No, but they are endangered as they were once hunted for its pelt.

North American beavers are not endangered.
people hunt them and spill oil on them .
humans want their nice fur
well if you kill all the otters, then all the other animal they eat will have to big of a population and that is not a good thing.
Over time, the population of the sea otters has decreased and sea otters are now an endangered species. This can be blamed on human activity, as most animal species' endangerments can.
There are otters found in Scotland. It should be noted that they are not technically 'sea' otters as these are a sub species found along the coast of Japan, Canada and USA. Otters found in Scotland are Eurasian or European otters.
Well, endangered animals that typically live by rivers or lakes will probably. Hope That Helped!
