There are many types of river otters, and some are social while others are not. The Giant River Otter from the Amazon lives in packs, as do North American river otters, female Southern river otters, (males are solitary). The European river otter is extremely territorial.
There are sea otters and other otters. In the category of "other" otters, you can include the North American River Otter, Giant Otter of South America, Asian small clawed otters, Congo clawless otters, Capr clawless otters, Southern river otters, hairy nosed otters, spot necked otters, neo tropical long tailed otters, and others I may fail to mention.

There are many types of river otters. The only way I could answer your question would be if you said which type you were referring to. If you mean the giant river otter, it is threatened by habitat loss and poaching, and fishermen sometimes kill them because they think that the giant river otters are a nuisance. In the past, otter pelts were very valuable, and massive amounts of hunting have decimated populations of many, if not all, species of river otters worldwide.

In 2007 the population was recorded as 3,026, then in 2008 it was listed as 2,760. The current listing for 2009 is 2,654, another decline. They are protected but many factors are related to their current population status, and they are being studied to determine what action may help stop the decline.
