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.
But still, orcas are dolphins. As a matter of fact, they are the largest of the dolphin species growing to lengths in excess of 30 feet. Next to man, orcas are the most widely distributed mammal on Earth. In all, there are over 80 species of whales living in our world today. These 80 species of whales make up the classification order known as Cetacea. What is a Cetacean? Cetacean is the Latin name for whale.
