Last among the members of the weasel tribe come the otters. These animals are specially formed for living in the water. The paws, for example, are very large and broad, and the toes are fastened together by means of a kind of web, like that on the foot of a swan or a duck, so that they form very useful paddles. Then the body is long, lithe, and almost snake-like, and the tail is so broad and flat that it serves as a capital rudder, and enables the animal to direct its course. The fur, too, consists of two coats of hair instead of only one; the outer, which is composed of long, stiff bristles, lying upon the inner like a very close thatch, and quite preventing water from passing through. So although an otter is dripping from head to foot when it comes out of the water, it never gets really wet. The animal is wonderfully active in the water, and can easily overtake and capture the swiftest of fishes. Sometimes it is very destructive, for when fishes are plentiful it becomes so dainty that it never eats its victims, but just takes a bite or two from the best part of the flesh at the back of the neck, and then leaves the rest of the body lying upon the ground. So fishermen are not at all fond of it, and kill it whenever they can. But sometimes, when the rivers are very low, or when the surface of the water is thickly covered with ice, the otters find it very difficult to obtain a sufficient supply of food. So they leave the streams and wander far inland, sometimes making their way into the farmyards, and feasting upon poultry, or even upon young pigs and lambs. But they only do this when they are in real danger of starvation, and always return to the river-banks as soon as they can. The home of the otter is generally situated beneath the spreading roots of a large tree on the bank of a stream. The animal does not dig a burrow if it can help it, but prefers to take advantage of some natural cleft in the ground, at the end of which it makes a nest of flags and rushes. In this nest from three to five little ones are brought up, and if you were to lie very quietly on the bank for some little time early on a warm spring morning, you would very likely see the mother otter playing with her little ones, or teaching them how to swim and to catch fish. The bite of the otter is very severe, and it is almost impossible to force the animal to loose its hold.
