Inspired by the Gliawards current otter-theme I wanted to make a post about Giant River Otters (オオカワウソ).
These otters are different from both the otters found in Europe and the ones in the Arctic. To begin with they are huge (up to 1,7 meters). They are also much more social than other species. They like to hang out in family groups of 3-8 individuals and also hunt in packs! 
For more info about this endangered species, see Otterly Fascinating | Science | Smithsonian Magazine
The whole family out for a swim!
