Three humpback whales jumped out of the water in unison in Cape Cod in front of stunned onlookers on Monday, 24 July.<br /><br />Extraordinary footage captured by Robert Addie shows the huge creatures breaching at the same time off the coast.<br /><br />According to the Ocean Conservancy nonprofit, scientists suspect that humpback whales exhibit this behaviour as a way of communicating; it is believed that slapping their fins on the surface sends messages to other whales.<br /><br />“It’s once in a lifetime. Just very fortunate. I feel God shined down on me to allow me to capture that,” Addie told CBS.
