Otter Enjoying a Crayfish Snack

I had been trying to capture these guys for over a year, but I was always late to the party. I remember a fellow photographer mentioning to look out for swirls in the water. I walked along the boardwalk, spotted the swirls, and then watched them devour dozens of crayfish over the next hour. This picture was shot at ISO 100,000; it would have been impossible just a few years ago!
