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.

The Shape of Life | Sponges: Time-lapse of Sponge Cells Recombining

This is a modal window.

Sponges are the only animals that if broken down to the level of their cells, can reassemble themselves. A sponge is passed through a sieve to break apart its cells. The cells recognize each other and reform into small new sponges.

    How many animals have we done this to?!

    So if you pushed two through the same sieve, would they recombine into their original selves or would they mix and be amalgamations of each other?

    If you cut off an arm of starfish, not only will the starfish grow that arm back, but another starfish will grow out of that severed arm.

    Aquatic life is weird, man.

    A Caterpillar changing to butterfly comes pretty close. The caterpillar essentially digests itself, turning into a goop along with a few special cells that guide the process of reconstruction back to a butterfly.

    That’s exactly the type of tenacity I would expect from Spongebob.

    I swear to god Jim you have to stop this! The cat died! The dog died! The ostrich isn’t going to reorganize itself either!

    so now we’re just grinding animals through sieves to see what happens??

    Can’t blame aliens for anally probing us now can we?

    **Zapp Brannigan**: Men, you’re lucky men. Soon you’ll all be fighting for your planet. Many of you will be dying for your planet. A few of you will be forced through a fine mesh screen for your planet. They’ll be the luckiest of all.
    **Bender**: Great. We’re gonna die.
    **Fry**: And this ham gum is all bones!

    What sick mind has done all the testing to come to this conclusion?

    “Test #3357 it appears as though the Orangutan (Pongo Pygmaeus) does _not_ reorganize itself when grinded to a fine sieve into salt water, thereby making the marine sponge the _only_ organism to exhibit such behaviour…”

    What kind of a psychopath discovered that?
