Orcas are commonly known as the largest type of dolphin or at the top of the food chain. They hunt in pods from prey as small as herring to the huge blue whale. They also eat other animals seals, penguins, sea lions, and other cetaceans. Orcas near the North and South Poles have been known to create large waves knocking their pray off icebergs. Some orcas in Argentina have been known to beach themselves catching seals on the beach. As the top predator of the oceanic food chain, these intelligent toothed whales have no natural predators. Depending on the ecotype and where their live, males live between 40-60 years old while females tend to live from 60 to even 100 years old.
