Humpback whales interfering when mammal-eating killer whales attack other species: mobbing behavior and interspecific altruism?

TL;DR: It is suggested that humpbacks initially responded to vocalizations of attacking MEKWs without knowing the prey species targeted, and that humpback mobbing sometimes allowed MEKW prey, including nonhumpbacks, to escape.

TL;DR: The Springer et al. hypothesis that sequential declines occurred in North Pacific populations of harbor and fur seals, Steller sea lions, and sea otters were due to increased predation by killer whales, when industrial whaling's removal of large whales as a supposed primary food source precipitated a prey switch is suggested.
