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.
That's hott. Two pearlfish assfucking inside of a sea-cucumber.

Are you saying the johnnyneptune can eat shit, but that the killcen's shit eats him?

So it's like pornhub but it's a fish?
Luis Flores
Exactly.

I prefer animals with an anus exclusively used for defecation, like cows and horses. This way when the animal is not defecating I could have anal sex with it. They do not mind, but the animals with an anus for a mouth always have a problem swallowing my sexual practices.

transient anus requires a transient e r e c t i o n

Who? I've never heard of either one of those faggots, you must have this place confused with reddit.
Jason Turner
In my defense… This place seems a lot like Reddit lately. I may be somewhat confused, but still not nearly as much as this place is. It doesn't know its mouth from its anus half the time!
