In Alaska, Canada and the northern United States the North American river otter (Lontra canadensis) suffered over-hunting. More than 33,000 pelts were sold in 1983/4 hunting season (for $18.71 each), but it is now protected internationally and trade is controlled.
This otter is a similar size to the Eurasian otter, growing up to 90cm long with a 45cm tail, and has the same dark brown dense fur with paler undersides. Its den or holt is built into the river bank, often with an underwater entrance. Here the litter of 1-5 cubs is born and, although the mother chases the male away soon after giving birth, he is later allowed back to help care for them.
With its webbed feet and agility in the water, the otter is an excellent fisherman. Otters have been tamed and trained to hunt fish for their handlers.
