Tardigrades are water-dwelling, eight-legged,
segmented micro-animals.They were first
discovered by the German zoologist Johannes Copyright Disclaimer Under Section 107 of the

August Ephraim Goeze in 1773. The namme
Tardigrada was given three years later by the
Italian biologist Lazzaro Spallanzani. They have
been found everywhere: from mountain tops to
the deep sea and mud volcanoes; from tropical
rain forests to the Antarctic.
Tardigrades are one of the most resilient known
animals, with individual species able to survive
extreme conditions that would be rapidly fatal
to nearly all other known life forms, such as
exposure to extreme temperatures, extreme
pressures (both high and low), air deprivation,
radiation, dehydration, and starvation.
About 1,150 known species form the phylum
Tardigrada, a part of the superphylum
Ecdysozoa. The group includes fossils dating
from 530 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

with four to eight claws also known as "disks"
Tardigrades are prevalent in mosses and
lichens and feed on plant cells, algae, and small
invertebrates. When collected, they may be
viewed under a very low-power microscope,
making them accessible to students and
amateur Scientists.
