There is nothing cuter than a River Otter. However, they are excellent predators – speeding under the water just like a torpedo. A fish doesn’t stand a chance. Otters are one of the larger members of the Weasel family – 28” from nose to tail tip. Weasels are mustelines. All mustelines give off a protective odor (i.e. skunks).
Otters are very active and many of their actions appear to be play. Sliding down river banks seems to be a favorite activity. They are semi-aquatic and move well on land (up to 18 mph), as well as in the water. Their long tail and webbed feet are a great aid in their under water navigation. Thick, dense fur keeps them well insulated from the cold and those prominent whiskers are sensitive to surrounding situations.
Fish is their main food source but they will also consume frogs, crustaceans, insects, and occasionally water fowl and small mammals. They den on land and the female evicts the male before birthing. He will return when the young are half grown and help in their care. Their lifespan is usually 10 to 15 years.
On two successive and very chilly mornings, at South Davis Lake, Oregon, we pursued a family of three. It was September and the mornings were cold in the woods. My fingers were so cold that it was difficult to work the camera. However, the cold was overlooked because we were experiencing a rare (for us) event. Following that family group up and down the stream, as they sped after trout, kept us at rapt attention – from just before sunrise to about 11:00 AM each day. Those mornings provided golden opportunities to observe and photograph these lovable creatures.
