A group of volunteers joined forces to form a human chain to free four dolphins who were stranded in a canal for four days.
The mammals, a family including two calves, were spotted in the water near the Fossil Park neighbourhood in St Petersburg, Florida, US, on Sunday.
Experts at the Florida Fish Wildlife Conservation Commission (FWC) monitored the dolphins' activity in the past few days in the hope they would swim out with the tide.
But when the dolphins struggled to leave the canal, the brave volunteers joined members of the National Oceanic and Atmospheric Administration and the Clearwater Marine Aquarium to form a rescue team to free them.
