Whale numbers plummet along WA coast
28 Oct
Summary
- Whale migration numbers are at their lowest in decades.
- Fewer than usual calves have been observed this season.
- Scientists cite climate change and krill decline as causes.
The number of whales migrating along Western Australia's coastline has reached its lowest point in decades, prompting significant concern among researchers. Scientists suggest that climate change, reduced krill abundance, and illness may be contributing factors to this alarming trend. The decrease in whale numbers is particularly noticeable in the reduction of calves observed during the migration.
Researchers have noted a substantial drop in whale carcasses washing ashore in recent months, with several incidents along Perth beaches triggering shark warnings. Experts believe there's a correlation between poorer environmental conditions for whales and the increased appearance of deceased animals on shorelines. The unusual migration patterns and signs of poor health in some individuals further emphasize the challenges facing the humpback whale population.
