Otter
A Otters have long, thin bodies and short legs ideal for pushing through dense undergrowth or hunting in tunnels. An adult male may be up to four feet long and weigh around 30 pounds. Females are typically smaller. The Eurasian otter has one of the smallest noses among otter species, with a distinctive shallow ‘W’ shape. The otter’s tail, often referred to as a rudder or stern, is thick at the base and tapers toward the tip, flattening out—this forms part of the propulsion system when swimming quickly underwater. Otter fur consists of two types of hair: stout guard hairs that form a waterproof outer layer and a dense, fine under-fur that functions like thermal underwear. This fur must be kept in good condition through regular grooming. Saltwater reduces the fur’s waterproofing and insulation qualities. That is why freshwater pools are important for coastal otters. After swimming, they wash off the salt in these pools and then rub themselves dry against vegetation. B Scent is important for hunting on land, for communication, and for detecting danger. An otter’s sense of smell is likely similar in sensitivity to that of a dog. Otters have small eyes and are probably short-sighted on
