Fluorescence in the deep-sea squid Histioteuthis: The case of the green-eyed squid

Scientists at MBARI recently deployed blue light-emitting diodes (LEDs) on our remotely operated submersibles to observe fluorescence in deep-sea animals and investigate the ecological roles of light in the deep sea. When we shined blue LEDs on the strawberry squid, Histioteuthis, we were surprised by an impressive light show. This squid has one normal-sized eye, and one extraordinarily large eye, which was brightly fluorescent, indicating the presence of a blue-absorbing fluorescent pigment. The fluorescent pigment most likely aids in capturing prey by breaking their camouflage. Many organisms have fluorescent structures, but we are still exploring what the natural functions of these fluorescent pigments are.

I wish these videos were a bit longer. I could watch for hours.

[@nnananahh]

Same!

[@mozvidz]

You'll be surprised there are many other thousands of similar content on RUclips, but the logarithms will never bring them to your suggestions. Just type the search terms you wish to see, and you will get unlimited content.

[@memes.tofollow]

No. Keep it short

[@gorannovaks]

Fantastic job, catch the 700-th like! :)

[@TheDoveking]

I really don't understand why this channel does not have more views and subs. It's fascinating and showing us (almost every time) new creatures on our planet!
People misuse and bastardize this word but this channel is genuinely amazing.
Along with awe inspiring. looking forward for more ^_^

[@--Paws--]

For some reason I became unsubscribed; others may have been affected in one way or another. Currently, as of this moment, RUclips may have once again changed its format.
Many have different interests - cat videos for some then there are videos like this.

Steve Haddock? Please tell me you're a captain.

[@WilliamBlarBlar]

This is one of the few educational channels that doesn't go overboard with sound effects, generalizations, or jokes and gimmicks. I really appreciate the straightforward information.

[@umageddon]

A squid with 2 different eye types? Seriously can stuff get any weirder?

[@johnm2012]

Oh yes, search for barrel eye fish.

[@umageddon]

johnm2012 they show it in this video.

[@KavenLeandro]

A guy who would eat it

[@CasparAbelmann]

Would a blacklight give the same effect?

[@MBARIvideo]

Caspar Abelmann It *would* give the same effect. A blacklight is just a shorter
wavelength version of the blue light, but we use blue because it travels
farther underwater.

Wait...my lenses fluoresce under UV? Is this why UV lights look blurry?

[@annaannarasumanara4444]

Ahh, I want so badly to work in places like this in the future, but now I'm just a student. Hope I'll be a good marine biologist and invertebrate zoologist :^)

[@gustavoguimaraes5620]

Awesome !!!!!!
What kind of jellyfish is in 01:35 ?

[@kyraschlining4562]

gustavo guimaraes The jelly that cruises through the background is a species of Aegina. Glad you enjoyed the video.

[@romanramos1976]

That is a squid

[@creekandseminole]

It's always a treat when new videos get posted from MBARI. I love deep sea life. It's so mysterious and "alien".

Found the octopus which inspired the last gen BMW 1000RR

[@gingergiggles]

Strawberry squid. I'm so happy such a thing exists :D

[@rartyblart]

Thanks -- I'm now a big fan of the strawberry squid.

[@31aicirtl]

Hmmm now I crave strawberries 🍓

Hi, I work for InGen.
I would like to incorporate your research into our dinosaur theme park project.

Thanks Steve Haddock : )

This probably what dream stans expected when they voted glow squid

[@tonybaloney8401]

im in love with this!

[@sur3real685]

For any wondering this squid is called the strawberry Squid.

[@Life_Is_Science]

[@flednanders7556]

I refuse to call this squid anything other than Ruckuteuthis.

[@afinendale]

It's like an underwater arms race. Amazing.

[@iilee408]

Fascinating. This means we can see certain wavelengths of light that we arent even aware of. And it must serve some purpose or we wouldnt have it

[@JustJohn505]

Aliens do live among us even if we don't see them because they are to deep into the ocean

[@Handl949]

these videos and narrations are amazing.. wish there are more

Absolutely fascinating!!
