Tardigrades, also known colloquially as water bears, or moss piglets are a phylum of water-dwelling,eight-legged, segmented micro-animals. They were first described by the German zoologist Johann August Ephraim Goeze in 1773, who gave them the name of “little water bears.” The name Tardigrada (meaning”slow steppers”) was given three years later by the Italian biologist Lazzaro Spallanzani. They have been found everywhere: from mountaintops to the deep sea and mud volcanoes; from tropical rain forests to the Antarctic. Tardigrades are among the most resilient known animals, with individual species able to survive extreme conditions that would be rapidly fatal to nearly all other known lifeforms, such as exposure to extreme temperatures, extreme pressures (both high and low), air deprivation, radiation, dehydration, and starvation. About1,150 known species form the phylum Tardigrada, a part of the superphylum Ecdysozoa. The group includes fossils dating from530 million years ago, in the Cambrian period. Usually, tardigrades are about 0.5 mm(0.02 in) long when they are fully grown. They are short and plump, with four pairs of legs, each ending in claws (usually four to eight) or sucking disks. Tardigrades are prevalent in mosses and lichens and feed on plant cells, algae, and small invertebrates. Credit: Wikipedia.
