Cape Cod for many years really had only a rare Great White or two, it was not a Jaws fest. Well now it is Great Whites everywhere on the outer shore.
With the waters warming the seals moved north off of the outer shore of Cape Cod. They sit on long sandbars about three feet deep in the water. The seals do not stray to easily into the slightly deeper waters. The great whites will pretend to ignore the seals as they swim by. The seals can out maneuver the sharks. The shark will wait for a moment a seal is not paying attention and then ram the seal to stun the seal. The blood of the seal will rise to the surface as red pool.
This used to never be the case in Cape Cod.
