Description of Otters

Otters are adorable creatures in many parts of the world and always make a lot of noise when they appear. Playful, curious, and affectionate animals, otters are sure to put a smile on your face.

These playful creatures are often associated with luck and fortune, making them popular for tattoos and merchandising. But what most people don't realize is that otters are also among the most efficient predators in the animal kingdom. They can hunt prey much larger than themselves, they are skilled hunters.

This article covers everything you need to know about the world of otters. From their physical characteristics to their behavior in the wild, we'll explore everything there is to love about these mischievous creatures. So sit back and have fun while learning about one of nature's most beloved animals!

Otters have relatively short limbs and long, slender bodies. Its most distinctive anatomical features are its powerful webbed feet, which it uses to swim, and its seal-like ability to close its nostrils and ears underwater. Specifically, otters have a unique reproductive system called delayed implantation. This means that although a litter of otters is born in the spring, their mothers delay embryo implantation until the following winter.

Otters are small to medium-sized mammals with compact bodies, short legs, and long, thin tails. They have a thick, waterproof coat that keeps them warm in the water. The fur is usually brown or black, but can also be gray, silver, or white. Otter's noses are unique among mammals in that they can close underwater they have small eyes and ears.

Otters come in different sizes in different parts of the world. The sea otter is the largest species of otter. It can grow up to 4 feet in length and weigh up to 99 pounds. The river otter is smaller. It is about 2.5 meters long and weighs up to 22 kilograms.

Classification of Otters

Otters are carnivorous mammals of the subfamily Lutrinae. Lutrinae is a branch of the weasel family Mustelidae, which also includes badgers, minks, minks, and wolverines, among others. The 13 extant otter species are all semi-aquatic, aquatic, or marine, with a diet based on fish and invertebrates. These species range from the Asian small-clawed otter to the giant otter.

Species of Otters

Freshwater otter


Often referred to as river otters, the 11 species are found in North America, South America, Europe, Africa, and Asia in freshwater ecosystems that support a wide variety of prey including fish, crustaceans, crabs, clams, and frogs. Most river otters are opportunistic and will feed on what is best available.

Diet often varies seasonally or locally depending on available prey. River otters hunt visually while chasing fish, but use their manual dexterity to scare crabs and lobsters under rocks. Sensory hairs on the snout called vibrissae also help detect turbulence in the water. After being caught with the teeth or front legs, the prey is eaten in the water or on land.

Saltwater otter

Two otter species are exclusively marine: the sea otter (Enhydra lutris) of the Pacific coast of North America and the much smaller sea otter (Lontra Felina) of the coasts of Peru and Chile. Both rely solely on marine prey, although sea otters can be found much further offshore; The sea otter is about 100 meters (330 feet) from shore

Sea otters are well adapted to sea life.

The front and hind paws are fully webbed; large lungs allow long dives and provide buoyancy, and the thick fur provides insulation. In addition, sea otters can drink salt water and can therefore stay in the sea for several days at a time. Sea otters are usually solitary but are sometimes seen in groups; Gatherings of up to 2,000 people have been observed along the Alaskan coast.

Habitat of Otters

The only continents without otters are Australia and Antarctica, and the only habitats they don't live in our deserts, polar regions, and mountains. The most common otter is the Eurasian otter, found in Europe, North Africa, and Asia as far north as Japan and Indonesia. The otter's typical habitat includes water and land, with the exception of the sea otter, which rarely lands.

With the exception of sea otters, otters live in burrows that are mostly dug out by other wildlife such as beavers. They can also live on rocks or logs. The beaver habitat is a great place to find otters as otters take advantage of the dams and burrows that beavers build. A typical river otter territory includes a multi-passage burrow with a dry inner chamber, grass or sand-covered areas for rolling and cleaning, sliding down muddy or snowy embankments, and feeding areas.

Diet of Otters

Otters are carnivores and the river otter's diet consists primarily of fish, crab, shrimp, crustaceans, and mollusks. They are skilled hunters, using their sharp claws and teeth to capture their prey. In addition, river otters will eat frogs, snakes, birds, and small mammals when given the opportunity. Sea otters eat sea urchins, squid, fish, crabs, abalone, clams, and mussels.

River otters are voracious eaters that need to eat frequently to keep up with their energy metabolism. Sea otters require about a third of their body weight in food on a daily basis.

Reproduction of Otters

Otters reach sexual maturity at 2-3 years. Mating usually takes place in the water, with females giving birth to litters of 1–5 pups after a gestation period of 60–90 days. Newborn otters are blind and helpless, relying on their mother for warmth and protection. Otters are often called cubs or kittens.

Otters are weaned between 4 and 12 weeks and begin learning to swim and hunt around the same time. Young otters stay with their mother for 6-18 months before dispersing in search of their territories. River otters do not breed until they are 5 years old.

Behavior of Otters

Otters are found in rivers, lakes, and marine environments around the world, but are particularly common in the Northern Hemisphere. Otters live in different bodies of water. Otters that live in the ocean are called sea otters, and otters that live in freshwater are called river otters.

Most otters live in small family groups consisting of a mother and her offspring, but some species are solitary. Otters are very playful animals and their social play often resembles a fight. The otter's primary mode of locomotion on land is by crawling, but it can also move quickly by galloping or hopping. In the water, otters swim with their powerful tails and webbed feet.

Intelligent and curious animals, otters are known to use tools. For example, some otters in Scotland have been observed using stones to open crab shells.

Although otters are generally elusive and shy, they can be surprisingly aggressive when defending their territory or they're young. Male otters are particularly territorial and fights between them are not uncommon.

Otters are very vocal animals that produce a variety of sounds including hissing, growling, growling, and screeching. The purpose of these vocalizations is largely unknown, but they can be used to communicate alarm, aggression, or desire.

State of preservation of Otters

Humans hunt otters for their meat, fur, and organs. They are also sometimes kept as pets. In some parts of the world, they have often been killed by fishermen, they are considered otters a nuisance because they feed on fish populations. 

However, their populations are declining in some areas due to habitat loss and pollution. The southern sea otter is an endangered animal that almost went extinct in the early 20th century but is being rebuilt thanks to an international agreement.

California sea otters, also known as southern sea otters, have been slow to recover as there has also been pollution in their waters and an increase in commercial fishing operations that could have caused devastation.

Of the 13 otter species, the IUCN has listed five species as vulnerable, including the giant otter, South American river otter, sea otter, sea otter, and hairy-nosed otter. The single species of Least Concern is the otter in the North American river.

Threats of Otters

Because of their luxurious and dense fur, some otter species have been hunted to extinction for their fur. Poaching, pesticide use, and habitat loss also threaten otter populations around the world, and in areas like the Amazon Basin, toxic pollutants from mines are affecting water prices, and natural bodies of water where otters live and hunt.

Long-term conservation has been granted to some otter species, particularly sea otters, and some populations are gradually increasing from dangerously low numbers.

In Bangladesh, fishermen still breed and use smooth-haired otters to cast fish in their nets, although with the introduction of technology that makes fishing more efficient, the practice has fallen away.

Lifespan of Otters

Otters are relatively long-lived animals, with some species living up to 20 years in the wild. However, their life expectancy in captivity is generally much shorter.
