Tardigrades

Tardigrades or water bears comprise of small (0.1-1mm) multicellular extremophiles found in both terrestrial and aquatic environments. The body is divided into 4 segments plus an head and each segment bears a pair of legs which terminate in claw-like appendages.. The eggs are laid singly or in a shed cuticle the exuvia. Depending on temperature and food availability the life cycle from eggs to adults is usually 3-5 weeks. Water Bears are able to undergo an inactive or cryptobiotic state for many years. to survive harsh environments. Anhydrobiosis is a crytopbiotic phenomena whereby the animals can lose most ot their cellulular water and form a dormant resistant 'tun' which can tolerate extremes of temperature and desiccation. Some genera can also survive unfavourable conditions by entering a dormant diapause phase (encystment) and form black pupal-like structures c.f. Dactylobiotus dispar.
