Hedgehog spine, SEM
Hedgehog spine. Coloured scanning electron micrograph (SEM) of a broken hedgehog spine (yellow). It is surrounded by hairs (brown). The spine is a modified hair made from the protein keratin. Its interior is hollow and crossed with transverse septa, making the spine strong but light. Adult hedgehogs have about 8000 spines, which are used to protect against predators. Magnification: x25 when printed at 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate beauty of a hedgehog spine under a scanning electron microscope (SEM). The image reveals a broken yellow spine surrounded by brown hairs, providing an intriguing glimpse into the world of these remarkable creatures. Hedgehog spines are not ordinary hairs but modified ones made from the protein keratin. They serve as a vital defense mechanism against predators in the wild, with adult hedgehogs boasting an impressive armor of approximately 8000 spines. These spines are both strong and lightweight due to their hollow interior and transverse septa, which crisscross within them. The SEM magnification at x25 allows us to appreciate the fine details of this fascinating structure when printed at 10 centimeters wide. The false coloring applied to this micrograph enhances our understanding of its composition and highlights its significance in protecting these small mammals. This print offers more than just aesthetic appeal; it provides valuable insights into hedgehog biology and zoology. It reminds us that nature has equipped even seemingly delicate creatures with ingenious adaptations for survival. Whether we admire it for its cuteness or marvel at its resilience, this image serves as a testament to the wonders found within our natural world.
