No, orcas don't have any natural predators but instead, they are predators that hunt and kill other animals. Orcas are known as killer whales and they can hunt in the dark even if they cannot see their prey. Killer whales use their sonar inside of their brains to hunt and kill their prey in the dark. Orcas are apex predators and no other predators can kill apex predators.
if the orcas are alone yes but if there in a pod than the sperm whale would lose
People used to, but fishing for blue whales was banned long ago. Orcas will attack blue whales, but can't kill them. Aside from orcas, there's nothing out there that will mess with a blue whale - they weigh 150 tons and are very fast.
