19x Postcard of River Otter (Lutra Canadensis) Marine Life The river otter is a playful animal that seems to enjoy sliding down snow and frolicking in the water with other otters. It is at home on land or in the water. Its thick and beautiful coat was once in high demand, and fur trappers depleted their numbers significantly. More recently air and water pollution has harmed many otters. Photographer- Kim Hart Postcard size 4 x 6
