Blue whales are beginning their migration north to breed, but skinnier than usual animals spotted off Australia's coast are leaving researchers worried about their food source.
abc.net.au/news/blue-whale-study-thin-animals-off-australian-coast-warming-ocean/102316748Researchers are worried "skinny" blue whales spotted off Australia's coast are not finding enough to eat due to warming oceans killing their food.
Chief executive and senior research scientist Dr Peter Gill said his team had spotted more whales than in previous years but the size of some animals observed in recent surveys was concerning. Dr Gill says that while blue whales are "massive animals, they have a thin blubber layer and need to be in feeding areas year-round".
"There's concerns at the moment about the effects of climate change on the wellbeing of this population of blue whales, which are still an endangered species."Blue whales can grow up to 33 metres long and can weigh up to 200 tonnes.
