The spotting of humpback whales is common in the waters of New York and New Jersey. Tours frequently run from the Rockaways and along the Jersey Shore.

NOAA says humpbacks create bubble clouds to corral their prey and then lunge through the center to swallow the small fish. Fishermen or boaters in these bubble patches run the risk of colliding with a whale as it rapidly approaches the surface.
