Watch: Mysterious spook shark prisoner on camera for a initial time

Like a Greek imaginary namesake, a chimaera — or “ghost shark” — is a mysterious, frequency seen quadruped with a patchwork of bizarre features.

Dwelling in a inlet of a ocean, a eyes are dark and clearly dead. Where teeth should be, a spook shark uses tooth plates instead to grub food.

Their heads are lined with cryptic dots, like a vestige scars of ancient stitches. Male chimaeras have retractable sex viscera — on their foreheads.

Its other nicknames — ratfish, rabbitfish, spookfish — spirit during how weird chimaeras are in appearance.

And now, scientists trust they have prisoner on video a class of spook shark that had never before been filmed live: a pointy-nosed blue chimaera.

The tangible video was taken in 2009 though was usually recently expelled by the Monterey Bay Aquarium Research Institute, along with a paper by researcher Lonny Lundsten and his colleagues during a institute.

Six years ago, researchers from a nonprofit sent an ROV, or remotely operated vehicle, on several dives off a waters of executive California and Hawaii.

The ROVs prisoner footage from inlet of adult to 6,700 feet. What they returned with astounded researchers: On film was what seemed to be a class of spook shark formerly usually held in a southwestern Pacific Ocean.

According to his paper, Lundsten consulted with 3 chimaera experts who watched a video from a diving expeditions. All believed a fish was, in fact, a pointy-nosed blue chimaera.

Still, Lundsten and others from a Monterey Bay Aquarium hospital can’t be 100 percent certain that a fish prisoner on video is a pointy-nosed blue chimaera, notwithstanding their identical earthy characteristics. Because of that, a paper refers to a fish they available as Hydrolagus cf. trolli, rather than a systematic name, Hydrolagus trolli.

To be positively sure, researchers would have to constraint a spook shark and move it behind to a surface, the hospital said.

“This is most easier pronounced than done, since these fish are generally too large, fast, and flexible to be caught,” a hospital notes. “If and when a researchers can get their hands on one of these fish, they will be means to make minute measurements of a fins and other physique tools and perform DNA research on a tissue.”

Doing so would possibly concede them to mislay a “cf.” from a class outline — or lead to maybe an even some-more sparkling alternative: that they detected a new class of spook shark.

“If these animals spin out to be a same class as a spook sharks recently identified off California, it will be serve justification that, like many deep-sea animals, a pointy-nosed blue chimaera can unequivocally get around,” a hospital said.

The pointy-nosed blue chimaera was initial detected by researcher Dominique Didier Dagit in 2002, in a low waters around Australia, New Zealand and New Caledonia.

Dagit, afterwards an partner curator of ichthyology during a Academy of Natural Sciences in Philadelphia, told a Associated Press in 2002 that she named her find Hydrolagus trolli after Alaskan artist Ray Troll since they common a adore for ratfish.

”It’s kind of good to be means to name a class for someone,” Dagit told a AP. ”I thought, ‘Here’s my possibility to name a fish for someone who’s unequivocally interested.’ … It kind of looks like him, [but with] reduction facial hair.”
