Orca

The orca or killer whale is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. It is the only extant species in the genus Orcinus and is recognizable by its black-and-white patterned body. There are three main types of killer whales in the North Pacific: Resident, Transient, and Offshore. Each ecotype differs in appearance, diet, habitat, genetics, and behavior. While all three types share at least part of their habitats, they are not known to interbreed with each other. Killer whales are apex predators, which means they have no natural predators. They hunt in packs, much like wolves, which are also at the top of their food chain. It feels rubbery to touch but is very sensitive. Orcas like to rub their bodies on each other and even scratch each other by raking their teeth over different areas. This means their bodies are often scored. Depending on the season and where they are, their diet varies—some orcas eat more fishes and squid than seals and penguins. But wherever they are in any of the world's oceans, average-sized orcas may eat about 500 pounds (227 kilograms) of food a day.
