The term 'ocean predator' refers to animals that hunt and feed on other creatures in the ocean. Two of the most common ocean predators are the ORCA (also known as the killer whale) and the SHARK. The ORCA is a large, toothed whale that can be found in all oceans around the world. Sharks are also found in all oceans and come in many different species, including the hammerhead SHARK. Hammerhead sharks are easily recognizable due to their unique head shape.
