    There is no permanent connection between the gut and the rear of the body. Instead, as waste accumulates, part of the gut starts to balloon out until it touches the outer layer, or epidermis. The gut then fuses with the epidermis, forming an anal opening. Once excretion is complete, the process is reversed and the anus vanishes.

    It has a vanishing, temporary invisible anus. WTF

    In 2024 it was described to possess the ability be biological immortal by undergoing reverse development after the onset of sexual reproduction from mature lobate to early cydippid

    And it’s immortal.

    The horse rectum and anus are a marvel of engineering. Together, they’re capable of expelling waste, segmenting waste, and cleaning themselves, with one contraction performed by a single muscle.

    As the sphincter contracts, it pushes out the waste, while also tightening to divide the waste into precisely segmented portions. If you weigh the individual pieces of waste, they weigh the same, within only a half ounce or so of each other.

    After the waste is expelled, before the sphincter relaxes, it squeezes the rectum in the direction of the anus, effectively cleaning the rectum of any remaining waste.

    This design has been replicated mechanically and applied to countless manufacring processes. Just about any time some amount of fluid needs to be precisely portioned out on an assembly line, it uses a device that was designed to be basically a mechanical version of a horse’s asshole because it does such a good job of dispensing consistent quantities while minimizing waste, requiring very little maintenance and upkeep, and being very simple to build.

      thats fascinating. i always wondered how they got away with having their vagina and rectum in the same hole. it sounds like it would cause all kinds of problems, yet horses exist.

      Do your kids ever fight about who’s getting more food?

      Not any more!

      Here kids, meet Buddy! A huge help on the farm and in the kitchen!

      Note: horse enema syringe sold separately. Minor changes to food flavour may be experienced, this is normal and not a cause for concern. Avoid dispensing of spicy foods as it might cause explosive discharge and/or being kicked.

      Huh. So I heard about that chemical that was basically supersaturated query oxygen or something, that you could put in a drowning person’s lungs to at least let them breathe while their lungs are full of fluid. Are they suggesting we boof it?

      Animals like pigs, rodents, turtles, and some fish are known to be capable of butt-chugging oxygen when the need arises.

      I want to see “butt-chugging” in an accepted scientific article now.

      The experiments only injected a non-oxygenated fluid into the participants rectums, just to see if it was safe to do, which it was. Next step will be to actually test how well your butt can breathe the oxyneated gel.

      Anyways, if this works athletes would be able to cheat on a whole new level. Would be awesome if you could inject it into your butt before freediving tho.

    So if they each injure their asshole (hey, it happens 🤷‍♀️) do they fuse their butts together?
