River otters are opportunistic feeders, meaning they will take advantage of any available food source. This means that a 20-pound otter may eat around 3-4 pounds of food daily. On average, an adult otter can consume around 15-20% of its body weight in food each day. The amount of food a river otter consumes depends on various factors, including the availability of prey and the otter’s size and activity level. Otters are also known to consume amphibians, such as frogs and salamanders, as well as crustaceans like crayfish and crabs. They are skilled hunters and can catch fish using their sharp teeth and strong jaws. River otters have a varied diet that primarily consists of fish. The Diet of River Otters: What and How Much Do They Eat? To protect themselves, otters rely on their keen senses, including sharp hearing and a strong sense of smell, to detect potential threats. These predators may target otters when they are on land or during their travels between water bodies. River otters also face predation from terrestrial predators such as coyotes, bobcats, and large birds of prey. Otter survival tactics include staying close to cover and utilizing their agility and speed to evade capture. These aquatic predators pose a threat to otters, especially when they are young and vulnerable. In freshwater habitats, river otters may encounter predators such as alligators, crocodiles, and large predatory fish like pike or muskellunge. However, they are not at the top of the food chain and face threats from other predators. As carnivorous mammals, they have a diverse diet consisting of fish, amphibians, crustaceans, and even small mammals. River otters are primarily predators rather than prey. This behavior allows them to take advantage of the low light conditions when hunting for prey. They are crepuscular animals, meaning they are most active during twilight. In terms of activity, river otters are most active during the early morning and late evening hours. By the age of six months, they are proficient swimmers and can catch their own food. This is an exciting time for the young otters as they begin to explore their surroundings and develop their hunting skills. Once the pups are around two months old, they start venturing out of the den and learning to swim. These adorable pups are born blind and helpless, relying on their mother for nourishment and protection. The gestation period lasts around two months, and female otters give birth to litters of one to six pups. River otters typically breed in late winter or early spring, with the young being born in the following months.
