Wildlife Photographer Of The Year 2013: The Most Spectacular Pictures Of The Natural World

An adorable dugong surrounded by curious snorkellers, a crocodile battling with a green turtle and rain-soaked bedraggled lions in the Serengeti – these are just some of the stunning images released from this year's Wildlife Photographer of the Year.

As the prestigious competition comes to a close – having attracted almost 43,000 entries from 96 countries – 100 of the best pictures are set to go display at the Natural History Museum in London.

Entries are submitted in a variety of categories each year, with three categories aimed at photographers aged under 18.

Thousands of pictures are then judged by industry experts and the overall winner is announced at a ceremony at the Kensington museum in October.
