Drones are being used to track turtles in a bid to boost conservation, scientists say.
The flying machines can follow turtles across large areas and in hard-to-reach locations during the day and also at night.
Dr Alan Rees, an ecologist at the University of Exeter, said the stunning footage gathered by the drones could also boost public interest and involvement in turtle conservation.
"Drones are increasingly being used to gather data in greater detail and across wider areas than ever before," Dr Rees said.
"Satellite systems and aircraft transformed turtle conservation, but drones offer cheaper and often better ways to gather information.
"We are learning more about their behaviour and movements at sea, and drones also give us new avenues for anti-poaching efforts."
However, his study - published in the journal Endangered Species Research - warns that drones cannot fully replace ground work and surveys.
It said more research is needed to understand if and how turtles perceive drones during flight and whether this has an impact on them.
