You Otter Know
Rivers otters are mostly solitary (live alone), except for females with their young.
Otters come together during the mating season in late winter or early spring.
Females give birth to 1 to 6 young per litter, with an average of 2 to 3.
Otters are born with fur, but are otherwise helpless.
Females give birth, nurse, and care for their young in a den near the water. The young are weaned at about 3 months old and begin to leave their mother at 6 months old. Adult females care for their juvenile offspring, who disperse by the time the otters give birth again. River otter become mature at 2 to 3 years old.
