Killer whale predatory scarring on mysticetes: A comparison of rake marks among blue, humpback, and gray whales in the eastern North Pacific
Abstract We investigated the predator–prey relationship between baleen whales and killer whales by observing predatory scarring (rake marks) on the tail flukes of three mysticete species from the eastern North Pacific Ocean: humpback, blue, and gray whales. We integrated both qualitative scores and...
