Ramazzottius is a genus of water bear or moss piglet, a tardigrade in the class Eutardigrada.

Ramazzottius varieornatus (see image) is a terrestrial invertebrate that is extroardinarily tolerant of extreme conditions such as irradiation, chemicals, dehydration and high pressure. [2] This tolerance is linked to the presence of the damage suppressor protein ( Dsup) that binds to nucleosomes providing tolerance to DNA damage, such as that caused by ionizing radiation or hydroxyl radicals.
