Description:
The North American River Otter, or Lutra canadensis, is a semi-aquatic mammal belonging to the Mustelidae family. It is recognizable by its streamlined body, webbed feet, and muscular tail. Its thick, waterproof fur ranges from dark brown to silvery gray. Measuring between 90 and 135 cm, it typically weighs 5 to 14 kg. Adapted to aquatic life, it is an agile and fast swimmer. It primarily feeds on fish, but also consumes crustaceans, amphibians, and small mammals. The river otter is a social animal, often observed in family groups. It plays a crucial role in the ecosystem by regulating fish populations and maintaining the health of waterways.

Photography tips:
To photograph the river otter, focus on twilight hours when it is most active. Use a telephoto lens of at least 400mm to capture detailed images from a distance. Be patient and discreet, as the otter is suspicious. Look for signs of its presence, such as slides on riverbanks or remnants of meals. A tripod can be helpful to stabilize your camera in low-light conditions.
