Orcas eat a variety of different prey, including fish, seals, dolphins, sharks, rays, whales, octopuses and squids. But often a pod will specialise in eating just one type of animal. For instance, one pod might have perfected their seal-hunting skills over many generations and focus only on seals, while another pod might be awesome at chasing down salmon, and so they ignore everything else. This makes them "picky eaters".
