Glass squid use an invisibility cloak to stay safe in the twilight zone

Glass squids (family Cranchiidae) live in the boundless waters of the twilight, or mesopelagic, zone. With no protective shell and nowhere to shelter, they need to get creative. Transparency is one way to thrive in a home with few places to hide.
Like other cephalopods, glass squids are covered in tiny pigment sacs called chromatophores. They often keep their chromatophores closed so their skin is basically see through. This invisibility cloak hides them from both predators and prey.
When the glass squid’s cover is blown, they expand their chromatophores to darken their appearance. Some may fill their body cavity with ink instead, presumably to blend into the darkness. And when danger still looms, a glass squid may ink into the water and jet away. A ghostly shroud of ink creates a distraction so the squid can escape.
But the future of midwater animals is in jeopardy. The deep seafloor holds buried treasure: nodules of precious minerals critical to modern technologies. Mining these metals will release plumes of wastewater that will cloud the ocean's twilight zone. Investigating how deep-sea animals sense their surroundings will help us predict how much harder mining will make their day-to-day lives.
We urgently need to identify the impacts deep-sea mining will have across all ocean habitats, from the midwater to the seafloor. Help protect the glass squid by sharing what you've learned. Together we can build a community of ocean champions!

It feel like a "fragile cosmic habitat" there down and we destroy it.... awwch, poor life forms!!!

Love that you guys are doing voice overs now. This would have been so annoying having text all over the screen drawing focus from these amazing creatures

Thanks again to all at MBARI and others who connect the dots. Unfortunately Man's greed knows no bounds but thankfully organisation's like yours are at least sure doing your best to keep us informed.

Hearing about the deep sea mining was devastating to me. It seemed so obvious when you have creatures literally living on those nodules its not ok to take them.

@zombieman333 4 ай бұрын

Especially that some from them exist of 100 of millions or even billions of years until today and all just to be extinct.... sometimes, the life isn't just fair!!!😓

Deep sea mining noise pollution effects on sea life have to be considered and evaluated too. Whales and other creatures already have difficulties with all the shipping and other human noises out in the ocean.

It would be super neat if humans have that ability to ink when they saw something dangerous coming around the corner. Can you imagine just ink the criminals and jet off lol.

@MBARI do y'all have a list of IDs for each squid that's shown here? might take a crack at it if not just for funsies...

@Sea_Leech 3 ай бұрын

Why do alot of glass squid have their tentacles high above their head, always vertical? Is it some form of mimicry, or does their feeding style rely on this? Im quite curious

I forgot about the glass squid. Btw a few great channels, deep sea oddities, natural world films and EVnautilus

0:39 wait this squid can be up to TWO METRES long?? is it supposed to be 10-20cm and NOT 200cm?

@Radiata_Lionfish 11 ай бұрын

There are some species that are indeed two meters long mantle size, Megalocranchia and Mesonychoteuthis do reach sizes similar to that, the latter being the colossal squid and the largest squid that we know of.

It's such a shame, but I think the biggest cheer will go up by every living animal the day humans go extinct.

@zombieman333 4 ай бұрын

Isn't necessary that we to go extinct.... stop being against at your race, the humanity like every other animal is important for ecosystem.... we can destroy "the nature and planet" but we can also to protect the life forms on earth.... not all people are same, you like "regular human" can decide to save the world but in the same time you don't.... this mortal life is a "play game" with cossecinces.... all what we do, well be giving back to us in exactly the same way we do.... trying to destroy nature, the nature will fight back.... trying to destroy the life, the life still will find a way, so this is how the life and things actually work!!!

@stocktonjoans 11 ай бұрын

is that the reason though? how many predators at that depth actually use sight as the primary hunting sense? it's not like there's much light down there, one would assume that other senses are used to compensate, plus some sea creatures can detect electric impulses in other's and use that to hunt with.

Deep-sea animals use a variety of sense to navigate life in the deep. While there's no sunlight in the deep sea, about three-quarters of life in the water column can produce their own light, known as bioluminescence. The MBARI team is working to decipher the secret language of light in the ocean’s depth: www.mbari.org/know-your-ocean/bioluminescence/

In addition to clogging the animals’ filtering mechanisms and adding non-nutritious or toxic material to these animals’ diets, the sediment would absorb the blue-green light that glowing deep-sea animals use to attract prey, search for food, and find mates. The mining process is also extraordinarily noisy. There are many ways mining may impact life in the deep. We must learn more about the impacts before this practice becomes common.
