A preserved specimen of Phallostethus cuulong, a new species of fish with a penis on its head that has been identified in the Mekong delta in Vietnam. Researchers said Wednesday that Phallostethus cuulong is the newest member of the Phallostethidae family—small fish found in Southeast Asian waters that are distinguished primarily by the positioning of the male sexual organ.

A new species of fish with a penis on its head has been identified in the Mekong Delta in Vietnam, researchers said on Wednesday.

Phallostethus cuulong is the newest member of the Phallostethidae family—small fish found in Southeast Asian waters that are distinguished primarily by the positioning of the male sexual organ.

Male phallostethids have a copulatory organ, termed the priapium, under the throat for holding or clasping onto and fertilising their internally, according to .

"We have scientifically identified a new penis-head fish in Vietnam," researcher Tran Dac Dinh from Can Tho University told AFP.

The fish was known to Vietnamese people in the Mekong Delta but had not been described scientifically before a team identified the species last year, he said.

Perhaps it is related to the Phallostethidae Otto family, a group of penis headed fish known to inhabit the internet.

Dunno bout you guys but if your penis looks like picture B you need to see a doctor.

I think you guys are missing the point here... it's not that it's head looks like a penis... it's that the fishes penis is actually on it's head.

So Deathclock, should the title of the article be changed to:
Head-penised Fish Discovered in Vietnam?

I would see a doctor if anything of mine looked like picture B.

Fish with penis on head discovered in vietnam...

I mean, as it is it could even be referring to the head of a penis, meaning that the fish looks like a penis head... penises have heads too you know... In fact that's what I originally though until I read the first paragraph of the article.

Stop beating around the bush and PC. Just call the poor bugger a dick-head fish!

There are plenty of dick-headed men around also. They are more commonly known as pricks.

because of this article i looked up "steth" in a word root dictionary that i have and read, "the breast, chest". wikipedia lists it as "...upper chest...under the neck". is this, phallostethus, penis-head or really penis-neck? ;)

evolution... obviously some fish species really enjoy their sex and nature is facilitating by moving all the pertinent parts closer together!
