Smooth Coated Otter
The smooth-coated otter (Lutrogale perspicillata) is an otter species occurring in most of the Indian subcontinent and Southeast Asia, with a disjunct population in Iraq.
As its name indicates, the fur of this species is smoother and shorter than that of other otter species.
The smooth-coated otter is a relatively large otter, from 7 to 11 kg (15 to 24 lb) in weight and 59 to 64 cm (23 to 25 in) in head-body length, with a tail 37 to 43 cm (15 to 17 in) long.
It is distinguished from other otter species by its more rounded head and a hairless nose in the shape of a distorted diamond. Its tail is flattened, in contrast to the more rounded tails of other otters. Its legs are short and strong, with large webbed feet bearing strong claws. As its name suggests, it has unusually short and sleek fur; this is dark to reddish brown along the back, while the underside is light brown to almost grey in color. Females have two pairs of teats.
The smooth-coated otter has been recorded in Pakistan, India, Nepal, Bhutan, Bangladesh, southwest China, Myanmar, Thailand, Vietnam, Malaysia, Singapore, Indonesian islands of Borneo, Sumatra and Java, and Brunei. An isolated population is also found in the marshes of Iraq.
It occurs in areas where fresh water is plentiful — wetlands and seasonal swamps, rivers, lakes, and rice paddies. Where it is the only occurring otter species, it lives in almost any suitable habitat. But where it is sympatric with other otter species, it avoids smaller streams and canals in favour of larger water bodies.
Although it is often found in saltwater near the coast, especially on smaller islands, it requires a nearby source of fresh water.
Smooth-coated otters are social and hunt in groups. They are mainly diurnal, and have a short lull in activity during midday.
They spend the night in dens dug in dense vegetation, under tree roots, or among boulders. They use scent to communicate both within the otter species, and with other animals.
Each otter possesses a pair of scent glands at the base of the tail which are used to mark land or objects, such as rocks or vegetation, near feeding areas in a behavior called sprainting. They also communicate through vocalisations such as whistles, chirps, and wails.
Some may construct permanent holts near water, in a layout similar to that of a beaver dam, with an underwater entrance and a tunnel that leads to a nest above the water.[citation needed]
Fish comprise over 70% of their diet, but they also eat reptiles, frogs, insects, crustaceans, and small mammals. Especially in areas where other species of otter are also found, they prefer larger fish, typically between 5 and 30 cm (2.0 and 11.8 in) in length. They sometimes hunt in groups of up to 11 individuals.
