The Wildscreen festival is the world’s biggest celebration of screen-based natural history storytelling which takes place every two years in Bristol. Here: “Walrus in Midnight Sun”. Walrus feed mostly on bivalves in productive, shallow and often sandy habitats in the Arctic. This individual, though, arrived on a beach outside Tromsø, northern Norway, and found comfort on a stranded dead sperm whale. After two weeks he approached Audun, and only half a metre away he stretched his tusk forward and touched his hand gently. “This was one of the most memorable moments of my life”, Rikardsen says. He named the 500kg male Buddy. After two months, the dead whale was decomposed and Buddy suddenly disappeared. (Photo by Audun Rikardsen/Wildscreen 2016)

Eight year-old Maya Mohammad Ali Merhi walks using prosthetic legs made by her father from tin cans in a camp for displaced people, in the northern Syrian province of Idlib on June 20, 2018. Maya and her father were both born without lower limbs. Unable to afford real prosthetic limbs, her father made her a pair out of tin cans filled with cotton and scrap pieces of cloth. Maya's family had to leave their home in the Aleppo province to flee battles. (Photo by Aaref Watad/AFP Photo)
