Despite being a very intelligent apex predator with a diverse diet[1], orcas apparently have never killed a human in the wild before in recorded history, and there is only one recorded case of an orca even biting a human[2]. Of course fatal attacks by captive orcas are well known.
Still, orcas are magnificent animals.
