Drones are becoming hugely valuable tools for adding to what we know about the creatures of the ocean. We have seen them put to use to watch over killer whales in Canada and track rarely seen shark-chases in all their gory glory. Now researchers have dispatched them to study the behavior of southern right whales and captured a very rare sight – a white calf splashing about off the coast of Western Australia.
Even fully grown southern right whales aren’t so easy to spot. For the last 26 years researchers have been keeping an eye on their populations in the Great Australian Bight, an important breeding ground for the creatures. Though numbers have beensteadily rising, experts say it will still be years before they are removed from the endangered list.
