Spiders foot, SEM
Spiders foot. Coloured scanning electron micrograph of the foot of a garden orb spider (Araneus diadematus). This common spider builds a large web that it uses to catch flying insects. The arrangement of claws on its feet allows the spider to walk as easily on the sticky threads as it does on the ground. The two large grey claws (upper left) are used for walking on hard surfaces. When walking on its web, the spider traps a strand between the sharply-hooked brown claw (centre left) and the curved hairs (orange, lower left). When it releases a thread, the curved hairs push it away from the foot, preventing it sticking. Magnification: x287 at 6x7cm size

Arachnid Arachnida Araneus Diadematus Foot Garden Insectivorous Predator Orb Spider
EDITORS COMMENTS
This print showcases the intricate foot of a garden orb spider, captured using a coloured scanning electron microscope. The garden orb spider, scientifically known as Araneus diadematus, is a common predator that constructs large webs to ensnare flying insects. What makes this spider's foot remarkable is its unique arrangement of claws, allowing it to effortlessly traverse both sticky threads and solid ground. The image reveals two prominent grey claws positioned at the upper left side of the foot, primarily used for walking on hard surfaces. However, when navigating its web, the spider employs a sharply-hooked brown claw located in the center-left region along with curved orange hairs at the lower left corner. By trapping a strand between these structures and subsequently releasing it, the curved hairs effectively prevent any stickiness from impeding movement. At an impressive magnification of x287 and measuring 6x7cm in size, this photograph offers us an up-close glimpse into nature's fascinating world. It highlights not only the adaptability and resourcefulness of arachnids but also their essential role as insectivorous predators within our ecosystem. With its vibrant colors and intricate details, this image serves as a testament to wildlife photography's ability to capture awe-inspiring moments in nature while providing valuable insights into zoology and animal behavior.
