Boat strikes of marine animals are increasingly common, for obvious reasons. It is disappointing to observe a marine animal severely or mortally wounded by a collision with a boat. We have encountered several marine animals bearing unmistakable boat propeller scars:
| North Pacific humpback whale showing extensive scarring, almost certainly from a boat propeller, on dorsal ridge. Maui, Hawaii, USA.
Species: Megaptera novaeangliae
See usage restrictions
| Ocean sunfish injured by boat prop with cleaner fishes, open ocean, Baja California.
Species: Mola mola
| Gray whale dorsal aspect showing injury/wound/indentation likely caused by boat, Laguna San Ignacio, Baja California.
Species: Eschrichtius robustus
| West Indian manatee. Three Sisters Springs, Crystal River, Florida, USA.
Species: Trichechus manatus

The humpback whale photograph was taken during Hawaii Whale Research Foundation research activities conducted under provisions of NOAA / NMFS and State of Hawaii scientific research permits.<
