Actual explanation: these squid are transparent normally, but can turn on a dark pigmentation when that is a more effective camouflage. Being transparent works quite well most of the time, but if the predator has its own light source (as several deep-sea predators do) then their transparent state becomes a problem, because it's relatively reflective compared to the water around them. In this situation, turning on the dark pigment helps them blend in with the dark water better.

Fixed link. PDF

Edit: interestingly I think your link as formatted will work on the website but not in Sync. Can anyone else report if this is the same for other apps?

OP's link for posterity:

Android.

Connect app: a blank page both times

Mobile FF: a pdf both times

Seems like my app just can't render files.

[-] can@sh.itjust.works 3 points 2 months ago* (last edited 2 months ago)

I'm confident Connect would support escape characters so maybe I just need more.

Edit: or maybe less, try this one [test link](https://www.cell.com/current-biology/pdf/S0960-9822(11)01138-9.pdf). PDF

An error on the site itself, hm.

I think it's not it's fault but of the webview (?) app it borrows from the system.

[-] can@sh.itjust.works 2 points 2 months ago* (last edited 2 months ago)

Bring it to the dev's attention? They seemed pretty on top of things when I used that app.

[-] Skua@kbin.social 2 points 2 months ago

Huh, not sure what's going on there. It looks fine on my instance obviously, but it seems fine on yours and the post's in the browser at least. Then again kbin seems to be particularly janky with links in particular. Thanks for making a version everyone can see

[-] can@sh.itjust.works 2 points 2 months ago

It has to do with the fact that there's parenthesis in the URL but parenthesis are also part of the link markup. So unless something accounts for that then it will cut the url off prematurely. I think maybe the default Lemmy ui takes care of that automatically.

[-] hessenjunge@discuss.tchncs.de 2 points 2 months ago

Voyager/iOS has no issue with any of the link formats.

If squids can turn transparent, why do they bother with all the colors and camouflage? Maybe it's just because they like to show off

[-] FooBarrington@lemmy.world 119 points 2 months ago

Transparent can still be more visible than good camouflage. Just look at how well they can imitate rocks and similar debris: https://youtu.be/q8xJ13pAZNw

[-] AeroLemming@lemm.ee 42 points 2 months ago

Holy hell. So I guess cloaking technology already exists, it's just that the octopuses got to it first.

[-] nilloc@discuss.tchncs.de 23 points 2 months ago

I wonder how much energy it takes to transform, or hold patterns like that.

Also it’s a bummer they’re lives are so short. We need some more smart octopi in our world.

[-] Sylvartas@lemmy.world 14 points 2 months ago

I'm convinced that if octopi had significantly longer lifespans, they would be the ones dominating this planet, and you can't convince me otherwise

[-] TachyonTele@lemm.ee 9 points 2 months ago

Imagine how cool their gamepads would be

[-] octopus_ink@lemmy.ml 63 points 2 months ago

Maybe transparent is maximum effort? (I have no idea, I'm just guessing.)

[-] imaqtpie@sh.itjust.works 105 points 2 months ago

Suspicious username...

[-] octopus_ink@lemmy.ml 43 points 2 months ago

😆

With absolute sincerity my username is totally random. I wanted to pick something with zero connotations/implications (as far as I know) and that I'd not used previously.

[-] BalooWasWahoo@links.hackliberty.org 15 points 2 months ago

zero connotations/implications

I know that octopus ink makes a decent base for pasta sauce, and gets your teeth quite colorful. I think you're implying you want to be squeezed with some butter and get all over someone's tongue and molars... You're so dirty.

[-] MalReynolds@slrpnk.net 4 points 2 months ago

Wow, escalation.

[-] Damage@feddit.it 4 points 2 months ago

What? It's a very offensive racial slur!

[-] octopus_ink@lemmy.ml 5 points 2 months ago

LOL! (I assume)

[-] fossilesque@mander.xyz 32 points 2 months ago* (last edited 2 months ago)

Fixed:

[-] imaqtpie@sh.itjust.works 2 points 2 months ago

Lol! Nice one

[-] moody@lemmings.world 13 points 2 months ago

They typically can't. Scientists genetically engineered some squids to have transparent skin, and since their innards and blood are basically already transparent, this is the result.

I don't know if these genetically modified squids can still change colors though.

[-] RealFknNito@lemmy.world 54 points 2 months ago

Interesting. Now, who do we thank for this post? checks notes

[-] fossilesque@mander.xyz 19 points 2 months ago

The hero we deserve.

[-] Buddahriffic@lemmy.world 15 points 2 months ago

I had a cat a while back that was in heat when I first got her. She spent pretty much that whole week running from the front to the back of the apartment and back to the front, looking for a male. She was a poor horny cat.

[-] Please_Do_Not@lemm.ee 44 points 2 months ago

What about their blood and organs and anything it had recently eaten? How does 100% of it turn transparent

[-] MelastSB@sh.itjust.works 51 points 2 months ago

Nanomachines, son

[-] gregorum@lemm.ee 44 points 2 months ago

the scientists have inadvertently discovered that this squid is also a witch

[-] thefartographer@lemm.ee 40 points 2 months ago

Impossible. It's under water, which means that it weighs more than a duck.

[-] KillerTofu@lemmy.world 22 points 2 months ago

Who are you, so wise in the way of science?

[-] Zorque@kbin.social 15 points 2 months ago

A former newt

[-] AtariDump@lemmy.world 13 points 2 months ago

I see you got better

[-] gregorum@lemm.ee 14 points 2 months ago

then this suggests that our knowledge of ducks is also in error

[-] Annoyed_Crabby@monyet.cc 4 points 2 months ago

It's a Squitch!

[-] Churbleyimyam@lemm.ee 7 points 2 months ago

Not even humans have yet figured out how to reproduce a Colorchecker Passport.

[-] nifty@lemmy.world 3 points 2 months ago

Squids been doing this for millions of years before humans started to science

[-] ieatpwns@lemmy.world 2 points 2 months ago

I see Paul is up to his usual shenanigans again
