I did not realize that tardigrades were so small. Previously I thought one would be able to see one with the naked eye.

Most species grow to half a millimetre. So they're just barely visible to the naked eye; like a small spec of dust.

That would be mildly terrifying

Being naked isn't that scary

I'm not a biologist but there is no way in hell that a virus can be as big as a living organism right? That's probably not a bacteriophage

[–] [email protected] 12 points 1 month ago

Definitely not, a bacteriophage is like 500 nanometres. A tardigrade is 0.5 mm, or 500 000 nanometres, literally 1000x the size.

I am a microbiologist, there's no way in hell that's a virus.

Edit: it's probably a radiolarian skeleton, maybe genus cornutella.

Edit 2: it's indeed a cornutella skeleton: https://lemmy.blahaj.zone/comment/12782032
