A girl paddles on her stand-up board on the waters of Guanabara bay at Bica beach in Rio de Janeiro Brazil, January 10, 2016. Few features capture the beauty, or the problems, of one of the world's most dramatic urban landscapes like Guanabara Bay - the finger-like inlet that forms the shoreline and harbor for Rio de Janeiro. The bay, which carves into southeast Brazil from the Atlantic Ocean, literally gave Rio its name when Portuguese mariners mistook it for a “rio”, or “river”. Four centuries later, the bay is preparing to welcome another sort of seafarer – Olympic sailors, who will navigate the bay when the 2016 Rio Olympics kick off in August.

The buffalo bull charges, on March 23, 2014, in Addo Elephant National Park, South Africa. A young elephant calf tried to attack an old buffalo bull and was taught a lesson it will never forget. The calf was with its herd at a watering hold Addo Elephant National park, South Africa, when the buffalo ventured towards the water. The elephant ran towards the buffalo but the larger animal picked up the young calf and tossed it four metres in the air. Luckily, the elephant was not hurt, but its pride was seriously injured.

A man tries to stop two bulls from locking horns during a bullfight in the eastern emirate of Fujairah October 17, 2014. There are no matadors or picadors, but bulls locking horns with each other draw big crowds to bullfights in the United Arab Emirates (UAE). An hour's drive from the dancing water fountains of Dubai's glitzy downtown, hundreds of fans gather in Fujairah to watch bulls fighting, or perhaps more accurately head butting, with honour rather than money at stake. The UAE sport involves two bulls locking horns in a three-to-four minute Sumo-wrestling-like fight that usually ends with no bloodshed. (Photo by Ahmed Jadallah/Reuters)

In Dougie Wallace’s photos of Mumbai taxis, the chatter, yelling, and constant horns of the city are almost audible. A selection of his images is on show at Gayfield Creative Spaces, Edinburgh, as part of the Retina photography festival until 30 July. For four years, the Glasgow-born Wallace focused his photos on one kind of taxi in particular: the Premier Padmini, a 1960s workhorse painted in black and yellow. Locally known as “Kaali-Peeli”, there were once more than 60,000 of them in the Indian city. But thanks to laws restricting pollution, the cars now are fast disappearing from Mumbai’s streets.

The sport, performed during the four-day “Pongal” or winter harvest festival, is hugely popular in Tamil Nadu. (Photo by Aijaz Rahi/AP Photo)
