Rescue teams said about 200 whales have died and only 35 are still alive after a mass stranding in Australia this week.
Pilot whales were found Wednesday stranded on an open beach along the Tasmanian coast.
Rescue efforts are underway to save the remaining whales.
“This morning we are mainly focused on getting into and getting this rescue operation [the whales] Brendon Clark of the Tasmanian Parks and Wildlife Service told the Australian Broadcasting Corporation on Thursday.
“We are aware that some of them may be returning the beach so we will monitor that.”
Rescuers had previously estimated that about half of the whales were still alive.
This is the second mass stranding of whales to occur in Tasmania this week after more than a dozen sperm whales, mostly young males and believed to be part of the same bachelor whale, were found dead on another beach.
Cases of stranding whales have baffled marine scientists for decades.
The largest rims were in Tasmania in 2020 when more than 450 pilot whales were found.
