Daily fish fact #714

Mandarinfish!

The mandarinfish is one of the only vertebrates to produce blue cellular pigment! Most other blue vertebrates’ colour is caused by structural colouration, as in microscopic structures that reflect, refract and otherwise alter light. The mandarinfish and its relative psychedelic mandarinfish possess cyanophores, however, which contain blue pigment itself!

Six Sentence Saturday

I was tagged by the lovely @faelanvance - thank you!

Rules: Share the six most recent, or semi-recent sentences of your WIP.

He closed his eyes and settled in for another long night of uncomfortable turning and shifting positions, waiting for the dawn to come and relieve him. Nathan remembered sleeping with the light on as a child, afraid that there was someone hiding in the shadows; but somehow it was worse, now, knowing the reverse.

The truth was that there was nothing there: nothing in his closet, nothing under his bed, just an empty room, and an empty life. He turned off the lamp, so he didn’t have to see. In the darkness, he could still pretend. Mostly he replayed moments in his life, wondering how things might have turned out if he’d played his hand differently. Nathan didn’t live in regret, but he was certainly a regular visitor.

I am tagging recent visitors @cyanophore @manganese-heptoxide @naometry @arigalefantasynovels and anybody else who'd like to share!

Six Sentence Sunday

I wanna thank you @cyanophore-fiction for tagging me for now open tag.

I don't really have 6 sentence because I'm still thinking the scenes but here's one that my mind managed to conjure.

As you walk alongside Garett and Lucas towards the castle, your eyes dart around the surrounding area, taking in the sights and sounds. The trees sway gently in the breeze, the leaves rustling softly as if whispering secrets to one another. But your thoughts are far from the peaceful scenery.

A nagging question keeps surfacing in your mind, like a persistent itch you can't scratch. "What are Lucian and Variel up to?" you mutter under your breath.

(Meanwhile)

(Lee's POV)

"Lucian get close and don't wander far!" you shout to a drifting away Lucian.

"Variel don't touch that!" you shout to a Variel who is poking a dead fish with her nails.

"I'm gonna die!" you groan out in exasperation.

"ACHEM?" you hear behind you and you felt a tap on your shoulder.

"What?" you turn around and see a merchant pointing his finger behind him.

You quickly spun around to find Variel standing amidst a raging inferno she had created with her hands and Lucian fighting the flames with a bucket of water.

In shock, you yelled in frustration and stuck your hand in your pocket, “I'm not having any kids in the future!”

Six Sentence Saturday

@cyanophore-fiction tagged me in this. While I am tempted to just put a block of thesis here that’d feel like cheating, but I haven’t been writing much else so this is from Old Mousebow, Adventure 3, I think.

The idea here is to post 6 sentences from something you are working on and, well, I think this project counts. Need to keep writing and editing it before I put it on the appropriate pages. Regardless:

It was noon when Helies shifted and started looking for something to drink. There was a stream nearby, and after slowly scanning the area, he started to drink. Despite a few sounds that would make most stags start he moved slowly and deliberately, careful not to wake Theodore up. He ate from some bushes that were at head height and even an apple that had been caught by some branches.

Theodore woke up a few hours after noon, his hammock gently swaying as Helies moved below him. The sun was warming his snout. 

Theodore is the mouse protagonist. Helies, appropriately is a stag.

I just realised how few people in the writing space I actually know here - or more specifically, how many have stopped posting. I know @lexiklecksi writes some great stuff, but other than that I’ve really fallen out of touch. Feel free to participate if anyone sees this obv. I’d love to read some snippets

[today-i-am-thinking-about]

how there are only a few animals that actually produce blue pigment

[earthstory]

Amelanism Previously I wrote about melanism (https://tmblr.co/Zyv2JsYpZGm-qa00), amelanism also exists and is characterised by a lack of melanin pigments (making it the opposite of melanism). Melanin is a pigment produced from an amino acid by a melanosome. Amelanism can affect a range of animals including fish, mammals, birds, and amphibians. However, difficulty in producing melanins affects these groups of animals differently.

In mammals, if a melanosome is unable to produce melanin, no pigment is produced. As such, the mammal has white hair, pink skin, and pink, red, or violet eyes. Hair is affected by the lack of melanin, as in a normally functioning melanosome, melanin is produced and then engulfed by a cell. When this cell happens to be at the root bulb of a hair, the hair takes up the melanin pigment. A complete failure of the enzyme that allows production of melanin an organism produces a condition called albinism, where there is no pigment in skin, hair, eyes, or anything else. However, this condition is particularly rare in nature as it is difficult for organisms with this mutation to survive; many organisms instead have varying degrees of amelanism, where only one portion of a body is lacking pigment. In other vertebrates such as fish, birds, and amphibians, things happen a little differently. These vertebrates produce a wider range of pigments via chromatophores (for example xanthophores produce yellow pigment, erythrophores produce orange pigment, and cyanophores produce blue pigment). Therefore a lack of melanin affect pigmentation differently, so amelanistic vertebrates are less likely than mammals to have pale skin and red eyes. ~SA Image: http://bit.ly/1gl4Qob

[lesbian-octoling]

what color do you think an albino inklings ink be?

First off, this would probably be very rare- it’s most common in birds, reptiles, and amphibians, less seen in mammals, and almost never seen in other taxa. Mollusks are an exception, because there’s actually a lot of mollusks that are very commonly albino, often passed down hereditarily. Unfortunately, most of the time, these are snails. I can’t find *anything* on albino squids or octopi. This is…w ell, probably because they can change color, and white is often a natural color for them, so it would be impossible to tell if they were or not. It would also be exceedingly rare if possible because they rely completely on their camouflage to survive- if they can’t change color, they will die. 

Obviously, not in the world of splatoon- they no longer rely on camouflage to survive. So it’s possible there could, theoretically, be albino cephalopods… but we don’t know anything about them in real life (because we don’t have any live specimens), so it would all be speculation. 

But… let’s first look at the cause of albinism. Albinism is the lack of pigmentation in the body. However, theres lots of types of pigmentation! Lots of animals have several types of chromatophores- colored cells- including melanophores, xantophores, erythrophores, leucophores, cyanophores and iridophores. However, albinism usually only affects melanophores- which produce melanin. This is the stuff most commonly used by animals, and is one of the only ones used by humans. There’s other, more partial types of albinism that affect other cells, or ALL pigment cells!

But let’s just go with the most common one- the one that erases melanin. This would mean that the inkling wouldn’t have any of their normally colored chromatophores (the reds and blues and all that fun jazz). 

However- most albinism doesn’t affect iridophores (iridescent cell structures) or  leucophores (reflective white structures), both of which squids have! This is what gives squids that beautiful iridescent color- the iridophores aren’t actually colored, they just reflect light, making them LOOK colorful, like this! 

The dark spots are the color changing chromatophores, and those shiny greenish bits are iridophores, and the white stuff behind that, leucophores!

Now, the ‘albino’ inkling couldn’t have those dark chromatophores, so… essentially, the would be white. However, if they still have their iridophores and leucophores intact, they would be iridescent and reflective. This means that they would sort of look white, but with a sheen or tint of whatever color is reflecting off of them (on their tentacles, at least- i’m not sure if inklings would have iridophores in their ‘human’ skin).

Now, as far as ink goes- squid ink is colored black with melanin, so obviously, that wouldn’t be there. But before squid ink is colored- it’s actually clear! However, if you’ve noticed that inkling ink is glittery especially in hero mode- makes me think there might also be some sort of iridophore in there too? So…

So the answer you’re looking for is an albino inkling’s (or octoling’s) ink would be completely clear (not white!), except for the possibility of the ‘glitter’ commonly seen in hero mode.

Find the vibe tag

I was lucky enough to be tagged by @avrablake - thank you again!

My vibe to be found was What are you doing?, which I have to concede I found pretty difficult. There was one scene around sign language, but it was pretty much soaked in spoilers so I'm not going to go there. Instead, I've taken a slightly different approach along the lines of 'What are we doing?'

From Going Quietly:

“Speaking of which, what are we eating today?” It was only then that Nathan realised that he hadn’t. In all the excitement, he’d skipped straight back to work from Ghost Town Coffee, and forgotten to pick up lunch along the way. No wonder he was feeling tired. He would have to watch that; his newfound balance had to hold. “What are you feeling? Mexican?” “Still half-Colombian, actually, but it’s okay if you’ve forgotten. I get that all the time.” Then, before he could find the words for a protestation, she looked up at him and smiled. “Sure. Did you have anywhere in mind?”

I'm tagging recent rebloggers @xansmenageriereblogs, @cyanophore-fiction, @awordchemist with no pressure, and leaving the tag open for anybody else who'd like to participate!

Your vibe is "I get that all the time" or something thereabouts.

[lagtim3-archive]

So the first word-prompt I got was ‘Earth - Loab’ and I was initially gonna do a thing that’s like a PIG write-up of Octalien biology... but that would probably be kinda of a boring read when you’re expecting character-interaction type stuff.

That being said, I’m still gonna make it and post it as it’s own fic-thing later, but I did take a buncha notes and here’s the only segment I have a draft finished for, the ‘coloring’ segment:

Octaliens have a six-layered dermis, with each layer containing it's own unique set of chromatophores--pigment-containing cells. Octaliens can rapidly change color through muscular mechanisms that change the size of and reorient reflective plates within chromatophores. This process is called 'metachrosis'. 

From top layer to bottom layer, each skin layer contains:

iridophores        (reflective / iridescent)

leucophores      (white)

xanthophores    (yellow)

cyanophores     (blue)

erythrophores    (red)

melanophores   (black/brown)

Octaliens are carnivorous, and rely on a balanced diet in order to keep a constant supply of pigment. For instance, an Octalien on a carotene-restrictive diet would have their red chromatophores rendered transparent, and thereby useless. 

Each chromatophore type requires a specific molecule/compound type to function:

Iridiphores and Leucophores rely on guanine. Guanine is found primarily in the exoskeletons of what would be analogous to Terran crustaceans.

(Note: The difference between these two chromatophore types is all in the structure. Iridophores have a looser crystalline structure, which allows for the scattering of light, giving them their rainbow-iridescent effect. Leucophores, on the other hand, have a more organized crystal structure, which aligns lightwaves and reflects white light.)

Xanthophores rely on pteridine. Pteridine is a very common chemical compound found in the chitin of most Octalian arthropods, primarily those us Terrans would liken to ‘insects’.

Cyanophores rely on a biochrome compound unique to Octalia (Cyanic acid), found primarily in the fruits and roots of a very common family of tree found world-wide. While the fruits and roots themselves are indigestible to Octaliens (being carnivores), they are the primary diet of a genus of very small arthropods that incorporate the pigment into their own chitin. Visually, they could be described as blue, land-dwelling krill. These arthropods are often dried, ground-up, and used as a supplement/coloring in other foods. 

Erythrophores rely on Carotene. Dietary Carotene (and Pteridine, as well) is primarily found in a unique form of Octalien life similar to corals, but mobile in much the same fashion as tumbleweeds are. Carotene is also found in the organs of what could be compared to Terran fish.

Melanophores rely on the presence of eumelanin. Eumelanin is the only coloring compound generated by the Octalien body. In the absence of all other pigment types, Octalians are a washed-out, grey-tan color. The guanine composing the Leucophore layer is not capable of reflecting UV light like it is visible light; therefore, the Melanophore layer of dermis is also the layer responsible for protecting the internal organs from UV damage, and as such can 'tan'.

Mandarinfish 

Fun Fact: To date, only two vertebrates have been found that have blue coloring as a result of cellular pigment called cyanophores. Both the Mandarin fish and the closely-related psychedelic Mandarin (also called the picturesque dragonet) are vividly-colored fish native to coral reefs in the Pacific Ocean. You might say that these small, stunning fish, which are popular in the saltwater aquarium trade, are the only animals worthy of being called true blue.

[mochascope]

Did You Know 🐠 Mandarinfish is an exception, since it has special chromatophores called cyanophores that contain blue pigment. They do not need scales to protect themselves because, their bodies are covered in toxic spines and coated by a thick, foul-smelling mucus.

Beware of the beautiful but poisonous Mandarinfish Have you ever heard about #Mandarinfish. No Debut that this fish is a most beautiful fish in the ocean, known for beautiful colors, that seems to contain an #InternalLight that makes it glow at all times.This #fish is one of the most searched for creatures by underwater #photographers so they can be captured on camera. Despite its own light, the Mandarinfish is very shy and prefers to appear at night, when they go out to mate. Colloquially they are called #Mandarin because they resemble the legendary #ChineseDragons. At home in the sheltered #lagoons and inshore reefs of the Pacific Ocean, ranging from the Ryukyu Islands off the coast of Japan, to warm Australian waters, this little dragonet is covered in tiny spines to inject a toxic mucus into anyone who tries to handle and/or eat it. The #Mandarinfish is one of just two confirmed species in the world that can produce its own blue colouring. Along with its close relative, the #psychedelic Mandarin (#Synchiropus picturatus), the mandarindish produces ‘cyanophores’ – #blue #pigmented, light-reflecting cells – to achieve its vibrant colouring. The vast majority of blue-hued creatures on Earth have to resort to elaborate optical illusions to brighten themselves up, with microscopic layers of colourless crystals in their skin layered in such a way that they reflect #bluelight back at any onlooker.

Mandarin dragonet: Synchiropus splendidus •Distribution: The mandarinfish is native to the Pacific, ranging approximately from the Ryukyu south to Australia. •Lifespan: 10 to 15 years in the wild. •Size: Up to about 6cm. •Diet: They feed primarily on small crustaceans and other invertebrates. •Conservation status: No special status. •Dangerous: It has spines that will stick the hand of anyone who tries to touch it, and it produces toxins that can be dangerous — especially if they come in contact with open wounds. •Did you know?: S. splendidus is one of only two vertebrate species known to have blue colouring because of cellular pigment, the other being the closely related psychedelic mandarin (S. picturatus). The name "cyanophore" was proposed for the blue chromatophores, or pigment-containing and light-reflecting cells.
