The piscivorous habits of giant otters lead to negative human perception and conflicts with fisheries. I have sequenced, assembled and annotated the de novo sea otter genome, and compared it to the giant otter genome to discover genetic changes associated with aquatic adaptation and the impact of the extreme fur trade bottleneck on genetic diversity. Giant otter populations were decimated throughout their range by the fur trade, for example, 1000–3000 pelts were exported annually from the Brazilian Amazon during the I hope you like reading on Otter vs Beaver vs Muskrat fight comparison. The neotropical otter, southern river otter, and giant otter are all native to South America and are threatened by pollution and habitat destruction.

The giant otter (Pteronura brasiliensis) is an endangered semi-aquatic carnivore of South America. In 2012 a giant otter escaped from its enclosure in Hamburg zoo and attacked a cleaning lady. Giant otter spatial distribution has been related to prey abundance and local habitat conditions (Carter and Rosas, 1997, Davenport, 2010, Rosas-Ribeiro et al., 2012) that are thought to determine core group territory (Carter and Rosas, 1997).
