shorter tail. The fur is of great value.
The otter is an aquatic animal, living in and near the streams and lakes, and getting its living from them. It has a long body, short, stout legs, and webbed feet; the tail is long, thick at the base, and tapering to a point. The neck is thick, the head comparatively small, with small ears, set well down on the sides of the head. The fur is of two kinds, the under fur being fine, soft and wavy, and of a light silvery color; while the outer fur or guard hairs, are longer, coarser, and usually straight, the color varying from brown to almost black. The fur of the tail and under parts is shorter and stiffer than that on the back, sides and neck; that on the under parts having a silvery tint. Otters frequently measure three and one-half feet in length and weigh from fifteen to twenty-five pounds. The skin, when stretched, will often measure five feet from tip to tip, and sometimes even more.
The food of the otter consists principally of fish, trout being their favorite food; but they also feed on muskrats, clams, frogs, and the smaller animal life, found in the beds of streams and lakes.
They capture muskrats by entering their houses and their holes in the banks.
Otters usually make burrows in the banks of streams, lining the nest with leaves and grass. The entrances to these burrows are under the water and it is my belief that they inhabit them only during the breeding season. The young are born in April and May and there are from two to four in a litter.
The otter is a great traveler, following the lakes and water courses, sometimes going a distance of one hundred miles on a single trip. Apparently he is always in a great hurry to reach a certain place, some lake or pond, at which, having reached, he may remain for several months, and again he may leave immediately after his arrival.
Otters sometimes have slides on the banks of streams, down which they slide into the water, apparently for pastime. They also have landing places on the banks of streams and on logs projecting into the water, where they go to roll in the grass and leaves, or to lie in the sun. These places are seldom visited in the fall, but in the spring, they will land at almost every place as they come along.
In traveling, they usually follow the center of the stream, as they are more at home in the water than on land. In winter they travel under the ice, wherever the water is deep enough to allow of their passage. The otter's legs being very short, he has a peculiar method of traveling on the ice or snow. He throws himself forward, sliding on his belly, and by repeating the move in rapid succession, is enabled to get along at a surprising rate of speed.
Wherever there is a sharp bend in the stream, the otter will make a short cut across the point, and if the stream is traveled much, you will find a well-defined trail in such a place. Where two streams lie close together, they sometimes have a trail from one stream to another. Also wherever a long point of land projects into a lake, they are likely to have a trail across the point.
