Otter Reproduction
Otter Breeding and Reproduction
Otters are ready to reproduce when they are from 3 to 6 years of age. The season for mating
depends on the region where they live. If there Otters habitat is thriving with enough room for them and plenty of
food then they may mate more than once in a give season. The males are the ones that seek out the females when they
are ready to mate.
Otherwise the two sexes generally stay separated with the exception of the young males remaining with their
mother for a few years. While the males and the females don’t live in the same rafts, they don’t seem to show
aggression towards each other when their habitats overlap either.
Research shows that a female Otter may be ready to mate again as soon as she has a litter. However, they usually
won’t in order to continue caring for the offspring they already have. Should a mother lose her pup though she will
have the desire to mate again very soon as long as she isn’t living under stressful conditions.
The males will start showing up in the areas where the females have territory during the mating season. However,
the approval for the mating to take place is given by the female. If a male doesn’t get the warm reception he was
looking for from a female he will move on to find another one.
One way that females show their interest is by rolling around with the male. This type of playful activity is
one that will also increase her level of hormones being released. She may also bite the nose of the male as a way
to say she is interested. This type of courting takes place on land. However, for the actual mating process the
Otters move into the water.
It takes from 5 to 8 months from conception to the time when they pups will be born. Only one pup will be born
at a time. They are generally born from May through July. They young will feed from their mother for about the
first 12 months of life. Some species are weaned earlier though at about 8 months of life. Sea Otters can have up
to four pups at a time and that means they will nurse them for a shorter period of time.
The pups are born in the water on a bed of kelp or in the den. If they are born on land then they are moved to
the den by the mother. The pups are very helpless at birth as they are blind until they are about a month old. They
will stay inside of the den until they are able to see. Then they will be led to the water by the mother to learn
how to swim.
The females are very good caregivers to their offspring. They may spend up to 8 hours each day just nursing
them. These young Otters consume a great deal of milk each day in order to grow rapidly. They are also seen playing
with their offspring, teaching them valuable skills, and protecting them with their own life.
When the pups are about four months old they will be introduced to solid foods. They will learn the basics of
how to hunt for food on land in and the water by their mother. Even with the excellent care provided, pups are very
vulnerable during the first year of life. Approximately 32% of them won’t live to be a year old. Statistics also
show that less than 25% of the females live to maturity in order to mate.
