Water Bear or Tardigrade
Water bear (or tardigrade). Scanning electron micrograph of a water bear (echiniscus granulatus). These tiny invertebrates live in coastal waters and freshwater habitats, as well as semi-aquatic terrestrial habitats like damp moss. They require water to obtain oxygen by gas exchange. In dry conditions, they can enter a cryptobiotic tun (or barrel) state of dessication to survive. Water bears feed on plant and animal cells and are found throughout the world, from the tropics to the cold polar waters. When in the dessicated state they can survive extreme environments including up to 10 days in the vacuum of space and are classed as extremeophiles. Magnification x2100 (x520 at 10cm wide)

EDITORS COMMENTS
This print showcases the incredible Water Bear or Tardigrade, captured in stunning detail through a scanning electron microscope. The image reveals the intricate features of this tiny invertebrate, known for its ability to thrive in various environments. Water bears can be found in coastal waters, freshwater habitats, and even semi-aquatic terrestrial areas like damp moss. Their survival is dependent on water as they require it for gas exchange to obtain oxygen. However, when faced with dry conditions, these resilient creatures can enter a cryptobiotic tun state of dessication to endure and survive. Feeding on both plant and animal cells, water bears are widely distributed across the globe - from tropical regions to cold polar waters. What makes them truly remarkable is their extreme adaptability. In their dessicated state, they exhibit an astonishing resistance to harsh environments including surviving up to 10 days in the vacuum of space. This has earned them the classification of extremeophiles. The magnified view at x2100 (x520 at 10cm wide) allows us to appreciate every minute detail of this fascinating creature's anatomy - from its barrel-shaped body and foot structure that aids movement across different surfaces. This print by Power and Syred from Science Photo Library serves as a reminder of nature's extraordinary resilience and adaptability displayed by these "moss piglets. "
