Sandrine Kerfante has had a fascination with “doubles” ever since meeting her mother’s twin as a child. In 2012, this lifelong captivation inspired her to create a blog called twin-niwt, which celebrates photographs of doubles in all their forms. “I’m fascinated by the idea of the duo, repetition, symmetry, reflection, mirror games and all the symbolism associated with it”, she says. “I think it’s a topic often present in photography, more or less consciously”.

If you ever wanted to meet a live Pikachu, you might have a hard time finding one. However, there is a creature on this Earth that kind of looks like one. That creature’s name is Thecacera pacifica and it is a species of a sea slug. These little critters can be found in the Indian Ocean from African coast to Indonesia and Vanuatu. Their vibrant orange and blue colors look gorgeous, making it look like some sort of anemone. Also, as you might have guessed from the striking colors of the sea slug, just like most of anemones, this creature is very toxic. Thus, keeping it as a pet isn’t an option.

A boy walks past boats docked at the entrance gate of the fishermen's village in the El Max area of the Mediterranean city of Alexandria September 12, 2014. El Max, where hundreds of boats dart through the canals, has been called the “Venice of Egypt” for its waterways and relaxed atmosphere. Its fishermen, however, worry about how they will make ends meet on meagre earnings they say are being reduced further by polluted waters that are making fishing more difficult. While the government has tried to fix the state's bloated finances by cutting subsidies and reining in spending, some argue the reforms hurt Egypt's most vulnerable who have long relied on a generous system of fuel and food subsidies to supplement low incomes.

Meet the world's smoothest cuddliest hedgehog. Names after brave hero, but Nelson is completely bald so when curled up he looks like an egg. Doesn't have a single prickle or strand of hair. Thought to be suffering a stress related alopecia following a trauma in the wild. Volunteers have been massaging him for half an hour a day for the last year to encourage spikes to grow. Now given up but he still gets daily massages because he enjoys them so much and to keep his cuddle skin soft and smooth. Unlike his namesake Nelson could not defend himself so will live out his days at the Foxy Lodge Wildlife Rescue in Hemsby, England. (Photo by Jeremy Durkin)

In this photo taken Wednesday, December 5, 2018, a woman who scavenges recyclable materials from garbage for a living is seen through a cloud of smoke from burning trash, surrounded by Marabou storks who feed on the garbage, at the dump in the Dandora slum of Nairobi, Kenya. As the world meets again to tackle the growing threat of climate change, how the continent tackles the growing solid waste produced by its more than 1.2 billion residents, many of them eager consumers in growing economies, is a major question in the fight against climate change.

In tiny towns, ballparks, strip clubs, and marijuana dispensaries, officials are setting up shop and offering incentives to entice people who so far have not gotten shots.
