Water bear, SEM C016 / 9083
Water bear (Echiniscus granulatus). Coloured scanning electron micrograph (SEM) of the head of a water bear, or tardigrade (phylum Tardigrada). Water bears are small, water-dwelling, segmented micro-animals with eight legs that live in damp habitats such as moss or lichen. They are classed as extremophiles as they can survive dry conditions by changing into a desiccated state, in which they can remain for many years. Whilst in this form (known as a tun) they can withstand the most extreme environments and can tolerate radiation levels as high as x1000 more than other animals, including humans. They have even been brought back alive after spending 10 days in the vacuum of space. Magnification: x100, when printed at 10 centimetres wide

EDITORS COMMENTS
This print showcases the incredible world of microscopic organisms, specifically focusing on a water bear, also known as a tardigrade. The image, taken using a scanning electron microscope (SEM), provides an up-close view of the head of this fascinating creature. Water bears are minute creatures that inhabit watery environments such as moss or lichen. With their segmented bodies and eight legs, they navigate these damp habitats with ease. However, what truly sets them apart is their remarkable ability to survive in extreme conditions. When faced with dry environments, water bears can enter a desiccated state called a tun. In this form, they can endure harsh surroundings for many years and even withstand radiation levels thousands of times higher than other animals. Astonishingly, they have been known to return alive after spending 10 days in the vacuum of space. The magnified image reveals intricate details like its limbs and claws while showcasing its vibrant colors against a white background. This photograph not only highlights the beauty found within nature's smallest creations but also serves as a testament to the resilience and adaptability exhibited by these micro-animals. With its scientific significance in fields such as zoology and microbiology, this stunning print offers viewers an opportunity to marvel at the wonders hidden within our natural world – reminding us that even in seemingly inhospitable conditions, life finds ways to thrive.
