Todd Bretl specializes in underwater photography, and is able to capture striking photos of aquatic life big and small. His photos of sharks are particularly striking; though he rarely faces hostility from the animals, he tries not to spend too much time looking through his viewfinder and many shots are framed by educated guesses and impeccable timing. What follows are photographs taken over the past several years on trips to the Bahamas and Isla Guadalupe, an island off the coast of the Baja California peninsula in Mexico. (Photo by Todd Bretl)

“This is the terrifying moment a diver came head to head with a shark as it swims inches away snatching a bite for dinner. The close encounter, captured off Bimini Island in the Bahamas, shows the hammerhead approaching diver Eli Martinez who bravely stands his ground as the giant beast approaches. Eli, free diving outside of a protective cage, carefully handled the sea creature despite its menacing razor-sharp teeth – but admitted they are extremely shy and need a lot of work to allow divers close to them. After multiple trips and hours of diving nearby they finally got used to Eli in January this year – hammerheads regularly visit these waters during the winter season”. – Caters News.

These are the chimp-ly marvellous images captured by a cheeky monkey after turning the tables on a photographer who left his camera unmanned. The inquisitive scamp playfully went to investigate the equipment before becoming fascinated with his own reflection in the lens. And it wasnt long before the crested black macaque hijacked the camera and started snapping away sending award-winning photographer David Slater bananas. David, from Coleford, Gloucestershire, was on a trip to a small national park north of the Indonesian island of Sulawesi when he met the incredibly friendly bunch.

An approximately 8 year-old male orangutan named Siamang reacts under the influence of tranquilizer as it's being prepared to be released into the wild at a rehabilitation center in Kuta Mbelin, North Sumatra, Indonesia, Friday, July 10, 2015. The orangutans at the center were mostly rescued from palm oil plantations or confiscated from homes where they were kept as pet animals. Orangutan populations in Indonesia's Borneo and Sumatra island are facing severe threats from habitat loss, illegal logging, fires and poaching. Conservationists predicted that without immediate action, orangutans are likely to be the first great ape to become extinct in the wild. (Photo by Binsar Bakkara/AP Photo)
