Some of the humblest-seeming animals are also the longest-lived, like the tardigrade, or water bear. Being able to withstand desiccation, starvation and extremes of temperature, has contributed towards the success of the tardigrades, which live in habitats from damp moss to flowering plants, sand, freshwater and the ocean. Tardigrades have a unique metabolism that allows them to enter a state of suspended animation. Examples of tardigradetardigrade Like the tardigrades, the rotifers are multicellular animals.
