"A giant trophy for a small ant" is what photographer Bence Mate calls this photo. Two leaf-cutter ants are travelling to their nest. One of them is carrying back part of a curly pink leaf - a big trophy for such a small creature. Leaf-cutter ants are one of the strongest species on Earth. They cut and collect leaves which they use as a food source.

This striking photo of a turtle in the Red Sea was taken by Vaclav Krpelik. He said: "I met this big animal when free-diving in the Abu Dabbab bay. It emerged out of nowhere, eating the sea grass and coming right at me. This image captures the precise moment when the turtle decided to come up to the surface to take a breath."
