…OPSL in collaboration with Josh McInnes of the The Transient Killer Whale Research Project are currently writing a small paper on a very exciting finding. When OM001 and OK008 visited Mirissa on the 25th of November, they decided to chow down on the local marine-life...so what's on their menu? Turns out they like Beaked whale, deep diving and little-understood cetaceans of the Ziphiidae family…Observation details include the orcas feeding on an unidentified object. In two of the images, a beak or rostrum can be seen with a patchy brown/green colouration to the surrounding skin. OPSL contacted Josh McInnes, who specializes in the study of mammal-eating (transient) killer whales of the Pacific Northwest, to offer his opinion on the ID. After looking at the photos, Josh concluded that the beak shape and brown/green colouration (caused by diatoms) appears to be consistent with that of a Blainville’s beaked whale Mesoplodon densirostris.
