Line and buoys wrapped tightly around a humpback whale’s tail. While entanglements may appear straightforward when viewed from the surface, they are often complex and involve many wraps that are not easily removed without specialized equipment. Credit: Pieter Folkens (NOAA Permit # 18786-04).
Right whale #3853 swimming north offshore of South Carolina on Jan. 20, 2011 with a series of fresh propeller wounds running across its back. The whale was observed 5 days previously offshore of Georgia without propeller wounds. It is unknown whether the whale survived its wounds or not, as it has not been re-sighted since. Vessel collisions are a leading cause of right whale mortality. Credit: EcoHealth Alliance (NOAA permit #594-1759).
