Carousel feeding is a cooperative hunting method used by Norwegian orcas (Orcinus orca) to capture wintering Norwegian spring-spawning herring (Clupea harengus). [1] The term carousel feeding was first used to describe a similar hunting behaviour in bottlenose dolphins (Turslops truncatus) in the Black Sea. [2]
Orcas can then release the animal near juvenile whales, allowing the younger whales to practice the difficult capture technique on the now-weakened prey. [92] [94] In the Antarctic, type B orcas hunt Weddell seals and other prey by "wave-hunting".

The duo is well-known among the study’s authors and has been involved in hunting and killing great white sharks for many years. The orcas’ dorsal fins are bent in opposite directions — the ...
Bigg was the first to identify transient orcas as significantly different in eating habits, behavior, and distribution from resident orcas; hence they bear his name. His recommendation in the late 1970s that orcas be placed on the endangered list in Canada fueled interest in protecting the animals throughout the region.
