American River Otter - Lutra canadensis
North American river otter is one of the most popular and endearing
of the continent's mammals. This popularity stems from their
perceived playfulness and seemingly boundless energy.

Otters have extremely high metabolisms which require that
they spend large portions
of each day eating
it may also account for the fact that they never store
food but consume their prey immediately upon capture.
Otters like many mustelids (the family of mammals that includes weasels, badgers,
wolverines etc.) have a reproductive adaptation called delayed implantation.
This means that immediately after fertilization, the embryo goes into stasis,
and only resumes when conditions are favourable for implantation and eventual
birth. While Otter gestation is 63-65 days actual birth usually occurs 10-12
months after mating.
