My wife and I were walking the beach in Maine (saltwater) and I spot this dead fish in the surf. After a closer look, I determine it's a LMB. My wife was joking that my LMB in the pond missed me as I had been on vacation for 2 weeks. My guess is that the heavy rains we had last month caused this one to spill over the dam eventually making it to the ocean where it died and floated up on the beach.
In the years since purchasing the Maine house, we've seen many strange things float up on the beach, but this is a first.
