Otters have little pouches under each forearm to store food gathered after long hunting hours. They also use the pouch to store stones as hunting tools.

North American otters are semi-aquatic mammals belonging to the family Mustelidae and are found across the continent in freshwater rivers, lakes, and coastal marine environments.

There are two species of otters native to North America: the river otter (Lontra canadensis) and the sea otter (Enhydra lutris).

River otters have long, streamlined bodies, webbed feet, and thick, waterproof fur that keeps them warm in cold water.

They are highly social animals, often living in family groups called rafts, which consist of a breeding pair and their offspring from previous years.

River otters are agile swimmers and excellent divers, capable of holding their breath underwater for several minutes while hunting for fish, amphibians, crustaceans, and other aquatic prey.

They have acute senses of sight, hearing, and smell, which help them locate prey and navigate their aquatic environment.

River otters are playful animals, often engaging in social behaviors such as sliding down riverbanks, chasing each other, and wrestling.

They communicate using a variety of vocalizations, including chirps, whistles, and growls, as well as body language and scent marking.

River otters build dens in riverbanks, marshes, and other secluded areas, using vegetation, mud, and rocks to construct their nests.

They play important ecological roles in freshwater ecosystems by controlling populations of prey species and influencing habitat structure.

River otters are vulnerable to habitat loss, pollution, and human disturbances, although conservation efforts have helped some populations recover in recent years.

They have cultural significance in indigenous cultures and folklore, often symbolizing traits such as playfulness, adaptability, and resilience.
