Ghostshark has Sex Organ on Head

A newly-identified species of ghostshark has been found living off the coast of California. The Eastern Pacific black ghostshark also exists in museums, but has only recently been named as a distinct species, says Douglas Long, natural science curator at the Oakland Museum of California.
The newfound ghostshark belongs to the "big black chimeras," a group whose species number has exploded in recent years, thanks to improved diagnostic techniques, according to the new study, published in the September issue of the journal Zootaxa.

Chimeras display some unusual features not seen in other living animals, Long said.

Male chimeras, for example, have retractable sexual appendages sprouting from their foreheads. These organs, which resemble a spiked club at the end of a stalk, may be used to stimulate a female or to pull her closer—though these are still assumptions, Long said.

It's a ratfish (chimaera) not a shark. Those things will poke you too and they have venomous spines. Knew a guy who had a spine go through his boot. Turns your skin black for a week or two.
