Killer whales are also the only known predator of great white sharks. They feed on fish and squid like other toothed whale species, but will also target seals, sea birds and even other whale species - even if they are far bigger than themselves. Killer whales are apex predators, meaning they are at the top of their food chain. Killer whales, the largest dolphin species, also have teeth, but their diet is different to other odontocetes. Humpback and Bryde's whales also actively hunt for small schooling fish such as herring and anchovies.
All of them feed on krill, but sometimes include other sea creatures in their diets, such as copepod crustaceans and small fish. Right, minke, fin and sei whales also have baleen plates. They then push the water back out using their baleen plates as a strainer, keeping the food in their mouths. The blue whale has one of the largest appetites of any animal, eating up to four tonnes of krill every day.īlue whales, which have baleen plates, feed by taking huge mouthfuls of water and food. These tiny animals are found in all of Earth's oceans, swimming in massive swarms, sometimes of more than 30,000 individuals.
These colossal cetaceans often reach 30 metres in length and can weigh up to 180 tonnes - so they need to eat a lot to keep them swimming.īut despite their enormous size, blue whales feed almost exclusively on krill - small, shrimp-like crustaceans that grow to about six centimetres. Blue whales are the largest animals ever to have lived.
