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.
Some animals that have the word fish in their names are not really fish. Some examples are cuttlefish (they are mollusks, see below), jellyfish (they are actually plankton), and starfish (they belong to a group called echinoderms). Orcas are also called Killer Whales because they are very active hunters. 2  They eat large animals such as fish and marine mammals like seals or even other kinds of whales! 3  Sperm whales are among the few animals large enough to catch and eat giant squid.
