These camera tags would stay on each whale for 24 to 48 hours, allowing researchers to experience a day in the life of a whale."We have been able to show that whales spend a great deal of time during the days socializing and resting and then feeding largely throughout the evening and night time," lead scientist Ari Friedlaender, an ecologist at Oregon State University, said in a statement.To become a premium (GOLD) member for life and unlock this feature, all you have to do is buy any amount of tokens one time!
Researchers have gained a whale's-eye view of the marine mammals' lives in Antarctica, thanks to a research project that placed noninvasive digital tags — containing sensors and a camera — on minke and humpback whales.
Video of the whales diving for food also reveals the relative size of krill, and the density of the krill patch, that the whales are feeding on.
This information can help with whale conservation efforts because beyond the impacts of climate change, an increase in krill fishing can also threaten the whales, said Chris Johnson, ocean science manager for WWF-Australia."Once we have an idea about where the whales feed, how often, where they go and rest, we can use this to inform policy and management to protect these whales and their ecosystem," Friedlaender said.
