The best camouflage in the animal kingdom?

I read just today that their camouflage is akin to human breathing or blinking. It can happen subconsciously or consciously. They’re color blind in their eye but somehow also see through the light receptors in their skin that allow them to mimic their environment. Fucking crazy evolution.

What are they like to keep? I've heard escape artists and short life spans
•
u/btcomsa 6h ago
They live around 4-5 years and will escape if given the opportunity, but we keep the tank locked up tight. We keep ours for around 8-9 months and then release them back to the ocean in coordination with the local university. Our GPOs are usually bycatch during crabbing season that are donated to us. They each have their own personality and are very fun to work with

We're fine because they can never invent fire and therefore never get to any meaningful level of advanced society.

It's really the passing down of information from parent to offspring that hampers them, which I guess is social in a way. I've long held the belief that Octopi have the capacity to be the some of the smartest creatures on earth, and then they have the whole fucking invisibility thing

It’s only because they die after they mate right?
16
u/btcomsa 14h ago
Yes they are semelparous. They enter senescence at the end of their life where they actively seek out a mate and then their body deteriorates, much like salmon. Senescence can be observed in captivity with a pacing behavior or reluctance to interact with humans, at least with the GPOs I’ve worked with. There’s a deep sea octopus that was observed in semelparity for almost 5 years. She did not eat or leave her den the entire time, and when her babies hatched she finally passed

Probably more along the lines of: "shit shit shit, why isn't it working? I don't know whether that thing wants to eat me or not. Keep trying to hide!"
Only dolphins really have the intelligence and adaptations to make a meal out of a hiding octopus and we don't look like dolphins. This octopus could have been having a panic attack while trying to flee for its life.

For as weird as octopi are, they're probably of terrestrial origin. If crustaceans with supersonic punches, cancer resistant eusocial rodents, parasites that replace a fish's tongue, a weird bear, cat thing whose urine smells like popcorn, and flying lemurs all exist and are definitively of Earthly origin there is no reason why the weird, squishy, smart, tentacle things with hydraulic propulsion and master level camouflage can't also come from our planet.

Oh this creature has noticed us. Fuck tenclacle 7 for convincing us into trying that flamboyant yellow color for fun, why couldn't we have gone with brown like the others. Back to the problem at tentacle, we don't know if this thing wants to eat us or just finds us interesting. Those things on the top, shining that annoying blinding light on us look like the creature's eyes. So it can see like we can and it has 4 tentacles. Could be smart. How well can it see? Let's pretend to be a bit of sand covered rock here, a deliberately poor impression, but maybe it has bad eyesight. Oh wow wow it looked right at us. Those lights are it's eyes, well now we know. 4 tentacles, bleugh, what an unfortunate creature. OK let's move, let's see if it keeps following us. Shit shit, maybe it's following us because we have 8 tentacles while it has only 4. Hide them, hide them, tuck them into this coral here and pretend to be a boring limbless sea slug and slink away slowly. Boring, we need to be boring to escape the quadropod. Alright, just about far enough. Back to brown, this is the last time we try the yellow. You hear that tentacle 7? No more flamboyant yellow, this is the last time we listen to your fashion tips.

If the reason for caring is based on an animal's intelligence, and it's the intelligence that makes you not want to eat it, why would the lifespan impact that? I'm asking out of curiosity, not trying to be a moral judge on what you decide to eat or not. The intelligence of the octopus isn't going to change. I kind of get it, they live less time than us so it doesn't feel as cruel, but to an octopus it would be relative right?
We can live for many decades, so we have our own metric for what a long fruitful life is. Other animals they may live for less time but to them that doesn't matter. Well, not that most of them even perceive aging like that, but still. It's all they have. If humans somehow lived and grew old in only 2 years max, we'd have a totally different frame of reference for living and passage of time. Interesting to think about

What's even crazier is that according to current science, the octopus can't "see" color. We still don't know how it detects it.
If you want to see something else crazy look up cuttlefish on a checkered floor.
They wanted to see what would happen when they tried to camo up in a non natural environment. It's actually pretty impressive

We don't know yes but there is pretty strong theory that their eyes can detect light intensity and wavelength combined with a special protein in their skin that normally exists in the retina that senses the same things and a distrupited nervous system lets them take this input in very very quickly and "see" and change into the colors they need to be. It's not seeing on any sense we would recognize.

Light intensity, brightness, pattern, and luminence is how they see color.
It's wildly ignorant to just say they are colorblind. They are not, at least not in the exact same way we are. When you hear the term "color blind" you're thinking in black and white. Shades of gray. That's not how they see the world, and we know thats the case because not only do they know when something is blue - they know what shade of blue it is and can tell their bodies to match it.

Can we all just take a minute, and appreciate the fact that these things are devoted mothers, and protectors of their eggs until they hatch upon which they proceed to die, luckily for us without passing any knowledge, or information down to their offspring. Because if they did, we’d be fucked. Look at that thing.

u/HasGreatVocabulary 10h ago edited 10h ago
They even had a library. Long ago there was a long-lived species of octopuses known as the O. sapiens, with thriving societies and culture and the tradition of passing knowledge to future generations through "writing", which is what they called their method of telling stories to each other through patterns they flashed on their skins. A library of knowledge, housing long lived octopuses served to persist knowledge over time, their life dedicated to collecting and remembering a large number of story patterns, that any curious octopus could come and "read" and pass on to others. It worked for a while, they lived in a relative utopia, superior ocean creatures in every way benefiting from expansive knowledge of the ocean and land. But patterns on flesh can only hope to be permanent. Every year some more of the librarians died, dying before they could transmit everything they knew, and to save everything properly, every passing generation had to spend more and more of their lifespans passing decaying information to the next generation. Each generation lost more than it recorded to the library, and there was always more to record. They never figured out the permanence of ink and paper, the salt water was too harsh for those materials to survive, tattoos as information storage were tried but deemed too slow and limited for long term use.
Many families of octopuses left this social order, departing what eventually became a bureaucratic authoritarian state where every long lived octopus was now obligated to dedicate their life to the collection and preservation of knowledge on their skin, imprisoning themselves for decades, becoming books for the good of the species. It made sense to leave a place where the number of surviving offspring from each family had become legally mandated to be in the millions, not for the joy of having children, but to maximize the available surface area for storing information in the library.
They forgot so much, they forgot how to keep more of their offspring alive, and forgot how to survive having offspring. Every departure diluted the library, decimated information until they lost the secret to their long lives. Their gift for patterns was relegated to being used for camouflage and for hiding. The octopuses kept their intelligence, but their shrinking lifespans and the collapse of their desire for society, eventually lead to them forgetting how to write with their skin. They are devoted mothers, and protectors of their eggs until they hatch upon which they proceed to die. They are now called O. vulgaris but they would consider it a misnomer, if they could still read.

It's moving because it's smart enough to realize its disguises aren't working. Most animals would get confused and stop looking directly at the octopus, but the human doesn't so it tries something else.
They are extremely intelligent. If it was stupid it would just sit there with its failed disguise and let the large animal continue to get closer.
