The National Red List Project

Please note, this National Red List website contains a subset of data whilst we transition to national focal point driven data uploads. We thank you for your patience with this and welcome national contributors to get in touch to update their national dataset. Terms of Use including citation guidance are found here.

The previous dataset is available via: https://archive.nationalredlist.org/. This site is no longer updated but can help with most enquiries whilst we focus on redevelopment.

Habitat
Habitat details as listed in assessment
It occurs in a wide variety of aquatic habitats including rivers, streams, lakes, swamps, marshes, rice-fields, swamp forests and coastal wetlands. It is active at night and spends the day roosting in a burrow or a hollow of tree. It catches the prey by mouth several times a day. Feeds mainly on fish and crustaceans, but also on small mammals, birds, bird eggs, insects, worms and even vegetation. Consumes about one kilogram of food daily. Mates in water or on land and breeds year-round. Female lays 1-4 cubs after a gestation period of about 63 days. Female mainly takes care of young for one year until the young becomes sub-adult (Grzimek 1990, Asmat 2009).

Assessment rationale/justification
The species is known to occur in wetland habitats of Greater Sylhet and Greater Mymensingh (IUCN Bangladesh 2003, Asmat 2009) but there is no recent sighting. Once it was widespread in Bangladesh (Asmat 2009, Khan 2015) but its population has been reduced rapidly, which is still going on. Many of its former habitats have been dried out or converted, causing the decline of its Extent of Occurrence. Thus, the species is listed as Critically Endangered.
