Orcas are called killer whales due to the fact that they are the top predator in the ocean. They are the hunters, not the hunted. They eat almost anything and everything they â¦ can find including other whales.
A wild orca pod can cover over 160 kilometres a day, foraging and socialising. Why are they called âkiller whalesâ when they are dolphins? Dolphins and whales are closely related. Orcas were given the name âkiller whaleâ by ancient sailorsâ observations of groups of orcas hunting and preying on larger whale species.
