We know that spiders can climb up walls and across ceilings. But what about glass? It seems like a difficult task for such small creatures, but they’ve managed to do it! Scientists have discovered the secret of how spiders manage this feat: lots of little hairs on their feet are coated with tiny ‘hairs’ called setae. They use these tiny setae to cling onto the surface of glass as they walk or run over it.

Spider’s long, skinny legs are covered in tiny hairs called setae. The tips of the setae can stick to surfaces like glass as they walk or run over it. The setae also help them climb smooth surfaces like wood, glass and metal. It’s not just the hairs that give spiders this ability – they have claws too.

The claw-like tips of their legs can grip onto an even smoother surface than a flat one. When climbing up sheer walls or ceilings, spiders need to use this combination effect: sticking with thin feet for small gaps in between big spaces; using claws for bigger and more obvious crevices.

Claws are sharp hooks (or other tools) on spider’s body which helps it cling onto surfaces when climbing. Spider has special structures called “setae,” tiny hair-like projections from its footpads that stick to things such as mites, plants and leaves.
