Orcas seen ramming prey so hard it explodes may be playing game

Scientists believe sunfish-smashing behaviour could be form of entertainment or to help younger whales feed

Orcas have been observed ramming into giant fish so hard that the prey explode, possibly as a form of gory entertainment.

On several occasions, orcas were observed to hold sunfish in their jaws while a second whale smashed into the target at high speed, causing it to break into thousands of pieces. Since the fish had already been killed, scientists suggested the behaviour may represent a form of play.
