I had a manatee that was just lying in shallow water, other than breathing now and then, it wasn't really moving at all. I also noticed white around the snout, which indicates cold stress. I called Fish and Wildlife, and after laying there for over 2 hours, the stupid manatee just up and swam off literally 1 minute before FFW got there. But here are some pictures, I really did see a sick manatee, we just couldn't do anything about it cause it took off. Hopefully it will warm up or at least find a warmer place to hang out.
