Eurasian otter raises hope for J&K stream
Subject : Environment
Section: Species in news
Context: The first photographic record of the semi-aquatic carnivorous mammal has indicated that some stretches of the Neeru stream, a tributary of the Chenab River, are still unpolluted.
More on the News:
- A trio of scientists from the University of Jammu’s Institute of Mountain Environment (IME) at Bhaderwah camera-trapped three Eurasian otters – two adults and one sub-adult – in the Neeru stream of the Chenab catchment.
- Apart from putting an end to doubts about the animal’s presence in the upper Chenab catchment, their findings have confirmed that some stretches of the Neeru remain unpolluted. The Neeru is a tributary of the Chenab river.
Eurasian otter:
- Eurasian otter (Lutralutra) is a semi-aquatic mammal found in Europe, Asia, and parts of North Africa. Mammals of the family Mustelidae with seven genera and 13 species
- Habitat: Eurasian otters are found in freshwater habitats such as rivers, streams, and lakes, although they may also occur in coastal areas.
- They are generally found in areas with abundant fish populations.
- The Eurasian otter covers the largest range of any Palearctic mammal, covering parts of three continents – Europe, Asia, and Africa.
- Diet: Eurasian otters are carnivorous and feed primarily on fish, although they may also consume other aquatic prey such as crabs, frogs, and insects. They are active mainly at night and are generally solitary, although family groups may sometimes be observed.
- Adaptations: Eurasian otters have webbed feet and a sleek, streamlined body that is well adapted for swimming and diving. Their fur is thick and waterproof, providing insulation and protection from the cold water.
- Conservation status: The Eurasian otter is listed as “Near Threatened” by the IUCN Red List.
- Threats: habitat loss and degradation, pollution, and hunting.
- Ecological role: Eurasian otters play an important ecological role as top predators in freshwater ecosystems. They help regulate fish populations and maintain the health of aquatic habitats.
