A new species of fish with a penis on its head has been discovered in Vietnam. But it's not what you're picturing — actually it's probably worse. This penis includes a rod and a jagged hook used for grabbing the female during sex.
The fish, Phallostethus cuulong, was discovered by researchers in Vietnam's Mekong Delta. It is the newest member of the Phallostethidae family, a group of fish with small, skinny, nearly transparent bodies that live in Southeast Asia, and which are distinguished by the location of their sex organs.
The more technical name for the male fish's penis is the priapium, a complex, muscular organ that looks like it's attached to the fish's chin. The priapium includes the urogential opening and the anus, as well as a bony rod and a sawlike hook, used to clutch on to the female during mating, the researchers said. The female fish's genital opening is also located at her throat.
