I photographed this picture when I went on a short hike in Georgia forest. The title of the picture came from when I was walking on this narrow path to the lake. The path had leaves all over it and every step felt like I was walking on a soft bed. Photo taken by Wojciech J Kula (United States) - Nature

An Indian Rhino couple shares a moment of intimacy at the Lal Suhanra National Park. The two were brought in from Nepal in 1982, though have yet to produce an offspring. The rhinos are usually apart and grazing far away from the viewing area. However, at this particular time, they not only came closer to us, but shared this beautiful moment.

I captured this image with my Nikon D800 and Tamrom 60mm f2 Lens. This flower has such color and detail. It's almost a flower within a flower. Photo taken by Patricia Isbell (United States) - Nature

I took this picture while visiting a Hindu temple in Pondicherry, India. I had been photographing two cats wrestling in one of the narrow lanes behind the temple when suddenly one of the cats climbed onto the colourful Gopura and sat completely still with its eyes fixed on me. We must have been observing each other for a good ten minutes and I thought I had got some pretty decent shots. The temple cat, probably bored of me by then, turned its back and crouched, as if about to pounce on an invisible prey. I knew something was going to happen, so I got my camera ready and was rewarded with this spectacular leap of faith! Photo taken by Daniel Veenboer (India) - Animals/Pets

The weather forecast for the evening (May 26. 2015) in Trondheim, Norway was promising with a lot of dramatic clouds. I was, however, a little bit anxious on location if it was going to start raining. We could see some lightning in the distance. To clear the equipment from the shooting location takes a good 25 minutes and I didn't want anything to get wet. But we were ok. Roger is a natural talent in front of the camera and It is a treat to portrait him. Photo taken by Sven-Erik Knoff (Norway) - People/Family/Friends

I would have to say that because of this picture i got interested in photography, to be able to capture all the beauty that's around us. This was taken in Thailand, in the island of Ko Pagnan, while I was on holidays in 2009. This view, this picture, the feelings felt while at it, made my trip worth it. The picture has not been manipulated other than resizing. Photo taken by Diego Cedeno (Panama) - Travel/Vacation

The Association of Zoos & Aquariums (AZA) Wild for Wildlife photo contest first runner up winner: So this is a photo representing our orangutans.

It's been a hit at our zoo! Photo taken by Ashley Arimborgo (United States) - Humor

The Association of Zoos & Aquariums (AZA) Wild for Wildlife photo contest Grand Prize Winner: Lemurs can't ring in on Jeopardy. Lemurs have an all-or-none handgrip. This maximizes grip strength, which is perfect for arboreal locomotion (although ring-tailed lemurs spend more time on the ground). Photo taken by Jessa McCauley (United States) - Animals/Pets

I have a hummingbird feeder without any place to sit on, outside my balcony. This little one came and was very thirsty so, it would take a few sips and then hover away from the feeder. Then come back in for more food. Allowed me to capture this. Photo taken by Karamatullah Danyal (United States) - Animals/Pets
