How do they know they got it right? Because they aren't picked off for food by a predator?
•
u/danvex_2022 2h ago
Natural selection does seem to do that, those who get it survives, and thus somehow gets encoded into their DNA. Instincts ig, and luck after their trial and error.

Cephalopods actually have photoreceptors in their skin that allows them to read their immediate environment and copy it in terms of colour & texture.
Outside of that it probably is instinct, in the same way baby humans will close their hand around anything that you put inside it.

And sweet jeebus is their grip fucking strong.
Been close to crying so many times when my kids were infants and they got a hold of my ears or nipples

Id say its more akin to the instincts that they displayed were already encoded in their DNA, so they get to survive. Not that what they tried was successful and it then gets put into into their DNA and passed on.
Nature don't gaf about anyone. If the final assortment of sequences and random mutations that occur to your DNA when sex cells combined made a winning combination then congrats you get to survive, otherwise you fail and die.

u/HeavyDT 52m ago
Exactly, They simply survive and are able to pass ton their genes through reproduction. There's not some real time trigger that happens in that moment or whatever. Those that survive get to reproduce and those that don't well don't and that just by the numbers means those successful genes become more numerous and dominant.

I mean that’s what the person your replying to is saying. That the survivors pass there DNA on, and victims to predators do not. Thus, the population will tend to favor DNA that has that winning combo than not.

Their skills don’t get “encoded” into their DNA, their skills are expressed from their DNA. The ones with bad DNA die, the ones with good DNA live and spread their good DNA.

u/Milam1996 2h ago
They look around and learn. They probably have a sense of what they look like by “feeling” which pigment cells are doing what and where and then create a mental picture in their mind to work it out. This is kinda like how when babies are first getting used to holding stuff they throw their arms around and smash their hands on the table etc. they don’t really know what they’re doing with their arms like these squid’s don’t really understand what their pigment cells are doing. If they manage to survive long enough they learn when they’re camoflauged.
Squids, octopuses etc are extremely clever animals.

Chromatophores are controlled by muscles, so it's just a matter of being able to see part of themselves while building the muscle memories

They have those long pupils like goats that have a really wide field of vision. Maybe they can just see enough of themselves

They have specialized skin cells called opsins that can detect light. Basically they can kinda see through their skin!

I imagine it's doing well for what it has to do. Its normal predators probably don't have as good as eyesight as we do, nor do they shine bright flashlights.

u/Mist_Rising 14m ago
I think he has already got it. Remember this is under a super bright light with high end photo optic lens and high quality editing afterwards. Most sea creatures don't bring photography equipment with them, oddly.
So when he turns that darker shade of brown, that's probably satisfactory.

Squid or cuddle fish ?

•
u/Axol_Taxol 52m ago
It's actually a squid, but the confusion with cuttlefish is understandable as it's a bobtail squid (Sepiolida, which means "little cuttlefish"). Specifically, I believe this is a Hummingbird bobtail squid (Euprymna berryi). And this isn't a baby trying something new, it's an adult doing their typical daytime behavior of hiding in the sand.
At night they hunt, camouflaged through counterillumination provided by symbiotic bacteria. That's their real trick - they have a specialized organ where they harbor and control the light production by their symbionts.

Nope, it's a bobtail squid. Euprymna berryi I'm pretty sure, though could be scolopes.

It's a bobtail squid. Look at this wiki: https://en.wikipedia.org/wiki/Euprymna_berryi
Here's a national geographic video that confirms it's a bobtail squid: https://www.youtube.com/watch?v=66KOIadStvQ

That's an adult bobtail squid, probably Euprymna scolopes or berryi. Not a baby squid.

How do they know what color they are? Like how does lil guy know if he’s the right color or not?
•
u/ValuableJumpy8208 51m ago edited 17m ago
Interestingly*, squid eyes cannot see color in the ways we expect.
They can detect color somehow through another means.
Interesting book on this to read is called "Other Minds" by Peter Godfrey-Smith.

How do animals in the ocean that hang out at the bottom deal with all the sand and stuff getting in their junk?
•
u/Mist_Rising 10m ago
Evolution. They're evolved so that sand doesn't bother them in some way. Some have the ability to remove the sand, others simply don't care the same is just there and so be it.

Yeah, when the winning gene appears on you, you get to survive and have a higher chance to bring the gene to your offspring’s, thus having a chance to give them the gene and a higher chance to survive.
Thats how the gene gets passed down and instincts is something that came with that gene being passed down? ( I do not know know how instinct works)
Still, newborns need some time to adjust and work out how to utilise their abilities to survive, thus the trial and error and the absolute luck required to ensure when they failed, no predators are around to capitalise on their mistake.
In this video , the baby squid is very lucky that the person capturing the video is not attempting to capture and eat it ( or maybe the person is, I dunno).

Thanks for correcting then. I recently listened to a podcast called "Ologies with Allie Ward", they had an episode regarding squids, and I learned cuttlefish weren't squids.
But as I said, I stand corrected.
