In the state of Florida, there have been 603 leatherback strandings between 1980 and 2014. Almost one-quarter (23.5%) of leatherback strandings are due to vessel-strike injuries, which is the highest cause of strandings. Many human activities indirectly harm "Dermochelys" populations. As a pelagic species, "D. coriacea" is occasionally caught as bycatch. Entanglement in lobster pot ropes is another hazard the animals face.
