Thank you. But are jellyfish really not that far off. Looks like a pretty huge step to me. Jellyfish look complex enough to not just magically reassemble if we grind them through a sieve.
I personally (but I’m not a biologists 🤣) definitely would consider a jellyfish an animal because different cells (at least ot very much looks like that) have different functions and thus throwing it in the meat grinder (even if individual cells are not damaged) I can’t imagine how ot could reassemble itself.
But a sponge seems so homogeneous it (I guess) almost doesn’t matter what goes where and that’s why it can reassemble. That why (I personally) wouldn’t think of that as an animal.
Are there other things that are technically animals that are that homogeneous?

Little pieces of a jellyfish can become new jellyfish. They can reproduce sexually or asexually. The Immortal Jellyfish is even weirder. They are some of the simplest multicellular animals after sponge and coral.
