Looking at this photo of a manatee nose, you will understand why so many have prop wounds. This is all most boaters can ever see of the one-ton-plus marine mammals, as they raise only their nostrils out of the water to breathe. The manatee in my previous manatee posting ( http://sudoku.com.au/PhotosBig.aspx?PID=7876&UID=9623&Go=R28-5-1991 ) had prop scars on it. 419 Manatees died in Florida this year, a new high. Please obey "Manatee-Slow" signs. Like deer, you DON'T want to hit one!
