　　英文原文阅读　　Life cycle

　　The time of gestation in otters is about 60 to 86 days. The newborn pup is taken care of by the mother, the father, and all the other offspring. Female otters reach sexual maturity at approximately two years of age, while males can produce offspring at approximately three years of age. After one month, the young otter can come out of the cave and, after two months, it is able to swim. It lives with its family for about one year, so it can learn and be kept safe until maturity. Otters live up to 16 years.

　　Characteristics

　　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 13 species range in adult size from 0.6 to 1.8 metres (2 to 6 ft) in length and 1 to 45 kilograms (2.2 to 100 lb) in weight. The Oriental small-clawed otter is the smallest otter species and the giant otter and sea otter are the largest. They have very soft, insulated underfur, which is protected by an outer layer of long guard hair. This traps a layer of air, and keeps them dry and warm under water.

　　Many otters live in cold waters and have very high metabolic rates to help keep them warm. European otters must eat 15% of their body weight a day, and sea otters 20 to 25%, depending on the temperature. In water as warm as 10 °C (50 °F), an otter needs to catch 100 grams (3.5 ounces) of fish per hour to survive. Most species hunt for three to five hours a day, and nursing mothers up to eight hours a day.

　　For most otters, fish is the staple of their diet. This is often supplemented by frogs, crayfish and crabs.[3] Some otters are expert at opening shellfish, and others will feed on available small mammals or birds. Prey-dependence leaves otters very vulnerable to prey depletion.

　　Otters are very active, chasing prey in the water or searching the beds of rivers, lakes or the seas. Most species live beside water, but river otters usually enter it only to hunt or travel, otherwise spending much of their time on land to avoid their fur becoming waterlogged. Sea otters are highly aquatic and live in the ocean for most of their lives.

　　Otters are playful animals and appear to engage in various behaviors for sheer enjoyment. Different species vary in their social structure, with some being largely solitary, while others live in groups – in a few species these groups may be fairly large.
