Otter slides have a trail width of 6-10 inches (15.2 – 25.4 cm). They make overland trails to get from one water body to another.
Otter feet are webbed. Webbing is most apparent on the hind track. The smallest toe is located on the inside of the track. Front tracks show a heel pad. Rear tracks do not show a heel pad.
Otter slides are made when the otter slides on its belly and pushes forward with its feet. This creates a trough in the snow. Otters like to slide anywhere that they can.
