As I understand it, the seawater crocodile does not navigate when
sea; it drifts with the current. All crocodiles rely on stealth to
approach potential prey. They need muddy/occluded water and only
inhabit rivers, estuaries, swamps and the like. So the predation
rate in the clear waters of the marine littoral would be negligible.
