Jumping spider foot, SEM C014 / 0350
Jumping spider foot. Coloured scanning electron micrograph (SEM) of the tip of the leg of a jumping spider (family Salticidae). In contrast to the 3-clawed foot of web-building spiders, this spiders foot has 2 claws (top centre)and a pad of tufted hair (scopula, centre) that allows it to stick to a wide variety of surfaces. The spiders jumping mechanism is not powered by its leg muscles; instead, muscle contraction in the front of its body causes the legs to extend by hydraulic pressure

EDITORS COMMENTS
This print showcases the intricate details of a jumping spider's foot, taken using a scanning electron microscope (SEM). The image reveals the unique features that enable these agile creatures to navigate various surfaces effortlessly. Unlike web-building spiders with three claws on their feet, this particular species from the Salticidae family possesses only two claws at the top center of its foot. Additionally, it boasts a pad covered in tufted hair called a scopula located at the center. The scopula plays a crucial role in allowing the spider to stick firmly to different types of surfaces. This adaptation provides them with unparalleled versatility and agility when hunting or moving around their environment. Interestingly, unlike other animals that rely on leg muscles for jumping power, jumping spiders use hydraulic pressure generated by muscle contractions in the front part of their bodies to extend their legs and propel themselves forward. The vibrant colors captured in this SEM image bring attention to every minute detail present on this tiny creature's foot. It serves as a reminder of nature's incredible diversity and complexity found even within seemingly small organisms like spiders. This photograph not only highlights fascinating aspects of arachnid biology but also offers an opportunity for us to appreciate and marvel at the wonders of our natural world.
