“Photoswapped: Mum and dads switch heads with their children in freakiest photos you'll ever see. It is a position that many young children would love to be in. And now these strange and sometimes unnerving images show what it would actually be like if babies swapped roles, and heads, with their mother or father. The photos, created by top advertising photographer Paul Ripke, are so eye-catching that they have swept across the world online”. (Photo by Paul Ripke/Barcroft Media via Fame Pictures)

A graffiti, portraying a woman, is seen in Medellin, Colombia on November 19, 2017. Mural graffitis from different artists, street art can be seen in almost every city on Earth, but street arts raw power and potential for change was felt by me most intensively in Medellins Comuna 13, previously one of Colombias most dangerous neighbourhoods, in fact Communa 13 was constant battleground between gangs, narcos, paramilitaries and the government, but today you would hardly recognise it.

“Lofoten Glow”. I was desperately searching a good sunrise spot this particular morning. Normally Storvatnet Lake is completely covered in snow, so you can only imagine my surprise when I saw these crazy ice formations almost being shot out of the frozen lake. I put my crampons on and took a big risk walking out. I could hear the ice cracking underneath my feet, and when you’re all alone in a fjord/canyon like this – the cracks are echoed and sound really frightening. Was it worth it? I sure think so! Photo location: Storvatnet, Lofoten Islands in Northern Norway. (Photo and caption by Stian Klo/National Geographic Photo Contest)

In this Tuesday, September 12, 2017 photo, Amornrat Simapsaisan, a local shop manager, watches before she ate watermelon salad with bamboo worms, at Inspects in the Backyard restaurant, Bangkok, Thailand. Tucking into insects is nothing new in Thailand, where street vendors pushing carts of fried crickets and buttery silkworms have long fed locals and adventurous tourists alike. But bugs are now fine-dining at the Bangkok bistro aiming to revolutionize views of nature’s least-loved creatures and what you can do with them. She tucked in quite happily to her watermelon and cricket salad on a recent evening. “It’s tasty. It’s munchy”, she said. (Photo by Sakchai Lalit/AP Photo)

“These incredible shots show the stunning formations of an iceberg beneath the surface of the ocean. Taken in Tasiilaq, Greenland, by Franco Banfi, the underwater photography captures the beauty of these ice mountains beneath the ocean’s surface. In some of the photos, divers are swimming around an iceberg under the frozen water, while other images show some of the weird and wonderful creatures you can encounter in that part of the ocean”.

With the humpback calving season drawing to a close, here’s a look at some of Rita Kluge’s distinctive marine photos from the south Pacific. The Sydney-based photographer fell in love with whales after witnessing southern rights from the New South Wales coastline as they travelled to and from their feeding grounds in the Antarctic. She has since been to Tonga, where humpbacks breed and calf in winter months, to photograph them in the water. (Photo by Rita Kluge/The Guardian)
