Caught this just at the right moment! They were having a little play and caught one otter just about kicking the other one in the face!
This is an oriental small-clawed otter (Aonyx cinerea), also known as the Asian small-clawed otter.
They are mostly social animals. They live in extended family groups of about 12 individuals. They are often seen playing and sliding on muddy banks and in the water in regions where they frequently visit or live.
