Researchers have captured the mysterious bluntnose sixgill shark on film, a creature [species] that has been on Earth since before the dinosaurs.
Described as "perfectly efficient" by the team from OceanX and Florida State University, the bluntnose sixgill shark is largely still an unknown to researchers, despite having been on the planet for nearly 200 million years.
Occasionally, they come to the shallow waters, rising from depths as far as 8,200 feet, according to Science Alert, where they arrive under the blanket of the night sky to feed.
In capturing the mysterious bluntnose sixgill on film in the Bahamas, the researchers also managed to achieve history.
They were able to tag the creature from a submersible vessel, the first time that feat has been achieved.
"Because bluntnose sixgills are a deep sea species, it’s hard on them physiologically to be tagged in this way," the researchers wrote in a blog post, describing the achievement.
"In their typical life cycle, they won’t experience daylight, and very rarely will they feel the low pressure, warmer temperatures of surface waters.
Typically, the data obtained after surface tagging of a six gill is believed to be skewed, as the shark does not return to its natural behaviors for some time after the tagging."

Would have been nice if you included a picture of the specimen...
There is a gap in your tooth less story but, do keep me a breast if you find further evidence...
That’s what she said!
Them some fine lookin’ teeth.
This is one of those trick photos, where if you stare it long enough, a shark tooth comes into view!
That shark doesn’t look a day over 10 million.
Emma biggins finds shark tooth.
I suppose a fish that goes back “nearly 200 million years” is fairly impressive, in a sense, but, then again, I can drive a few miles and catch (from strong populations) fish that go back over 150 million years: Gar. More rarely, bowfins. Both inhabit MANY waterbodies. These sharks are a lot rarer, apparently... Do they taste better? :-)
Send the poor frail thing over to my place. After I get a look at the tooth I’ll help her across the street or something.
“Anyway, she was so nice that she brought it over and we spent the entire night talking about prehistoric sharks and their evolutionary histories. I took the following photo of her with the tooth first thing in the morning. Poor woman is so frail she could barely lift the thing.”
Bless her heart! That was nice of you to keep her company, I’m sure she doesn’t get many visitors.
Stop exploiting that tooth!
*ping*
Tooth? What tooth?
In a sense. fairly impressive?? We're talking 200 HUNDRED THOUSAND TIMES A THOUSAND, years!
In any case, the article is wrong in that this shark species appeared before the dinosaurs, as dinosaurs first appeared somewhere around 225-235 million years ago.
Re: We’re talking 200 HUNDRED THOUSAND TIMES A THOUSAND, years!
*TWO* HUNDRED THOUSAND...! :)
You’ll need a bigger boat for those!
They have found moose, elk and caribou in the guts of Greenland sharks caught deep, so surface behaviour may not be as uncommon as thought.
Right. And you are correct about the sharks’ vs. dinos’ timeline.
But I’m still almost equally impressed that I can drive to any number of area waterbodies and catch fish that go back 150 million years, and they (esp. the longnose gar) practically overrun certain of these lakes. We’d eat ‘em (gar - not bad at all if prepared correctly), but, to clean ‘em practically requires aviation snips (GOOD ones), strong hands, determination, and maybe a saber saw...
Nice specimen!
