This year’s contest attracted more than 13,000 submissions from around the world.

Mermaid by Reiko Takahashi. Grad Prix of National Geographic Travel Photographer of the Year Contest, 2018.

The winning image, aptly entitled ‘Mermaid’, was taken by the photographer when she was snorkelling near Japan’s Kumejima Island. Takahashi noted that whilst the calf stayed close to her mom for the most part, there was one point where “the calf began jumping and tapping its tail on the water” close to where she was swimming.
