Foot and Thistle, Mountain Gorilla of Rwanda. I was fortunate to visit the rare and endangered Mountain Gorillas in Rwanda, February of 2010. This young gorilla had fallen asleep with a thistle grasped in his foot. The thistle is one of their food sources. They learn to extract the pith from the spine-defended inedible stem. This particular gorilla demonstrates syndactyly of the third and fourth toes, a common congenital malformation also found in humans. (Photo and caption by Jim Edwards) #

Surva, the International Festival of the Masquerade Games held in the town of Pernik, Bulgaria is the biggest event of this type not only in Bulgaria but on the Balkan Peninsula as well. It promotes variations of ancient Bulgarian customs that are still alive today. These are an important part of the Bulgarian folklore tradition and are meant to be performed by single men and women. With its competitive nature, the festival is not only a venue but also a contest for the living vessels of this tradition, namely the Kukeri and Survakari. (Photo and caption by Orlin Ognyanov) #

Ki Gompa. This picture was taken when I visited the Buddhist Monastery of Ki. Ki is a tiny village in the middle of the Himalayas, and next to it is Ki Gompa (Ki Monastery). I lived with the monks for about a week, and this picture reflects the peaceful, almost heavenly atmosphere that characterizes this place. The Monastery is almost 4,000 meters high, and I had to climb almost 500 meters more to get this panorama. This place is a touch of heaven. (Photo and caption by Natalia Luzuriaga) #

Haunting Glimpse. An encounter with an elusive Canada Lynx is said to be a rare privilege. I am honored to have had the opportunity to see a Lynx up close and personal. As I photographed this beautiful cat, I felt transfixed by its wild, untamed, haunting eyes. This is a once in a lifetime chance that I will cherish forever. (Photo and caption by Janet Chester) #

Suradita Village, West Java, Indonesia. Children playing with their roosters. Actually it was not a real cockfight because the roosters didn't wear blades on their feet. Children like to play this game because they almost never have toys in their life. (Photo and caption by Ario Wibisono) #

North Atlantic seals enduring winter storm. It was already -1 and with a strong wind it was colder still, Had to position myself so as to shield the camera from the wind to keep the image sharp the snow was being blown horizontally away from me. (Photo and caption by Eric Garnett) #

Great Blue Heron with fish. The largest and most widespread heron in North America. When foraging, they stand silently along riverbanks, lake shores, or in wet meadows, waiting for prey to come by, which they then strike with their bills. (Photo and caption by Linh Dinh) #

A walk along the river bank. This photo was taken in Zhenyuan, Guizhou Province, China this summer. I was taking a walk along the river bank of Wuyang in the mist of a late afternoon shower. Refreshing smell after rain was mixed with the aroma from nearby food stands. In the distance, kids were playing and laughing. The tranquil and harmonious life of the local people reminds me of the joyful time I grew up in a similar small town in Southwest China. (Photo and caption by Fred Wang) #

Heavy load. One morning in August, I was on my way to pick up the newspaper. Everything was moist and wet, and I spotted this little fly on a small white flower, just outside my bedroom window. Two hours after I shot this picture I went outside again, and the fly was still sitting on the same flower - still not able to fly. (Photo and caption by Audun Wigen) #

Table Mountain. I took this picture in June 2009 while I was just outside of Cape Town, South Africa. I was working at a kids camp and took a quick shot of the sun setting over Table Mountain as we were headed in for dinner. I was in such a rush to capture the sunset while trying to keep an eye on a bunch of kids on the playground that I didn't even notice the boy in the right edge of my viewfinder. It wasn't until I was back home in Tennessee that I discovered the huge impact of this picture. The duality of the not-quite-teenage boy and the 260-million-year-old mountain in the same shot absolutely amazed me. (Photo and caption by Quinn Ballard) #

After the Crash. My dear friend, Laura, fell from the sky. The helicopter she was traveling in crashed into an open, dry field and burst info flames, killing three of the six passengers on board, including the pilot. Laura survived, but barely. She was burned, crushed, and near death. She broke 45 bones. She was pulled from the burning wreckage by her hair. To this day, she still cannot walk. While there wasn't a part of her body that was unharmed, her spirit and determination to live a full, happy life remains stronger than ever. This image taken in a lush, green field is meant to signify her rebirth. (Photo and caption by Judy Starkman) #
