The River Wolf

Unfortunately these animals are still listed as an endangered species. This is mainly because of an expected increase in problems like habitat loss. There has also been a history of conflict between these otters and local fishermen, who think that the otters deplete the river’s fish. Gold mining in this area also leads to habitat loss and mercury poisoning (mercury is used to mine the gold, and gets into the river water).
There are options for ecotourism in their habitat now but it is still debated as being potentially helpful or hurtful to the otter’s survival. It brings the issue to light for many people, but can create unnecessary stress for the otters. These grumpy fishermen are yet another species that seems indestructible until it meets humans. Hopefully conservation efforts in the area are able to preserve the otter’s habitat and ensure its survival.
