The orca is a large, toothed whale that belongs to the dolphin family. Its black and white colouring makes its unmistakable. Animals swimming under it don't recognise it, because the surface of the water is just as bright as its belly. And from above, you can hardly tell its apart from the sea floor thanks to its black back.
Orcas travel great distances, swimming over 150 km a day to hunt for prey.
