Marine Sponge Reorganizes Itself

TIL If you grind a marine sponge through a sieve into salt water, it'll reorganize itself back into a sponge. It's the only animal that we know of that can do that. How many animals have we done this to?!

A screenshot shows a fact about marine sponges being ground through a sieve into salt water and reorganizing themselves, followed by a sarcastic question about how many animals humans have subjected to the same process. The joke comes from treating an absurd and disturbing experiment as if it were a normal scientific comparison.
