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.
