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 3 месяца назад

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.

@raymondmcyeetface6850 19 дней назад

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.

@allisonbergh4429 5 месяцев назад

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.

@benjaminanderson1014 5 месяцев назад

Imagine being male and hanging out with a woman and her husband, and wearing drag on the half of your body facing the husband and normal clothes on the other half, and convincing the man you're a woman who wants to sleep with him, while simultaneously sleeping with his wife.

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 😊

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?

@vice.nor.virtue 5 месяцев назад

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?? It makes Avatar look like a documentary about goats, horses and pigeons".

@TrabberShir 5 месяцев назад

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 5 месяцев назад

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

@pyropulseIXXI 5 месяцев назад

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.'

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

@notfunny3397 5 месяцев назад

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 5 месяцев назад

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 5 месяцев назад

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 5 месяцев назад

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.

@rontropics26 5 месяцев назад

@@seansingh4421 I think all cephalopods are hard to keep! Perhaps easiest but still not easy. I’ve had a couple octopus too, one was pretty easy and one was super picky. Cuttlefish need a constant supply of high quality live food. As long as you ace that part you’ll be golden. If you have experience with a reef tank you’ll be good too because cutttles need perfect stable water quality similar to coral.

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 -> ....

@2424Lars 5 месяцев назад

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.
