Description
Water bear (Echiniscus granulatus). Color enhanced scanning electron micrograph (SEM) of a water bear in its active state. Water bears (or tardigrades) are tiny invertebrates that live in aquatic and semi-aquatic habitats such as lichen and damp moss. They require water to obtain oxygen by gas exchange. In dry conditions, they can enter a cryptobiotic state of dessication, known as a tun, to survive. In this state, water bears can survive for up to a decade. Echiniscus granulatus is a herbivorous species that feeds on moss cells. This specimen originated from moss samples in Tubingen, Germany. Water bears are found throughout the world, including regions of extreme temperature, such as hot springs, and extreme pressure, such as deep underwater. They can also survive high levels of radiation and the vacuum of space. Magnification: x585 when printed 10cm wide.
