An exterior view of Rauceby, an abandoned mental asylum in Lincolnshire, UK. These haunting photos show the collapsing remains of a derelict mental asylum. The pictures show the ruined former hospital building and chapel, now covered in dust and graffiti. Few signs remain that reveal the site as a former home of mentally ill adults and children.

There is nothing more endearing than seeing true friendship and love. Especially, if it as improbable as that of a big dog and a tiny kitten. Somehow, animals feel when they are dealing with a baby. For example, no matter how much a toddler will tug on the tail of a cat and play roughly with it, it will never or very rarely fight back. This set of pictures taken by Jessie Pon shows a tiny kitten mistaking an adult golden retriever for his mother. Though it may hurt the dog’s nose with its sharp claws, the dog does nothing to harm the kitty. On the contrary, it’s watching over the kitty-cat as if it were her own puppy. (Photo by Jessie Pon)

With their affinity for hunting, sneaking, and hidden blade-like retractable claw, cats are really the assassins of the animal world. They're not as intimidating when they're kittens dressed up as assassins from the upcoming Assassin's Creed Unity, but what they lack in deadliness they more than make up for in cuteness. YouTube user Mr.TVCow posted the video, in which four hooded kittens hunt down a french soldier, much like like in a number of trailers for Assassin's Creed Unity. They use their eagle vision ability, parkour after their target, and perform lethal aerial assassinations, and yes, it's as unbearably adorable as it sounds.

The photography duo of Floto+Warner created the series, “Colorant”, from an idea that stemmed out of a previous series and the fascination of landscapes, with results that leave one in awe. Creating shapes, not experienced in nature, they tossed colored water in the air to capture “a momentary graffiti of air and space”. Using a high shutter speed to capture these fleeting moments, Floto/Warner has produced a multi-medium series with jaw-dropping results. Photo: “Orange Salt Flats”. (Photo by Floto/Warner)

KidZania provides children and their parents a safe, unique, and very realistic educational environment that allows kids between the ages of four to twelve to do what comes naturally to them: role-playing by mimicking traditionally adult activities. As in the real world, children perform “jobs” and are either paid for their work (as a fireman, doctor, police officer, journalist, shopkeeper, etc.) or pay to shop or to be entertained. The indoor theme park is a city built to scale for children, complete with buildings, paved streets, vehicles, a functioning economy, and recognizable destinations in the form of “establishments” sponsored and branded by leading multi-national and local brands.

The sea otter (Enhydra lutris) is a marine mammal native to the coasts of the northern and eastern North Pacific Ocean. Adult sea otters typically weigh between 14 and 45 kg (31 and 99 lb), making them the heaviest members of the weasel family, but among the smallest marine mammals. Unlike most marine mammals, the sea otter's primary form of insulation is an exceptionally thick coat of fur, the densest in the animal kingdom. Although it can walk on land, the sea otter lives mostly in the ocean.

A stork-billed kingfisher (Pelargopsis capensis) is seen perched on a tree during monsoon rain on July 25, 2016 in Bintan, Indonesia. The stork-billed kingfisher is a tree species which is widely but sparsely distributed in the tropical Indian subcontinent and Southeast Asia, from India to Indonesia. This kingfisher is resident throughout its range. It is very large, measuring 35 to 38 cm (14 to 15 in) in length. The adult has a green back, blue wings and tail, and grey head.

In this photo illustration, an endangered Chinese box turtle which hatched at Bristol Zoo is placed on a box of matches on August 12, 2008 in Bristol, England. It weighs just 15 grams and measures around 4cm long whereas an adult box turtle weighs around 800 grams, measures around 16 cm long and can live up to 50 years. Chinese box turtles are hunted for their meat for use in medicine or as pets and have been listed as endangered on the International Union for Endangered Species Red List.
