Dragging them desperately by their tails, this is the dramatic moment beachgoers leapt into the sea to save around 30 dolphins from certain death.
The rescuers had been sunning themselves on the Rio de Janeiro coastline in Brazil when the dolphins appeared out of nowhere and suddenly beached en masse.
Initially stunned, the sunbathers soon realise the impending danger and race into the surf as the mammals let out piercing squeals of distress.
As this video shows, they make frantic efforts to grab the animals by the tails to pull them into deeper waters.
And it appears their attempts were successful as all the dolphins were rescued to rapturous cheers from onlookers.
I watched this footage holding my breath and thinking how heavy these dolphins must be. Phew! I'm breathing again...
