Asian Small-Clawed Otter
Aonyx cinereus · also called oriental small-clawed otter
Feeling through mud and crevices with unusually dexterous paws rather than hunting by sight, the Asian small-clawed otter holds the title of the world’s smallest otter species, living in close-knit family groups across the wetlands of South and Southeast Asia.
Overview
The Asian small-clawed otter, Aonyx cinereus, is the smallest otter species, native to wetland and coastal habitat across South and Southeast Asia. Its exceptionally dexterous, only partly webbed paws, tight-knit multigenerational family groups, and touch-based hunting technique make it one of the most behaviourally distinctive otter species found anywhere in the world.
Hands built for feeling, not just swimming
While most otters rely heavily on sight and speed to catch prey, the Asian small-clawed otter has developed some of the most sensitive, dexterous paws in the otter family, letting it hunt effectively even in murky water where vision offers little advantage.
Status
Vulnerable, with populations declining across South and Southeast Asia due to habitat loss, pollution, and the illegal pet trade.
Asian Small-Clawed Otter: common questions
Is the Asian small-clawed otter really the smallest otter species?
Yes, this species is the smallest otter species alive, noticeably more compact than its river-dwelling and marine relatives found elsewhere in the world.
How does the Asian small-clawed otter find food?
This species locates hidden prey such as crabs and shellfish mainly by touch, using its unusually dexterous, only partly webbed paws to probe mud and crevices rather than relying on sight.
Does the Asian small-clawed otter live alone?
No, this species lives in close-knit family groups, often extending across multiple generations, that cooperate in foraging, grooming, and raising young together.
Why is the Asian small-clawed otter considered Vulnerable?
This species has declined across South and Southeast Asia due to habitat loss, water pollution, and capture for the illegal pet trade, leaving it classified as Vulnerable despite its wide historical range.
