What happens to otters in winter when the lake is frozen, I wondered. Does the family stay together or disperse? Do otters have any special survival strategies to get through the cold times?

At the end of last summer, as I sat in an eddy on the Clark Fork River, something furry and black caught my eye, moving as smoothly as the water itself. I was looking at a North American river otter. Remembering studying sea otters in elementary school, I wondered if I had just seen something rare for this region, and decided to do a little research.
