• Fish-eating killer whales prey on around 30 species of fish, particularly salmon,
herring, and tuna. In New Zealand, rays are killer whales' most frequent prey,

undersides. They then slap the ball with their tail flukes, either stunning or killing
up to 10–15 fish at a time. The herring are then eaten one at a time. Carousel
feeding has only been documented in the Norwegian killer whale population and
with some oceanic dolphin species
