Baby Otters

An otter's den is called a holt or couch. A male otter is a dog, a female a bitch, and a baby a whelp, kit, or pup. The collective nouns for otters are bevy, family, lodge or romp, being descriptive of their often playful nature, or when in water raft.
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 that it can learn and be kept safe until maturity. Otters live up to 16 years.
