Otter - We saw two over the weekend

This otter was very curious about us. He would come forward then backwards and then pop his head out. Photos taken at 7:50pm. Very hard to take any photos and my ISO was at 2500. Crazy but amazing sighting again. the first one we saw was a long ways out on the lake and it was running and sliding across the ice. A few facts on Otters (Lontra Canadensis) Active dusk to mid morning. Can swim up to 12 km per hour. Dive 20 m and spend 4 min underwater in a single breath. Otter sliding on ice is a means of travel and playing. We saw them sliding this weekend. Diet is fish, frogs, crayfish etc.
