This photo was taken by Capt. Dave Leahy, "KEYSMON". You can clearly see the propeller wounds and Luigi's lung protruding from one of the wounds. For more information on Florida Manatees go to this link:

Luigi taking a break and maybe even saying "help me"
Boater's that disregard the idle speed rules are responsible for damage like this to Manatees! Report violators!
