Tardigrade. Scanning electron micrograph (SEM) of Stygarctus sp.,a marine tardigrade or water bear. Tardigrades are tiny,segmented animals,0.1-1.0mm in length. They are cylindrical in shape and bear four pairs of stumpy legs,each one terminating in a claw for clinging to sand or soil. Tardigrades live in coastal waters,ditches,lakes and moss clumps on rocks,walls & roofs. Such environments are often subject to drastic temperature changes and dessication. In times of drought tardigrades enter a dehydrated "capsule" state. They can survive for years at a time in this form,swelling up and returning to life when they encounter water.
