On Wikipedia they say:
Tardigrades occur over the entire world, from the high Himalayas (above
6,000 m), to the deep sea (below 4,000 m) and from the polar regions to the
equator.
The most convenient place to find tardigrades is on lichens and mosses. Other
environments are dunes, beaches, soil and marine or freshwater sediments, where
they may occur quite frequently (up to 25,000 animals per litre). Tardigrades
often can be found by soaking a piece of moss in spring water.[3]
Tardigrades are polyextremophiles
and are able to survive in extreme environments that would kill almost
any other animal. Some can survive temperatures close to absolute zero[4],
temperatures as high as 151 °C (303 °F), 1,000 times more radiation than any
other animal[5], nearly a decade without water, and even the vacuum of space.[6]
If you got everything from a Wild source, I would be willing to bet you have
Water bears, I hope this helps/
