Volunteers in New Zealand are battling to save up to 200 beached pilot whales stranded near Farewell Spit.
Members of the Project Jonah conservation group have been splashing the pod with water in a bid to keep them cool after they washed up on a 7km stretch of beach.
Already 24 of the whales have died due to the heat.
The Department for Conservation said attempts to refloat the animals and get them back into the sea could only take place during high tide.
Project Jonah said some were successfully refloated on Friday evening.
Farewell Spit has been described as a whale trap because of how often whales have been stranded there.
In January, 36 whales died when a pod became stranded.
Experts say the creatures are confused by the shallow waters and lose their ability to navigate.
