The incredible photographs show the three alligators crowding around the man’s head as they look directly at the camera and one even appears to sit on his lap whilst another reptile places a claw on his arm as it swims towards the surface. Photographs taken from above the surface show animal handler, Chris Gillette (29) from Fort Lauderdale, Florida, USA holding an alligator out of the water. The images of Chris were taken by Michael Dornellas at the Everglades Outpost Wildlife Rescue, Florida USA. Here: Mich­ael Dornellas brings the beast up close and personal to the camera.

These jaw-some images show what its like to look inside the mouth of a tiger shark. Captured in amazing detail, the unique pictures show the alien-like anatomy of the shark and reveal rows upon rows of razor sharp teeth and white coloured gills. The incredible photographs were taken when a curious shark began to inspect the camera of British born photographer, Adam Hanlon, 46. After sensing electronic impulses omitted by Adams camera, the inquisitive creature began to gently mouth at the cameras housing allowing him capture the unusual perspective.

Photochromes are vibrant and nuanced prints hand-coloured from black-and-white negatives. Created using a process pioneered in the 1880s, these images offer a fascinating insight into the world when colour photography was still in its infancy. A Tour of the World in Photochromes is at the Swiss Camera Museum, Vevey, until 21 August. Here: Street food in the Strada del Porto in Naples, Italy, 1899. (Photo by Swiss Camera Museum/The Guardian)
