Who's bringing the chips? Otter enjoying a fish supper is just one photo in amazing gallery of wildlife images

By Nick Enoch

A startled otter stares at the lens while enjoying a snack. Meanwhile, a green hairy spider camouflages itself against some foliage... and two flamingos kiss.

These incredible pictures, and more, will be on display later this month when 20 of the world's greatest wildlife photographers gather in London and reveal the secrets of their art.

Hosted by zoologist and conservationist Mark Carwardine and wildlife expert and TV presenter Chris Packham, WildPhotos - the UK's largest wildlife photography show - takes place at the Royal Geographical Society on October 19 and 20.
