Deep-sea sighting: The strawberry squid’s mismatched eyes are the perfect pair

- During a recent deep-sea dive, our team came across one of the most remarkable residents of the ocean’s twilight zone: the strawberry squid (Histioteuthis heteropsis). MBARI’s remotely operated vehicle (ROV) Doc Ricketts spotted this crimson cephalopod 725 meters (2,378 feet) deep in Monterey Canyon. The stunning ultra high-definition resolution 4K video from the ROV Doc Ricketts allows researchers to examine deep-sea denizens in astonishing detail.
The strawberry squid has one big eye and one small eye. Together, this unlikely pair helps the squid hunt for food in the ocean’s twilight zone. The big left eye looks upward to spot shadows cast by prey in the dimly lit waters above. The eye’s tubular shape helps collect as much downwelling light as possible. Often, this eye has a yellow lens to see through the luminescent camouflage of its prey. The squid’s right eye is small and looks downward. This eye searches for flashes of bioluminescence produced by prey or predators lurking in the darker waters below. This squid is sometimes called the cockeyed squid for the remarkable difference in size between the two eyes.

The large eye, located on the left side of the head, is used to look up and detect shadows cast by prey in dark waters. The tubular shape of this eye helps it capture as much light as possible, and often the eye has a yellow lens that allows it to see through the luminescent camouflage of its prey.
The smaller, right eye is turned downward and looks for any flash of bioluminescence that its prey or other predators might produce.
Accidentally designed by a random god of chaos🙄
'Special Ops' Squid with the night vision gear 😁
Right! We studied them and invented it from there beautiful eyes!
Imagine that…
“It is the same below, as it is above”
Graceful, unique and cute as can be. Thank-you you all so much for sharing the wonders of the oceans. ✌😎🤘
Hi you
I'm so so sooo deeply in love with strawberry squid thank you for putting this beautiful footage as it's own video!
Symmetry is not everything! I am so interested in this squid. I hope we can learn from it!
@@KenericTheGeneric True.
@@KenericTheGeneric That is not true, the eyes are the asymmetrical feature, while the rest of it's body and organs are "normal".
It still had symmetry
@@KenericTheGeneric It has bilateral symmetry
OMG!!
I wish I could make the letters bigger to tell you how excited
I am!!!!
YEAH!! Now this is one of my favorites in
ALL THE SEAS!!
Hey there!
Monterey Bay. Research Institute TEAM!
Cheers!!
To the best of the humans on the planet!
Wow. Incredibly detailed images of an amazing squid.
Watching it curled up made me realize they must be related to the nautilus
YEAH..I think you’re brilliant, I like your brain! Nice!
my grandpa is like that
I wish I could pick you & your grandpa up and take ya down to the aquarium today!
It is so beautiful!
Maybe you can take him?
You’re sweet…
Amazing!!!
Love these deep dives
so adorable
So grateful to always watch these!
Cannot wait to see Into the Deep exhibit in the near future!
Thank You, MBARI👍🙂🇨🇿
Holy moly, I didn't realize that they had assymetrical eyes! What a wonderful little fella!
BEAUTY IS IN THE EYE OF THE BEHOLDER
4k footage! This is awsome.
Regard the magnificence that is Squid!
This is absolutely everything.
What a beautiful creature.
This is what strawberries evolved from
Criatura formidável, magnífica.
Esse olho enorme deve ser capaz de ver tudo nas profundezas, uma obra prima da seleção natural.
Wow, very cool!
Qué bonitas tomas. 😍💚💐
Amazing!!!!!!!!!!
Beautiful.
Cool! Based on the little I know about nature it’s probably the result of a symbiotic relationship with a parasite 😂
What a strange squid. Why does it have such strange eyes?
The eyes of H. heteropsis are dimorphic both in size and in lens pigmentation for specialized vision in the ocean’s mesopelagic zone (200-1000 meters below the ocean surface). The different properties of the squid’s eyes allow it to see a variety of different light sources present in its habitat, primarily downwelling sunlight and bioluminescence. H. heteropsis hatchlings are born with identical eyes of the same size and pigmentation. As they develop, the left eye becomes larger and more pigmented. By adulthood, the left eye can grow to be over twice the size of the right eye and has a distinct yellow lens pigmentation. In a 2017 study conducted by Kate Thomas, Bruce Robinson, and Sönke Johnsen, it was found that the large left yellow eye is oriented upwards for viewing objects in dim sunlight and the smaller right blue eye is oriented downwards for viewing bioluminescence. While the larger eye can detect bioluminescence fairly well, the smaller eye struggles to view black objects in dim light. (Wikipedia)

@@KenericTheGeneric using fancy/complicated words are important to be specific in describing something technically, but it has the side effect of being hard to understand for a lay person. It seems unnecessary, but it’s important! That’s why good science communication is so crucial.
Beautiful ❤️
this is the first MBARI creature that looks potentially delicious
It lives up to its name.
Surreal, like another planet
They sure picked the right name for that squid for sure
Good
I always wonder if it isn't harmful for those eyes, which are made for the darkest darkness and have no eyelids to protect them from light, to shine a stadium level light directly in there.
💚
are the eyes always asymmetric BTW?
Maşallah ❤
This thing is just 13 cm long! Or 5 inches if we use silly measurement units.
Luminescent camouflage sounds like it’d be an oxymoron, but I’m guessing in this case it has to do with masking the shadow it would otherwise cast without it. It’s brilliant what evolution comes up with when animals are put in the most alien parts of the planet.
😮😮😮😮😮
what's wrong with it's eye ?
pq parece um modelo 3D???
i love the high quality of this video, it almost feels as if i can touch this squid (i wouldnt do it if it said no)
i don't have a degree or anything. I'm pretty sure it's the bulging 1 i mean there's gotta be millions of ocean parasites that will never know about
3.5 inches long; sigh of relief.
That's what she said.
I hope garnet rogers got song fee.
Would love to kiss that squid
Is this fake, who would even get this close?!, it doesn't even look like water..if anything it looks like a photo shopped stary night
o . O
lookin yummy
This is what the giant one says about you when you’re diving!
Just by chance not to be Debbie downer, if you happen to harvest something like this, please do consider they’re so rare, and they can make so many more babies out in the ocean if you don’t steal it
yummy
Praise the Lord God ; Jesus Christ of Nazareth 😇
