French photographer Florian Ledoux took the winning photo, entitled Above the Crabeater Seals, in Antarctica.
“For me, it is very important to show the state of the Arctic and Antarctic regions,” he said.
“It is also important that anyone inspired by this style of drone image understands the importance of wildlife, and being ethical in your approach.
“Ensure that your drone does not spook animals or disturb them, and always conduct yourself within accordance of local regulations.”
Mr Ledoux beat 7,000 other entries from 117 different countries to win Nature TTL Photographer of the Year 2020.
Here are other category winners and runners-up in the competition, with descriptions by the photographers.
