Smooth-Coated Otter (Lutrogale perspicillata)

The Smooth-Coated Otter resides in the waterways of South and Southeast Asia. It can grow up to 3.5 feet long, including its tail. Moreover, it sports smooth and short, glossy brown coats that inspired its name. Its upper parts are dark but lighter brown on its underside.

Interestingly,  Smooth-Coated Otters can quickly adapt to human-altered landscapes such as rice fields and canals. Some otter populations are even surviving and being protected by authorities in Singapore.

Their hunting tactics involve groups forming a semi-circle in the water to drive fish toward the shore, making them easier to catch. Besides hunting, they also engage in friendly activities such as sliding down muddy banks, wrestling, and chasing their tails.
