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."

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.
Greenland Shark.
Living that deep the shark must be under a lot of pressure to find food.
Your neighbor has a robust appearance.
har har.

That is a tooth from a Megladon Charcadon Shark. Probably collected on the Maryland shores. I have one. Unfortunately I do not have the “frail old lady” holding the tooth.
I’ve been studying that pic very closely for a while but I haven’t seen a shark’s tooth yet. Are you sure there is one?
Thanks. I figured that's what it was.
Re-read that little article. I don't know that that assumption can be made. Its a pretty good rule of thumb that if an animal is found to be in an area where it doesn't normally belong and its acting in a manner that is unusual then there are problems in the environment back "home", they have a special purpose for their travel, or the animal is sick. Im not claiming to know why this shark was doing this but more likely than not there is a problem with the food supply, its engaging in some sort of mating/mate finding behavior, or its dying from something. I seriously doubt that the tagging has much to do with anything related to its subsequent behavior.
Yes, of course there is! Are you blind??
:)
“It’s so big!”
I'm guessing they have experience with other sharks and would know if/how tagging affects sharks in general.
“Oh look! Shiny jewelry!! I'm going to leave the reef and swim all over so EVERYONE can see it!”
Yeah, she's a sweet old gal. Last night, after a slow walk around the block and a bowl of soup with unsalted crackers at the local diner, I took her to the big bingo tournament!
Lol!
And who saw it 200 million years ago?
