Then again, Mac, who knows. Perhaps the alien little fellers were doing some adventurous abducting, took that hapless shark on a whim, and discovered it didn't respond to mind control (didn't have too much of a mind really). Jaws managed to take a few juicy bites out of them while on the treatment table like.
Seeing this particular earthling was too hostile to manage inside a flying disk, they didn't bother to wait until over the ocean, but rid themselves of the danger moving overland.
