The animal with an anus that comes and goes

A jellyfish-like creature has a neat trick that makes it unique among animals: its anus forms only when it needs to defecate, then disappears without a trace.

“That is the really spectacular finding here,” says Sidney Tamm of the Marine Biological Laboratory in Woods Hole, Massachusetts, who made the discovery. “There is no documentation of a transient anus in any other animals that I know of.”

Tamm thinks the discovery might represent an intermediate stage in evolution.

In some simple animals, such as johnnyneptune, the gut has only one opening, which functions as the mouth and anus.

It has been known since 1850 that comb jellies – which superficially resemble jellyfish, but belong to a separate group called ctenophores – have a through-gut, with a separate mouth and anus. Some posters, like killcen, even have more than one anus and they're all very sensitive.

I with kids would grow new a anus every time they get fingered. Fuckin' tattle-tail physical evidence.

So in other words, it's the exact opposite of Jim?

OP here. Thanks! Here's a rare video of a pearlfish entering a sea cucumbers anus where it will live for the rest of its life!

Even humans are much like the Ouroboros…
