Otter
Adapted from Wikipedia · Adventurer experience
Otters are playful animals that eat meat. They are mammals and belong to the subfamily Lutrinae. They are part of the Mustelidae family, which includes weasels, badgers, mink, and wolverines. There are 14 different species of otters. They live both on land and in water. Otters have long, slim bodies and strong webbed feet for swimming. Their thick fur helps keep them warm and float in water.
Otters love to play. They often slide into water and play with stones and other objects. They mainly eat fish, but some eat frogs, birds, or shellfish. Otters have a gestation period of about 60 to 86 days. Their young stay with their family for about a year. Otters can live up to 16 years in the wild.
Otters have had different relationships with humans over time. They were sometimes hunted for their valuable pelts. In some places, like southern Bangladesh, they have been used in fishing practices. Otters are usually not dangerous to humans and only act when they feel threatened. They have inspired many stories and beliefs. In cultures such as Norse mythology and Native American totems, otters represent different qualities. In Asian folklore, they are sometimes thought to have the ability to change shape.
Etymology
The word otter comes from an old word used by people who spoke Old English, called otor or oter. Many languages that share a common history, called Indo-European languages, have similar words. All of these words come from an even older shared word, *wódr̥, which is related to the English word "water."
Terminology
An otter's home is called a holt or couch. Male otters are called dogs or boars. Female otters are called bitches or sows. Their babies are called pups or cubs. Groups of otters can be called a bevy, family, lodge, or romp. When they are in water, they can be called a raft.
Otters leave behind droppings called spraints. These have a special smell that can help people find them.
Life cycle
The gestation period in otters lasts about 60 to 86 days. After birth, the mother and sometimes older siblings help care for the new pup. Female otters reach sexual maturity at around two years old, and males at about three years. Otters build their homes, called holts, under tree roots or rocky places, often lined with moss and grass.
After about one month, the pup can leave the holt, and after two months, it can swim. Pups stay with their family for around one year. Otters can live up to 16 years and enjoy playing in the water with their young. Their main food is fish, but they may also eat eels, frogs, and birds.
Description
Otters have long, slim bodies and short legs. They are excellent swimmers because their feet have webbing, and they can stay underwater for a long time. Most otters have sharp claws and long, strong tails, but the sea otter does not. They range in size from about 0.6 meters to 1.8 meters long.
Otters have very soft fur under a layer of long guard hairs that keeps them dry and warm in the water. Some otters, like the Eurasian otter and sea otter, eat a lot — up to 25% of their body weight each day — to stay warm, especially in cold water. Most otters spend several hours each day hunting for food.
Feeding
Otters mainly eat fish, but they also enjoy eating frogs, crayfish, and crabs. Some otters are good at opening shellfish, while others might eat small mammals or birds if that’s what’s available. Sea otters hunt clams, sea urchins, and other shelled animals. They can use stones to crack open shellfish on their bellies, a skill that young otters need to learn.
Otters are active hunters, chasing their food in the water or looking for it in river, lake, or sea beds. Most otters live near water, but river otters usually go into the water only to hunt or swim. They spend a lot of time on land to keep their fur dry. Sea otters live in the ocean most of the time.
Behaviour
Otters are playful animals that enjoy doing fun things, like making waterslides and sliding down them into the water. They also like to find and play with small stones for fun.
Otters have different social habits depending on the species. Some otters like to be alone most of the time, while others prefer to live in groups.
Species
Otters are part of the Lutrinae subfamily, which belongs to the Mustelidae family. This family also includes weasels, badgers, mink, and wolverines. There are 14 otter species alive today, and they all live near water, in both freshwater and marine environments.
In the past, many other otter species existed but are now extinct. These ancient otters lived in places like Corsica, Malta, Japan, and many parts of Europe, Asia, and Africa, from times as far back as the Late Miocene up until the Pleistocene period. One example is the Japanese otter (Lutra nippon), which lived in Japan but disappeared around 1979.

Relation with humans
Otters have been hunted for their pelts for a long time. People used otter fur to make warm clothes and accessories, like hats and belts. In some places, such as China, only very important people wore otter fur clothes.
Otters have helped people with fishing. In parts of Bangladesh, fishermen keep smooth-coated otters to help chase fish into their nets. This tradition has been passed down through families for many years.
In stories and myths from many cultures, otters play special roles. In Norse mythology, an otter named Ótr is part of an important tale. In Irish mythology, an otter accompanies a magical character. Some Native American cultures see otters as important spirit animals. These stories show how people have valued otters throughout history.
In Japanese folklore, otters are known to trick people. They are said to change shapes, sometimes appearing as beautiful people or other forms to amuse or confuse humans.
