Killer Whales (Orca) attacking California Sea Lion

I saw Wild Kingdom in action yesterday: killer whales preying upon California sea lions. Classified as Biggs transient orcas, these individuals are well known (CA51) for terrorizing other marine mammals along the Southern California coast. “Biggs transients” are one of four distinct populations (some insist they are species) of killer whales, characterized by predating upon marine mammals and occasionally sea birds as opposed to ground fish or salmon as do other coastal orcas. Coming upon the five killer whales as they finished toying with and consuming one predation (likely a sea lion), we watched them proceed to take at least two more sea lions over the next hour. In each of the following photos there is a sea lion although in some it is hard to find. The first image depicts the first hit that one of the adult orcas put upon the sea lion. I knew it was coming but still nearly did not get the lens on the sea lion in time. Several other hits took place and the sea lion was clearly panicky and stunned. In the third image, one of the females passes by the sea lion but what is not obvious is that there are two other orcas just below and in front of the sea lion, the pinniped is literally surrounded. There were two subadult orca in the group and it may have been a case of the adults allowing the subadults to learn how to hunt; in practical terms the pack was toying with its doomed prey. In the fifth photo you can see how close to shore this took place. In the final three images, the sea lion is 1) barely able to avoid being pushed under by one of the females, 2) hammered sideways by one of the adults, and 3) gasps for breath before being finally pulled under for the last time and consumed. I don’t photograph killer whales often, but have photographed other whale species including humpback whales and blue whales and some dolphins: Cetacean Photos. For my diving buddies who might be wondering: this was purely a topside trip. Cheers, and thanks for looking!
