Are Tardigrades Dangerous?
No, at least not to humans. Other micro-organisms in their environment should be on notice though; those claws aren't for show. While most tardigrades are herbivorous, not all of them are, and they will eat you if you are smaller than they are and you are within reach of their claws.
Despite their reputation, tardigrades aren't entirely indestructible. 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. So far, no one has reported a case where a disease or infection was introduced into the human body via tardigrade, and they aren't parasitic. It's possible that they might try to suck out the contents of one of the individual cells that make up our body if they ever came into contact with it, but we've got trillions more. Getting eaten alive by tardigrades just isn't something that's going to ever happen.
