The Insane Biology of: The Cuttlefish

[@joshuazeeman7553]

My favorite part about cuttlefish is that their pigmentation changes while they sleep and will sometimes just explode with brilliant displays of color without any outside stimulus. We may never know why this happens but it really seems like some reflection of their dreams.

[@MichaelWinter-ss6lx]

Of course it's reflexions of dreams. We should by now be very sure that animals dream. Who has not seen a dog dream of running, or the cats tail go wild while she sleeps? We should assume dreaming to be the norm. At least by intelligent creatures.

[@RaymondThePainter]

I've heard that they're able to achieve REM sleep (the state of sleep in which humans usually dream). So they're likely able to dream.

Cuttlefish have also demonstrated the ability to pass the Stanford marshmallow test - deferring gratification in order to obtain a larger reward. Watching footage of the tests is fascinating, as the cuttlefish display a lot of the same self-distraction techniques used by human toddlers taking similar tests.

[@SelkieTears]

the only time i've ever snorkelled in my life as a little kid, I had the pleasuere of meeting a little cuttlefish i was so surprised I just stopped for a second and stared and the little guy stared back before shooting away. I've never felt like I've been regarded by an animal like that before - it really felt like it was actually considering me before deciding I wasn't anything interesting and going on its way. I love cuttlefish so much, my favourite cephalopod for sure 😊

11:35 The chromatic aberration would not be limited to RGB, that would allow distinguishing a whole lot of spectral colors within the range their photoreceptors are sensitive to, the limiting factor for a cuttlefish is probably processing power if that is how they are detecting color. RGB wouldn't even be the easiest/most likely if their vision is based on this and only processing three colors.

[@2424Lars]

It's a very interesting way of doing spectroscopy, I wonder if there's any real world applications for this

[@pyropulseIXXI]

Processing power? Really? No, their 'processing power' is not the limiting factor; they don't even have 'processing power;' their brains are not CPUs or computers. Also, just to let you know, the worlds most advanced super computer and AI cannot even model the behavior of a simple FLY in a real time simulation, yet a simple fly brain can do all this using a fraction of the power and a fraction of a fraction of a fraction of a fraction of any supposed 'processing power.'

I am so happy that you covered the Cuttlefish. As much as I think of Octopusses as aliens, when I look at a Cuttlefish just **exist** I'm like, what fricking asteroid did you arrive on? The way it's mouth is positioned behind the little arms is so peculiar that one can't even tell where the heck the mouth is or whether they're looking at it from the front or the back even after many times of looking at this creature. Everyone wonders what sci-fi creatures from other worlds would look like and I'm literally here going "Duide. Have you even SEEN The insane Biology of the cuttlefish??

Here in Australia I find “cuttle bones” on the beach all the time. Birds love them. If you tie a bone up in their aviary, they’ll use it to sharpen their beaks and as a calcium supplement. You can buy them in pet stores too. I assume it’s the same in the USA?

I saw a cuttlefish video showing one individual who had a potential mate on one side of him and a rival on the other. He was simultaneously flashing the mating pattern to the female and the aggressive warning pattern to the other male. The control is amazing.

Don't know what they were up to, but seeing that was enough to mesmerize me, Cephalopods are such amazing creatures.

Is it possible that the cuttlefish's habitat and the ability to camouflage perpetuates a cycle of increasing intelligence? Visually complex habitat -> camouflage creates advantage -> needs larger brain to camouflage better and control appearance with detail -> more cuttlefish with better camouflage and shape-shifting -> need more brains to be able to compete -> more cuttlefish with better camouflage and shape-shifting -> need more brains to be able to compete -> ....

[@notfunny3397]

Kinda interesting to note than even though we think of octopus and squid as pretty closely related, the fact that they have a different amount of limbs kinda suggests they are pretty distant. When's the last time you saw a primate with more than 5 limbs?

[@michealwestfall8544]

Not really, it's easy for extra tentacles to appear through mutation and be useful. It's just muscle. But with skeletonal limbs, it's much harder since it needs to mutate an extra appendage with bones that connect to the rest of the skeleton; that at the very least isn't detrimental to its survival. Like fingers and toes.

[@nordveld]

I would rather think of this like whales, who are descendants of ungulates who have four extremities. Whales, however, have two. Speaking of cephalopods, Nautiluses have many tentacles, squids and cuttlefish have eight plus two, octopuses have only eight. So - it is possible.

[@Puzzles-Pins]

You realize it's not much different than some primates having a tail? Monkeys and apes are related, both primates. Squids and octopi are related, both cephalopods.

[@blahthebiste7924]

[@_Solaris]

I've always wondered about that for fish in general.

[@2424Lars]

Every living organism produces gas with their respiratory system, which is then pushed in and out of the swim bladder, and presumably the cuttlebone for cuttlefish. Swim bladders are what our lungs evolved from, and several species of fish can use this swim bladder to breathe oxygen from the air.

Their bone was also used in jewelry making to create lost molds (molds, that can only be used once, similar to molds made of sand) to cast objects. Though, since you're limited by the size of the bone, it was usually smaller objects, like rings.

An interesting thing about evolution is that cuttlefish don't even need to be able to see colors to reproduce them. The cuttlefish is just displaying pattern X to repel predator Y in environment Z or pattern A to attract prey B in environment C. In the same way that predator pressure forces butterflys to have certain patterns and certain colors, predator or prey pressures may have forced a slew of patterns and colors into the cuttlefish repetoire. Cuttlefish which displayed the wrong patterns got eaten or starved, cuttlefish displaying the better patterns live on to breed.
