How many animals have we ground up and put through a sieve into salt water to be this confident about it being the only animal that can do this? I need sources.
I think there’s nematodes that we’ve blended up before, but instead you get a bunch of nematodes instead of just one.
what’s a nematode?
basically tiny worms, often shorter than a few milimeters. it’s the name for a whole group of different species, so some are microscopic while some can be several cm long
sounds yuckyy I hate insects and worms
