First footage of deep-sea anglerfish pair

October 16, 2019

This is a deep-sea anglerfish mating pair. These animals have rarely been observed in their natural habitat — hundreds to thousands of meters below the ocean’s surface. You’re watching one of the few known videos. And this one shows a sexually parasitic pair for the first time. That means during mating, the tiny male is attached to the female. He gets nutrients and she gets sperm. These specialized fish rarely survive the journey to the surface. Before now, most deep sea anglerfish studies used dead animals pulled up in nets and sometimes preserved in museums. In this case, the research team used a special submersible designed to capture images of creatures that live at these great depths. Like most other members of its order, this anglerfish is known for the bioluminescent, lure-like appendage that drifts in front of its mouth to attract prey. But this is the first time that what may be bioluminescence on the fish’s filaments has been documented. The swaying swarm of thin projections may act like a 3-d array of cat whiskers – sensing dangers and prey in the environment. There’s little to eat at this depth and it is very cold – leaving anglerfish with few calories to spare so it makes sense that as this video shows, the anglerfish female seems to use very little energy– slowly drifting and rolling through the water. But we don’t know much about their metabolism, the bacteria that supply their glow, or how the female’s body doesn’t reject the male’s. The special ship that took this video has been in operation since 2013 and there aren’t many like it in the world. So chances are, many anglerfish mysteries will stay that way for some time to come.

  1. My ex-wife hates cameras, how did you manage to get her on film?? She went from a 110 pound beauty to this 400 plus pound horror show in 10 years.

  2. The Male is giant and compare with her , if the woman didn’t say anything about her, I didn’t even know that her was under him , less mating.. She has bigs ?? to be with him , and the same time , she is very Lucky to have a big partner too protects her. Good on you girl .?????

  3. weve seen males attached to females before, the real amazing this is all the strands coming out of that species, truly amazing!

  4. I used to think that was the most unattractive looking scary fish I’d ever seen until now seeing it where it belong. It dose seem to have a beauty to it with all the laminated tentacles distracting you from their teeth! If males are that tiny, dose this mean that all large deep sea anglers we see or are on display are are females? Also if there isn’t much food at that depth, what do they eat and are those giant claws of teeth really necessary. Like fish that only eat tiny plankton don’t have the need for teeth. Anyway cool video. I learned about them in elementary and never forgot about that this one fish, guess it had an impression on me that’s why when ever I see one I know immediately what it is but this is the 1st time for me also seeing the long jellyfish like tentacles I had no idea it had. I just knew about the lil personal nite lite that extends right in front of their mouth and face. You would think an animal swimming buy would notice the giant sharp dagger teeth with a spot love on it but instead it seems the dangling lil light is a distraction from the teeth, mouth and fish itself. In reality I think in such pitch darkness all that would be seen by pray is just the lights and not the fish itself or it’s teeth. It’s just too dark and the tiny lights are just that and not enough to illuminate anything or give away the fish but then again I also though most animals at that depth were blind and mostly colorless because the lack of light forces them to evolve that way. Many curious questions.

  5. Having 2 wholly separate worlds on one planet is mighty cool. And it means there are tons of things to investigate in the liquid world. Why we don't commit more resources to it is beyond me. There are probably cures to some awful diseases to be found down there.

  6. Lol… Surprised they didn't call it a Trucker fish… Anyone else notice the similarities in pairing, to those seen at truck stops? Little skinny dude with a huge slow moving calorie efficient female in tow, or visa versa??

  7. Now that's love no matter how you look see female fish is so fat and male is just fit i guess ? just like me and my husband

  8. So you think with the advancements in dna engineering there will be a way to adapt human to not reject donated organs using angler fish dna?

  9. Took me years to erase the visual horror from the last video I saw of an angler fish…
    Thanks for the fresh nightmares YouTube!

  10. Yo!!! There’s just so much I don’t know, “Anglerfish”
    1) male is so small.
    2) exchange Sperm for Nutrients,
    3) Does not always survive the trip to the surface.

    Curious about No.3, do they get eaten by other alien fish, die of starvation and or temp change?? God so many questions…

    Great Video and informative, thanks and well done guys, ????✌?????

  11. Attached itself for life and gets nutrients while she gets sperm.

    Might as well rename it the "Jungle Fever Fish"

  12. The wonders of God's creation… "O Lord, how manifold are Your works! In wisdom You have made them all. The earth is full of Your possessions. This great and wide sea, in which are innumerable teeming things, living things both small and great" (Psalm 104:24-25). Thank you Lord for all the interesting creatures you have made.

  14. It's interesting to think that to the people born before the 20th century the bottom of the oceans was a deep and distant a mystery as Pluto, (now dubbed a "dwarf planet") which we now have detailed pictures of as opposed to a tiny smudge on the paper. We have come sooo far in such a relatively short span of time that it is truly mind expanding to consider.

  15. We can video these fish at these depths, finding a tiny tiny fish in pitch blackness, but we can't video a bigfoot. lol

  16. Dang that is scary seeing Hillary taking a bath as Bill injects his sperm in to that monster. I will have nightmares for weeks if not months to years even possibly decades..

  17. wow… what else can you say… Life is amazing.. I know I have seen some amazing things in my 67 years of it.. Carry on!

  18. Man… I have a feeling like they found some other species but they don't wanna show to us because of certain reasons ''from there up''..
