Hitching a Ride, Daisy Gilardini, Switzerland
This female polar bear was resting with its two young cubs in Wapusk National Park, Manitoba, Canada, when it suddenly got up and rushed downhill through the deep snow. One of the cubs jumped on to her, holding onto her furry backside with a firm -- and unexpected -- bite.
Opportunistic Croc, Bence Máté, Hungary
After taking this stunning photo, Bence Máté recalls how chilling it was to see the frightening, killing eyes of this 4m-long Nile crocodile. This croc was baited with natural carcasses on an island in the Zimanga Private Game Reserve, South Africa.
Ghostly Snow Geese, Gordon Illg, USA
Snow geese look like ghosts in the pink early morning light as they land among sandhill cranes in the Bosque del Apache National Wildlife Refuge, New Mexico, USA.
A Mother's Hand, Alain Mafart Renodier, France
Photographer A.M. Renodier was on a wintertime visit to Japan's Jigokudani Snow Monkey Park when he took this poignant photograph of a sleeping baby Japanese macaque, its mother's hand protectively covering its head.
Into the Fray, Stephen Belcher, New Zealand
Photographer Stephen Belcher spent a week photographing golden snub-nosed monkeys in a valley in the Zhouzhi Nature Reserve in the Qinling Mountains, China. The monkeys have very thick fur, which they need to withstand the freezing nights in winter. This image shows two males about to fight, one already up on a rock, the other bounding in with a young male.
The Stare of Death, Johan Kloppers, South Africa
The photographer saw this wildebeest calf shortly after it was born in the Kgalagadi Transfrontier Park, South Africa. Little did he know that he would witness its death later that same day; the small herd of wildebeest walked right past a pride of lions and the calf was caught by a lioness and then taken by this male lion.
Head-On, Tapio Kaisla, Finland
Photographer Tapio Kaisla took a trip to Dovrefjell -- Sunndalsfjell National Park, Norway, to find these magnificent oxen amid their natural habitat. Even though spring is not rutting season for these animals, they were already seriously testing their strength against each other and the air rang out with the loud bang of the head-on collision between these two beasts.
The Couple, Sergio Sarta, Italy
During a dive off the coast of Tulamben, Bali, Indonesia, photographer Sergio Sarta was scanning a volcanic, dark grey, sandy seabed when he saw a bright-coloured organism -- a fire urchin with a pair of tiny Coleman shrimps. The fire urchin has quills that are very toxic to humans, and the shrimps avoid this danger by seeking out safe areas between the quills.
Jelly Starburst, Andrea Marshall, USA
Photographer Andrea Marshall was snorkelling off the coast of Mozambique when she came across hundreds of large jelly fish. Many were covered with brittle stars -- opportunistic riders, taking advantage of this transport system to disperse along the coast.
The Stand-Off, Michael Lambie, Canada
It was breeding season, and all the male turkeys were putting on a show for the females, but a number of birds seemed a little confused. This one was more concerned with the potential suitor in front of it, not realising it was its own reflection.
Sisters, Bernd Wasiolka, Germany
Photographer Bernd Wasiolka encountered a large lion pride at a waterhole in the Kgalagadi Transfrontier Park, South Africa. One of the two males spray-marked the branches of a nearby tree. Later two females sniffed the markings and for a brief moment both adopted the same posture.
Into the Night, Karine Aigner, USA
During the summer months, 20 million Mexican free-tailed bats arrive at Bracken Cave in San Antonio, Texas, USA, to give birth and raise their young. Each evening at dusk, the hungry mothers emerge into the night in a vortex, circling out through the entrance and rising into the sky to feed on insects.
The Blue Trail, Mario Cea, Spain
The kingfisher frequented this natural pond every day, and Mario used a high shutter speed with artificial light to photograph it.
Eye in Focus, Ally McDowell, USA/UK
Photographer Ally McDowell often focuses on colours and patterns underwater -- this "pattern" being the eye of a parrotfish.
Spiral, Marco Gargiulo, Italy
Sabella spallanzanii is a species of marine polychaete, also known as a bristle worm. The worm secretes mucus that hardens to form a stiff, sandy tube that protrudes from the sand. It has two layers of feeding tentacles that can be retracted into the tube, and one of the layers forms a distinct spiral.
Eye Contact, Guy Edwardes, UK
The Dalmatian pelican, seen here on Lake Kerkini, Greece, is the largest species of pelican in the world. It is native to eastern Europe, Russia and Asia, however, its population is currently threatened in some areas from hunting, water pollution and habitat loss, particularly a decline in wetlands.
Confusion, Rudi Hulshof, South Africa
Photographer Rudi Hulshof wanted to capture the uncertainty of the future of the southern white rhino in the Welgevonden Game Reserve, South Africa, because of poaching. He anticipated the moment when these two rhinos would walk past each other, creating this silhouette effect and the illusion of a two-headed rhino.
Breakfast Time, Cari Hill, New Zealand
Shortly after purchasing the Giraffe Manor in Nairobi, Kenya, the owners learned that the only remaining Rothschild's giraffes in the country were at risk, as their sole habitat was being subdivided into smallholdings. So they began a breeding program to reintroduce the Rothschild's giraffe into the wild. Today, guests can enjoy visits from resident giraffes in search of a treat.
Caterpillar Curl, Reinhold Schrank, Austria
The photographer was at Lake Kerkini, Greece when he saw this caterpillar on a flower, so he encouraged it onto a piece of rolled dry straw. He had to work fast because the caterpillar was constantly moving.
Rainbow Wings, Victor Tyakht, Russia
In this photo, the bird's wing acts as a diffraction grating -- a surface structure with a repeating pattern of ridges or slits. The structure causes the incoming light rays to spread out, bend and split into spectral colours, producing this shimmering rainbow effect.
Monkey Ball, Thomas Kokta, Germany
Cold temperatures on Shodoshima Island, Japan, sometimes lead to monkey balls, where a group of five or more snow monkeys huddle together to keep warm. The photographer climbed a tree to get this image.
Facing the Storm, Gunther Riehle, Germany
Gunther Riehle arrived in Antarctica during sunshine, but by the evening a storm picked up. Initially just strong winds, by the early morning snow had arrived. He concentrated on taking images of the emperor penguin chicks huddled together to shield themselves from the force of the snowstorm.
