I went to the Wildlife Photographer of the Year exhibition at the Natural History Museum this afternoon. The standard, as usual, was exceptionally high, but the overall winner, a beautiful, moment-frozen-in-time photograph taken from a hide on the Mississippi river of a giant crocodile dragging a surprised fisherman into the water was absolutely stunning.

Highly Commended in the Animals In Their Environment category was a tongue-in-cheek shot of a freezer cabinet full of frozen turkeys, which apparently impressed the judges with its "wit and sensitivity".

The winner of the Young Wildlife Photographer was a beautifully composed shot of two stray dogs copulating in an overturned wheelie bin. The photographer, just nine years old, had apparently spent an entire weekend waiting for the perfect moment.
