 This photo won thirteenth place in the Microscopic Photography Competition 2024, and it is a close-up photo of the eyes of the green crab spider, Diaea dorsata, which is one of the smallest types of crab spiders. Females can reach 6 mm in length, and males can reach 4 mm. Captured by Pavel Blachowicz at 20x magnification The eyes of any living organism are adapted to its environment, diet, and survival. Humans have two front eyes for stereoscopic vision, which enhances depth and distance perception, while many spiders have multiple eyes (usually eight), some of which are large in size, for powerful vision. Some of them are small for peripheral vision. Each pair of eyes is specialized in specific tasks, such as detecting movement, capturing prey and focusing on it from different angles, or fleeing and avoiding predators surrounding it from every direction, even in low light. Unlike humans, who see a wide range of colors, a spider's vision often tends toward a more limited range. Many spiders are sensitive to ultraviolet light, which opens up a unique dimension of visual information. This adaptation aids in tasks such as locating silk threads, detecting mating pheromones, and identifying prey that may be camouflaged in the ultraviolet spectrum. In the case of this spider, its multi-eyed visual system increases its ability to detect predators and prey across its environment, enabling it to survive.
