COCONUT CRAB GOING UP

You have to have the right tools to crack open a coconut, and this fella certainly has them.

The coconut crab is possibly the biggest arthropod on land, with a leg-tip-to-leg-tip length of up to one metre.

It also has extremely strong pincers.

Jan Vermeer's picture was taken on Aldabra, in the Indian Ocean.

"The composition works well in this picture," Jan said. "As the crab walked up, I saw the other trees on both sides. I put the animal in the middle, and that way you put him in his behaviour; you are able to tell a story."

The image was the winner in the Animals in Their Environment section.
