Carousel feeding is a hunting technique used by the orca whale population in the waters off northern Norway.[1] Orcas (Orcinus orca) have adapted to life in a variety of environments and their hunting techniques are prey specific. Orcas that utilize the carousel feeding technique prey on wintering herring.[1] This technique, like the majority of orca hunting techniques, involves cooperation. An individual or small group of orcas will herd the herring into a tight ball by releasing bursts of bubbles and/or flashing their white undersides. They then push the herring close to the surface and stun them with tail slaps, allowing the orcas to catch and consume them.[1] The orcas can catch and kill up to 15 herring with each successful slap. It is predicted that the orcas choose to use this hunting technique over others as a response to the behavior of the prey.[1]
