There are over 100 recorded incidents where Humpback whales have been trying to protect other whales of their species or completely other species from killer whales, apparently 89% of these incidents involved humpback whales protecting other species. It is interesting question why are these animals behaving like they do. Is it an instinct or are they actually sympathetic towards other species?
