What happens if you cut a tardigrade in half?
It is virtually impossible kill a tardigrade. You can freeze it, boil it, crush it, zap it with radiation, and deprive it of food and water—for years! —and it will wiggle back to life.
How much does a tardigrade weigh?
A black bear can be 8 feet long and weigh 500 pounds, but a water bear is microscopic, with no weight established as far as I know. It’s hard to imagine how to weigh them.

What size is a Tardigrade?
about 1 mm
Tardigrades are mostly about 1 mm (0.04 inch) or less in size. They live in a variety of habitats worldwide: in damp moss, on flowering plants, in sand, in fresh water, and in the sea. In adapting to this wide range of external conditions, a large number of genera and species have evolved.

No, at least not to humans. They cannot survive the trip through the human digestive tract since our stomach acid disintegrates the flesh of the tardigrade without much trouble, so eating one wouldn’t do any harm.
Can tardigrades be killed?
Research published in 2020 shows that tardigrades are sensitive to high temperatures. Researchers showed it takes 48 hours at 37.1 °C (98.8 °F) to kill half of active tardigrades that have not been acclimated to heat. Acclimation boosted the temperature needed to kill half of active tardigrades to 37.6 °C (99.7 °F).
What is a tardigrades weakness?
Water temperatures of about 100 degrees Fahrenheit (37.8 degrees Celsius) can kill tardigrades in only a day. As global temperatures rise, that could become a problem for these animals, the authors of the new study said.
How big is a tardigrade compared to an adult?
The biggest adults reach a body length of only around 1.5 mm, while the smallest is less than 0.1 mm. Newly hatched tardigrades may be even smaller than 0.05 mm.

How are tardigrades different from pigs and bears?
However, tardigrades are very different from pigs or bears. Scientists who study how animals are related found that tardigrades are more like insects than pigs, bears, or potatoes. But, they definitely aren’t insects. They are so different from any animal out there, that they have been given their own group name: the phylum Tardigrada.
