How does Loeb’s Study help readers better understand the durability of water bears?

Terrestrial species live in the interior dampness of moss, lichen, leaf litter and soil; other species are found in fresh or salt water. They are commonly known as water bears, a name derived from their resemblance to eight-legged pandas. Some call them moss piglets and they have also been compared to pygmy rhinoceroses and armadillos. On seeing them, most people say tardigrades are the cutest invertebrate.
