7 Unique Facts About Otter

Some otter species, such as sea otters, are known for their incredible tool use. They use rocks and other objects to crack shellfish and crustaceans, demonstrating a level of intelligence and adaptability in their feeding habits.

Otters have very dense fur, up to one million pelts per square inch. This dense fur provides excellent insulation, keeping them warm in cold water. To maintain their insulating properties, otters must keep their fur clean and free from oil, so they spend a lot of time grooming.

Otters are often quite social animals. River otters, for example, are known to live in family groups and engage in playful behaviors. They glide on muddy banks, wrestle with each other and even play tag, which helps build social bonds and practice important skills.

Otters communicate with a range of vocalizations, including chirps, whistles, and growls. These sounds help them communicate with family members, establish territory, and alert each other to potential danger.

Otters have a unique feature called a "pouch of loose skin" located around their necks. This pouch allows them to store and carry food, small stones, and other items they collect while foraging. It's a handy way for them to transport valuable resources.

Otters have highly sensitive whiskers, also known as vibrissae, which they use to detect movement and changes in their surroundings underwater. These whiskers help them navigate, locate prey, and avoid predators.

Otters are known for their playful nature, both in water and on land. This play isn't just for fun—it serves practical purposes, such as teaching young otters essential survival skills. Playful activities like sliding down slopes and practicing hunting techniques contribute to their development and adaptation.
