Small-Clawed Otters of the Sundarbans: Nature’s Playful Hunters

The Sundarbans, a sanctuary of rich biodiversity, is home to the fascinating small-clawed otter (Aonyx cinereus), locally known as Udbiral or Dhaira Ud. Resembling a mongoose with their sleek, agile bodies, these otters are more commonly spotted along the banks of canals and shaded waterways of the Sundarbans. Known for their black-and-white skin coloration, these charismatic creatures are a vital part of the mangrove ecosystem, playing an essential role in maintaining ecological balance.

Small-clawed otters prefer shallow freshwater streams, rivers, coastal areas, and forested wetlands. Their habitat in the Sundarbans provides the perfect environment, with abundant food sources and shaded retreats. Unlike other otter species, these otters use their dexterous forepaws to forage for food, such as small fish, crabs, shellfish, and other soft-bodied aquatic animals. Their extraordinary vision, equally sharp both above and below water, aids them in their hunting endeavors. Remarkably, they emit distinctive vocalizations while eating, a behavior unique to their kind, adding a touch of charm to their already engaging nature.

These otters are typically solitary or found in pairs, though small family groups are occasionally observed. Known for their lifelong pair bonds, they exemplify strong familial ties. The small-clawed otter is an apex predator in its niche, contributing to the health of the aquatic ecosystem by controlling the population of smaller aquatic creatures.

While the Sundarbans provide a safe haven, small-clawed otters face threats from habitat loss, pollution, and human encroachment. As these playful hunters continue to enchant visitors and enrich the biodiversity of the region, concerted efforts to conserve their habitat and mitigate threats are critical for their survival.

Through a combination of ecological awareness and sustainable conservation practices, the small-clawed otters of the Sundarbans can continue to thrive, remaining an integral and delightful part of this UNESCO World Heritage Site.
