8 Incredible Deep Sea Oddities!

8 Incredible Deep Sea Oddities!


We know more about some other planets than
the deep sea, but scientists at places like the Monterey Bay Aquarium Research Institute
are sending eyes in to the darkness in the form of remotely operated submersibles beaming
back some amazingly odd images. The green blobs inside the barreleye fish’s
transparent skull are actually its eyes or two tiny spacemen! Those tubular eyes rotate
90 degrees upward to look for the silhouettes of prey and point forward for feeding. Those
two spots near its mouth are actually scent receptors similar to our nostrils. Just a handful of anglerfish have ever been
captured on video. They fish for prey using a glowing lure filled with luminescent symbiotic
bacteria. The pale dots on their body are pressure sensors used to sense movement in
the pitch darkness. And those teeth can probably tell you what happens next. Little is known about these deep-sea comb
jellies. Their iridescence is only visible under these bright lights. It comes from tiny
pulsing hair like cilia that propel it through the water. These jellies are nearly invisible
in the dark depths where they live though. Since nearly all red light has been filtered
out by the water. Humboldt squid can measure up to six feet
in length and a hundred pounds. They hunt in massive schools flashing red and white
with color changing cells, capturing fish in their barbed tentacles and shredding them
with their sharp beak. But even these speedy predators can get startled, squirting ink
as a diversion to escape. The vampire squid is not a squid at all. And
it is also not a vampire. They eat mostly marine snow – a mixture of dead bodies, poop
and gelatinous stuff that rains down from the shallow ocean above. Great now I’ve lost
my appetite. The viperfish’s teeth are so big that they
can’t even fit in its mouth, which gives it a pretty ferocious and also pretty ridiculous
appearance. But who knows. Maybe they are just smiling. This next…um…this…uh…is apparently
a squid. Or I don’t…let’s move on. Since longer wavelengths of light are filtered
out by the water, most creatures in the deep sea have evolved to not see red. Except the
loosejaw. Which uses the glowing patches beneath its eyes like their very own night vision
goggles. Earth’s oceans are kind of like the internet.
The deeper you go, the weirder it gets. Stay curious.

  1. You should make a video on H.P Lovecraft and the history of deep sea exploration.

    H.P Lovecraft hated seafood, and by extension used the lack of knowledge on the deep sea as a narrative tool for horror. It wouldn't be until 1960 that scientists would admit that there was life found in the deep sea, before then it was believed that it would be impossible for life to exist at such a depth do to the lack of sunlit. Not only did they find life, but they found it thriving.

    Also I love H.P Lovecraft and Call of Cthulhu…

  2. This is definitely the best of the series yet. Deep Sea fish are fascinating, it's a shame we may never know as much about them as we'd like.

  3. You know there are some unbelievably gigantic things down there. The ocean gives me nightmares despite it's vast and interesting beauty.

  4. All light but red ruins night vision, so is there any night vision that deep in the sea? If not how can they be caught on film in such dark areas?

  5. We have so much diversity here at home, image the absurd otherworldly-looking creatures we may find in other planets. Awesome!

  6. When i see this, i start thinking about the ocean under the ice on Europa…i wanna see whats there. :p

  7. Sometimes I do wonder if scientist make up half these deep sea creatures, super surreal.
    "Hey guys, I know we need some cash, let's pretend to find a fish with its eyes I it's skull and make the skull transparent…
    You idiot you've drawn real eyes on its face, don't worry we'll say their nostrils….
    Get ready for that deep sea diving grant, papa can do with a new Ferrari'

  8. I'm going to ask the obvious here; how the hell is the vampire squid NOT a squid, but that one thing is? That's like Alolan Exeggcute being a dragon type and Charazard isn't!

  9. the vampire squid looks like something you'd find at the bottom of lake cocytus.
    could it be these species are in fact living fossils? after all, most of them are mostly found in the depths of the ocean.

  10. The loose jaw and Taonius were my favourites because I have never heard of them before? What was/were yours?

  11. Don't dumb down the facts or skip over segments to " not appear intimidating", it's insulting to those who enjoy learning.

  12. Comparing these research activities to aerospace research is not a good thing to do.

    As a small example; imagine if these marine biologists had to have a precise and testable hypothesis every time they left the lab? Naw, they just get on a boat every day and go looking for whatever they can find. Granted that is likely the best way to do this foundational biological research, but what if space exploration needed so little justification? You can't justify a billion dollar project that's going to take ten years without some hard questions to answer.

    This is less like research and more like taking a census. It's important work but it's not very impressive.

  13. The bloody belly comb jelly is so pretty🤩 i'd probably die if I was a sea creature trying to get closer to one of these because of its beauty😅
