Humpback migration off WA coast prompts questions over fin-slapping behaviour

ABC  

Winter is the annual season for humpback whales to migrate north along Western Australia's coast to breed in warmer waters, but those lucky enough to spot them may have a few questions about their behaviour. Dr Kate Sprogis, a marine biologist specialising in cetaceans, such as whales and dolphins, said humpback whales, in particular, were a very "surface-active" species. "So you'll commonly see splashes on the water, say, if you're watching from land or you're on a whale-watch boat," Dr Sprogis said. "A lot of time when you go on the surface on a boat after several breaching events of a whale, there will be floating dead skin cells, skin pieces on the water," Dr Sprogis said. "People think we know a lot about whales, but when you actually think that we don't even know about a humpback whale's heartbeat, we actually don't know very much at all."
