What is a Smooth-Coated Otter?

About 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

Q1) What are peat swamp forests?

Peat swamp forests form in areas where saturated soils or frequent flooding prevent organic material from fully decomposing. As this organic material slowly accumulates, it retains even more water through capillary action: up to 13 times its weight. Acting as a giant sponge that holds in the moisture, peat swamps eventually form a dome of wet organic material that can rise above the surrounding flood levels.
