Video: Scientists watch orcas ram a sunfish so hard it explodes

Orcas are known for surprising behaviors. A new study documents two cases of orcas ramming sunfish so hard that the fish explode.

Marine biologists off of Baja California recorded one orca teeing up another to smash a sunfish into pieces. Scientists say there could be a reason for this behavior — or it could be just for entertainment.
