You might feel as if you are being watched when you look at these incredible pictures – revealing the close-up world of a spider's eyes. The intimidating creatures, which look like they should live in a horror film, star menacingly at the camera as every fleck of colour and hair are revealed. But despite their appearance the arachnids are actually jumping spiders, which measure a tiny six millimetres in length. The harmless arachnids, which are capable of jumping up to six times their own height, can be found in grassy meadows and on the walls of houses on sunny days. (Photo by SWNS/ABACA Press)

Irina, worker of a petrol station, now member of reconnaissance team of pro-Russian rebels' in the town of Makievka, eastern Ukraine, October 6, 2014. Like the men in the conflict, the women come from all walks of life. Some women come to serve with their husbands and boyfriends, others are single. Female fighters on both sides said the men in their units treat them as equals, though sometimes showing more leniency. They have little respect for men who have not taken up arms. On both sides the fighters expect a long conflict, despite the fragile ceasefire now in place. (Photo by Shamil Zhumatov/Reuters)
