MADISON (WKOW)-- The Henry Vilas Zoo has tons of exotic animals for you to see every day. Perhaps some of the most exciting and fun animals to check out are the lovable and energetic otters!
Otters are semi-aquatic mammals. Otters have an almost worldwide distribution. They mainly eat aquatic animals, predominantly fish and shellfish. Otters have long, slim bodies and relatively short limbs, with webbed paws. Most have sharp claws on their feet, and all except the sea otter have long muscular tails. The twelve species range in adult size from 0.7 to 1.8 met res (2 to 6 feet) in length and 5 to 45 kilograms (11 to 100 pounds) in weight. They have a very soft, insulated underfur which is protected by their outer layer of long guard hair. This traps a layer of air, and keeps them dry and warm under water.
Most of all, otters are just plain fun to watch swim around. You can check them out at the Zoo and you can learn more about them at http://www.vilaszoo.org.
