Smooth-coated otter

This otter has very short fur.

Its fur is dark brown. Its belly is a lighter color.

It has a round head. It also has a flat tail. This helps it swim in rivers. Its feet have skin between the toes. This helps it move through the water. It uses sharp claws to catch slippery fish. These otters live in groups. They can have up to eleven friends. They like to eat fish and rats. They can even live in cities.

These otters are very special animals.

The smooth-coated otter lives in parts of Asia.

Most of them live in Southeast Asia. They like places with plenty of fresh water. This includes rivers, lakes, and even rice paddies.

These otters have short, sleek fur. Their backs are dark brown or reddish-brown. Their undersides are a lighter gray-brown. They have a round head and a flat tail.

Their strong legs have webbed feet. They also have sharp claws to catch slippery fish.

Smooth-coated otters live in groups of up to 11. They eat mostly fish. Sometimes they hunt rats in rice fields. They also eat snakes and insects. When they hunt fish, they may swim in a V-shape. This makes the fish jump out of the water. Then the otters catch them with their snouts.

In Singapore, these otters live in cities. They can use gaps under buildings for homes.

Sadly, they are a vulnerable species. This means they are at risk. They face threats from pollution and losing their homes. People also hunt them illegally.

The smooth-coated otter is a special kind of freshwater otter.

These animals live in many parts of South and Southwest Asia. Most of them can be found in Southeast Asia. They need plenty of fresh water to live well. This includes places like rivers, lakes, and seasonal swamps. They also like rice paddies and wetlands. Because they face many dangers, they are called a vulnerable species. This means they are at risk of disappearing.

These otters have a very specific way they look. Their fur is short and sleek, which is why they have their name. The fur on their backs is dark-brown or reddish-brown. Their undersides are a lighter grayish brown. They have a head that looks rounded. Their nose is hairless and shaped like a diamond.

Their tails are flat instead of being round. To catch slippery fish, they use strong legs and webbed feet. They also have sharp claws to help them grab prey.

People have studied these otters for a long time. In 1826, Isidore Geoffroy Saint-Hilaire gave them their scientific name. He used a brown otter from Sumatra for this. Later, in 1865, John Edward Gray proposed the name Lutrogale. This name was for otters with a more curved forehead. In 1940, Reginald Innes Pocock described a subspecies in Pakistan. In 1957, Robert William Hayman named another subspecies after Gavin Maxwell. This one was found near the Tigris River in Iraq.

Smooth-coated otters are very clever hunters. They often live in groups of up to 11 individuals. When they hunt fish, they can work together in a line. This line looks like the letter V. The otters swim in this shape to scare the fish. The fish jump out of the water in panic. Then, the otters dive down and catch them with their snouts. They move to the muddy bank and swallow the fish head-first. They eat fish like catfish and gourami. They also eat rats, snakes, and insects.

Some otters have learned to live near people in cities. In Singapore, they use urban structures for their homes. They might live in gaps under buildings. They even use stairs and ladders to get in and out of concrete canals.

In southern Bangladesh, people even work with these otters. Fishermen train them to chase fish into nets. However, these otters still face hard jobs. Pollution and losing their habitats make life difficult. People also hunt them for the illegal pet trade. We must protect them so they can thrive.

The smooth-coated otter, known scientifically as Lutrogale perspicillata, is a specialized freshwater mammal.

It is found across much of South and Southeast Asia. This species is currently classified as vulnerable on the IUCN Red List. This means it faces a high risk of extinction in the wild. The species suffers from habitat loss, pollution, and illegal poaching. Most smooth-coated otters live in the tropical regions of Southeast Asia. They rely on healthy wetland ecosystems to survive and thrive.

Physically, these otters are built for an efficient life in the water. Their name comes from their short, sleek fur. The coat is dark-brown or reddish-brown on the back. The underside is a lighter grayish brown. They have a distinct, rounded head shape. Their nose is hairless and shaped like a diamond. Unlike many other otters with cylindrical tails, these have flattened tails. Their short, strong legs end in large, webbed feet. These feet feature sharp claws for gripping slippery prey.

The taxonomy of this species has been shaped by many scientists. In 1826, Isidore Geoffroy Saint-Hilaire proposed the name Lutrogale perspicillata. He based this on a brown specimen from Sumatra. Later, in 1865, John Edward Gray proposed the genus name Lutrogale. He chose this for otters with a more convex forehead. Different subspecies have been identified in various regions. For example, Reginald Innes Pocock described a subspecies in Pakistan in 1940. Robert William Hayman named another subspecies in 1957 after the naturalist Gavin Maxwell.

Smooth-coated otters are social animals that live in groups. These groups can include up to 11 individuals. They often live in family units with a mated pair. A group might also include up to four offspring from previous seasons. They establish dens, or holts, under tree roots or among large boulders. In some urban areas, they have adapted to man-made structures. In Singapore, they use gaps under buildings as homes. They have even been seen using stairs and ladders to climb concrete canal banks.

These otters are highly effective group hunters. They often forage for food along river banks. Their diet consists mainly of fish, such as catfish and climbing gourami. During rice planting seasons, they may also hunt rats. When hunting in creeks, they use a clever V-shaped formation. The otters swim in an undulating line to scare fish. This movement causes fish to jump out of the water in panic. The otters then dive to catch the fish with their snouts. They swallow the fish head-first on the muddy banks.

Reproduction in this species is closely tied to the environment. They can breed throughout the year if food is plentiful. However, in areas dependent on monsoon rains, they breed between October and February. The gestation period, or the time a mother carries young, is 60 to 63 days. A typical litter contains up to five pups. In Singapore, a wild-born litter of seven pups was recorded in 2017. Pups are born blind and helpless. They open their eyes after 10 days and are weaned by five months.

Human interaction with these otters varies greatly. In southern Bangladesh, fishermen use them for commercial fishing. They train the otters to chase fish into nets. By 2011, about 300 fishermen used this method. However, other human activities are dangerous. Pollution from pesticides like organophosphates harms their water. Habitat destruction for agriculture and hydroelectric projects reduces their space. They are also targets for the illegal pet trade. In 2013, six juveniles were found in a bag at an airport.

Conservation efforts are vital for the survival of the smooth-coated otter. The species is protected in most of its home countries. It has been listed under CITES Appendix II since 1977. In August 2019, it moved to CITES Appendix I. This change provides even stronger international protection against illegal trade. Protecting wetlands is the most important way to help them. Keeping water clean and preserving rivers ensures they have enough food.
