Humpback whales saving other species from orcas found to be common and maybe altruistic

    A team of researchers led by Robert Pitman, a marine ecologist with NOOA Fisheries' Southwest Fisheries Science Center, has found evidence that suggests humpback whales may engage in altruistic behavior during encounters with killer whales attacking other marine species. In a paper available on the open access site Marine Mammal Science, the team describes their analysis of humpback whale encounters with killer whales and why they believe it is possible the whales are intentionally helping other creatures to escape certain death by orcas.

    The research began, the team notes, when Pitman observed a humpback whale come to the rescue of a seal after a pod of killer whales had knocked it off an ice floe back in 2009. Also, another team member had witnessed a group of humpback whales driving off a pod of killer whales that had killed a grey whale pup—they surrounded it and prevented the orcas from eating it for several hours. Such incidents prompted the group to look a little deeper—they conducted searches of both published and unpublished papers detailing humpback observations and discovered among them 115 incidents of humpback whales rescuing other creatures from orca attacks. They noted that just 11 of the incidents involved rescuing humpback whale calves—the rest involved rescuing a variety of other marine creatures such as sea lions, gray whales, sunfish and harbor seals.

    I have had the fortune to study whales for a year or so off the coast of Cali. Orcas were always my favorites, very smart and cunning.
