The anglerfish: The original approach to deep-sea fishing


Deep-sea anglerfish are strange and elusive
creatures that are very rarely observed in their natural habitat. Fewer than half a dozen
have ever been captured on film or video by deep-diving research vehicles. This little
angler, about 9 cm long, is named Melanocetus. It is also known as the Black Seadevil and
it lives in the deep dark waters of the Monterey Canyon. We believe that this is the first
video footage ever made of this species alive and at depth. Anglers have a remarkable apparatus on their
heads — a fishing pole with a luminous lure at the tip — which they use to attract their
prey. In the darkness of deep water they flash the light to attract prey and draw them near
the angler’s mouth. When a fish or a squid swims up, it is quickly inhaled by the angler’s
huge mouth and trapped by its long, sharp teeth. Given the shape of this angler’s body,
it is pretty clearly not designed for speed. Instead, these are ambush predators, lurking
in the darkness to grab an unwary meal. Another thing we can tell from the shape of
the body is that this is a female. In this species the males are much smaller and they
lack the fishing pole and lure. Males are ill-equipped for feeding and their sole responsibility
appears to be to find a female and mate with her as soon as possible. When we came upon this specimen, at a depth
of about 600 m, we noted that she has a broken tooth, you can see it on the left side of
her lower jaw. We have no idea whether it will be replaced by another after it falls
off. So far as we know, there is no tooth fairy in the deep ocean. You can see that
the eyes of this angler are quite small. In their dark habitat anglerfish rely more on
feeling the movements of other animals in the water around them than on vision. The
tiny pale dots you see along the sides of the fish and on its head are organs very sensitive
to the slightest movements and they function very effectively in the dark. The deep-sea is filled with surprises and
wonderful creatures. Humans have only just begun to explore this vast realm and we can
only imagine what discoveries are yet to be made.

  1. Its sad they don't show anything like this on TV.. Everything is about 'rare' footage, dramatic music, and 10 cutscenes in a minute ..

  2. this is the fisrt time I look at this fish
    thanks for share in you tube you make me know there are still many kind of fish in deep sea

  3. I think there's similar creatures camouflaged in the upper atmosphere. They wear clouds and at night dangle their lures too deep and we see them as UFO's.

  4. I think this fish looks majestic! Not like a monster. Besides the largest they ever grow is like slightly smaller than a basketball if anything, they're just minding their own business😊

  5. Cool animation….why are real footage of these fish seemingly impossible to find? They are that rare?

    Edit: holy shit, the comments….I've lost a brain cell….THIS IS NOT REAL FOOTAGE. If you had even 10 iq you could tell this. Like wtf? It's clearly a computer animation of sorts. This is stupid, waste of time, and enjoy the dislike.

  6. I'm by no means a marine biologist and the person narrating sounds like they know what they are talking about. However , he mentions in the lower right section of the mouth there appears to be a broken tooth dangling but from what I've learned about these fish what is dangling looks more like a male angler fish has attached himself as they do so for purpose of reproduction. I hope person who posted this video can enlighten me on why the biologists came to a different conclusion on what that is. I am very curious about it and hope to learn more about these fish

  7. jesus christ. they are so freaking scary and ugly looking. like actual demons. its a coincidence how they also happen to live in deep darkness and "underground" like hell.

  8. So bizarre looking to me that it actually doesn't even look real, compared to what you see of other ocean life. Unbelievable fascinating.

  9. It literally looks like a giant deformed head with a face that has an expression of extreme insomnia and terror. Like this – 😱
