The comparative sizes of this humpback whale, its calf and the diver who is photographing them do not suggest that man could be the first predator of the gigantic mammal. It is however the case because of fishing but also of the pollution he generates. Among its marine congeners, the main threat to whales is the orca or killer whale (Orcinus orca), whose bites mark the bodies of many humpback whales and from whom the mothers protect their juveniles.
