Can tardigrades live in humans?

(Around 43,00 PSI, “most bacteria and multicellular organisms die,” Nature reported.) They’re that tough. If a cataclysm wipes out most of life on the planet — including humans — it’s likely that tardigrades will survive.

Do tardigrades poop?

The little animal has a large dark mass in its digestive tract, about a third of its total length.

Tardigrades live in the sea, fresh water and on land. However, they are difficult to detect: not only are they small — on average, they measure less than 0.5mm in length and the biggest are still less than 2mm — but they are also transparent. “You can just see them with the naked eye,” Mark Blaxter says.
