Sea otters are polygynous, with males having multiple female partners throughout the year.

Sea otters are polygynous, with males having multiple female partners throughout the year. Males mate with females that inhabit their territory. If no territory is established, they seek out females in estrus.

Females reach sexual maturity at 4 years of age. Males reach sexual maturity at 5 to 6 years, but may not mate until much later.
