The Florida manatee (Trichechus manatus latirostris) is native to Florida and the
Indian River Lagoon. Harbor Branch Oceanographic Institute (HBOI) is located in Indian
River Lagoon and is frequently visited by manatees. The Manatee Project was created in
2009 to document and photograph the manatees visiting HBOI. Analyzing photographs
of 146 manatee that visited HBOI showed that a majority of the injuries sustained were
caused by boats. 97% of the manatee had at least one propeller injury and 31% of the
manatee had at least one skeg injury. Other non-boat related injuries seen in the images
included cold stress and entanglement injuries. This study looked at the prevalence of
scar by anatomical region, the cause of injury, and compared injury locations between
male and female manatees.
