Offshore Killer Whales eating Sleeper Sharks

John Ford and colleagues were observing the whales, they noticed them engaging in feeding behaviour. Immediately following this they discovered chunks of pink meat on the water’s surface which upon genetic analysis turned out to be the meat of at least 16 different Pacific sleeper sharks (Somniosus pacificus).
