Jumping spiders are unique among spiders in that they are able to jump large distances. They use a combination of their long legs and specialized muscles to propel themselves through the air. The spiders have legs that contain a series of muscles that allow them to bend and extend quickly, providing the power for the jump. They also have claws that help them grip surfaces, allowing them to both jump from and cling to surfaces. When the spider jumps, it is actually using its legs like a catapult, pushing off with its legs and then using its claws to grip the surface and stop itself. This process allows the spider to leap up to 50 times its body length, providing them with an excellent way to hunt prey and avoid predators.
