There are just hours to go to submit your most spectacular and creative visions of wildlife caught on camera to the 50th Wildlife Photographer of the Year competition. It closes at 12.00 GMT on Thursday 27 February. So enter now.
This year's competition saw a simpler set of subject and photographic categories introduced as well as new awards. So far there have been tens of thousands of entries from around the world, with a lot of interest in the new TIMElapse and portfolio adult categories as well as the WILD-I category for young smartphone photographers.
Magic mushrooms by Agorastos Papatsanis. Agorastos spotted these two parasol mushrooms growing in woodland in Greece's Grevena region. 'Nature is the true designer,' he says of his fairytale shot, taken with double exposure, in-camera.
Here are some words of advice from the WPY team for last-minute entrants:
'We want to see outstanding shots of any species, like these three 2013 award winning images pictured here. Photographs that depict the familiar to the less well known, the widespread to the endangered, the charismatic to the overlooked, and the urban to the wild.
Grand raven by Chris Aydlett. This is a perfect example of a familiar subject presented in an original, dramatic way. Using the strong midday light, Chris created the shot in black and white, to give the scene impact and boost the metallic gloss of the raven's plumage.
'Our competition judges, as ever, are looking for fresh, creative images that reveal the diversity, majesty and beauty of life on Earth. As well as those that highlight the fragility of the natural world.
Feast of the ancient mariner by Brian Skerry. Brian's vivid underwater shot shows the elusive leatherback turtle feasting on a free-floating colony of tiny tunicates (sea squirts). It's a rare portrait of an incredible surivor.
'It doesn't matter where you take your shot. It could be in a garden or car park, underwater or in a remote corner of our planet. Just take a closer look and share your vision with us, wherever you are. There's still time. And good luck!'
The first round of the judging for the 50th competition entries starts on 10 March.
