Reproduction in the Hairy-Nosed Otter

Wright et al (2008) consider that this species has the normal otter gestation of 2 months (63 days) and that the breeding season is from November to February, possibly varying a little according to location and prey availability.

The male may possibly stay with the female and contribute to raising the cub(s) as small groups containing more than one adult have been seen.
