Asian small-clawed otters are the most social among the otter species. They are often seen living in groups of 12-20 individuals. These diurnal animals are often seen playing, sliding down on mud banks and juggling pebbles and small objects.
Although small-clawed otters spend most of its time on land, these animals are excellent swimmers. When swimming, they use their back legs and tail. They also close their ears and nostrils when they’re underwater.
These otters are very clever that they are seen leaving their hunted crab out in the sun so that their shells will crack open. Indian fishermen have also trained otters to help them catch fish.
