Everyone asks us how we know one manatee from another... from their scars. I wish I could say these photos are from an unfortunate few but the opposite is true..it is a rarity to see one without prop injuries/scars. Nonpropped water vehicles are better but still not the answer. The manatees lungs are on their backs, either side of the spine, and impact causes their lungs to collapse causing the manatees to drown. Every winter I spend a good portion of every swim cleaning up trash from the bottom of the river left by uncaring fishermen and boaters. Fishing line and hooks are very dangerous for all the water creatures and almost impossible to remove from the manatee. Please people...Take all you came with including fond memories and GO SLOW FOR THE MANATEES BELOW!
