Although resident orcas have never been observed to eat other marine mammals, they occasionally harass and kill porpoises and seals for no apparent reason. [105] Some dolphins recognize resident orcas as harmless and remain in the same area. [106] Orcas do consume seabirds but are more likely to kill and leave them uneaten.

The herring population is not completely depleted by orcas because they never eat the whole herring ball during the feeding phase of carousel feeding.
