SMOOTH COATED OTTER - ENVIRONMENT

News: Insufficient data hinders otter conservation in northeast India

 

What's in the news?

       With some of the best otter habitats in India, the northeast region is home to all three otter species found in the country.

 

Key takeaways:

       A low-profile species, otters are under-researched across India. The first otter survey in northeast India was conducted along the Kameng river in Pakke Tiger Reserve only in 2019.

       Otters in the region are threatened by excessive hunting for the illegal wildlife trade and unsustainable fishing.

       Experts say detailed surveys and research inputs on the species are needed to formulate effective conservation plans.

 

Smooth-Coated Otter:

       It is a species of otter, the only extant representative of the genus Lutrogale.

 

Scientific Name: Lutrogale perspicillata

 

Distribution:

       They are found throughout much of southern Asia, from India eastward.

       There is also an isolated population found in the marshes of Iraq.

 

Habitat:

       They are mostly found in lowlands, coastal mangrove forests, peat swamp forests, freshwater wetlands, large forested rivers, lakes and rice paddies.

       Some build permanent burrows near water with an underwater entrance and a tunnel that leads to a chamber above the high-water line.

       Although adapted for water, smooth-coated otters are equally comfortable on land and can travel long distances overland in search of suitable habitat.

 

Features:

       They are the largest otter in Southeast Asia. They weigh 7-11 kg as adults and can be up to 1.3 m long.

       As its name indicates, the fur of this species is smoother and shorter than that of other otters.

       The fur is light to dark brown dorsally and light brown to almost gray ventrally.

       They have short, tightly packed under fur and longer, water-repellant guard hairs.

       They are strong swimmers and hunt in groups. When fishing, they travel in a V-formation going upstream.

 

Conservation Status:

       IUCN Red List: Vulnerable

       Wildlife Protection Act, 1972: Schedule II
