More than 80 false killer whales have died after stranding in the Everglades National Park in Florida during the weekend.
Despite the best efforts of local authorities the whales could not be saved in the remote shallow waters with some caught up in mangroves.
There were thought to be a many as 100 whales in the pod, the fate of the remaining creatures is not yet known.
It is unclear what caused the whales to strand. While false killer whales are know to strand in other parts of the world, such incidents involving this species in Florida are very rare.
