Killer whales are one of the few species of whale that can be found in all oceans around the world. They have a diverse diet and are known to eat fish, seals, penguins, squid, large crabs and even other whales.
While most killer whales prefer colder waters near the poles, some populations have been found in tropical waters close to the equator. It is thought that these killer whales may be seeking out areas with higher prey abundance or possibly warmer water to help with calving.
