I was totally caught by surprise to see three River Otters pop up out in front of where I was alongside the pond. It was like a bow wave of a submarine coming across the pond when suddenly three heads popped up. I watched this group for over 30 minutes while they played and caught fish. In that 30-minute period I think they must have caught 20 or so fish (carp). I captured what action I could before they disappeared just as quickly as they appeared.
