electroreceptors

oops I took that chimaera/rabbitfish-inspired Zora I doodled and made them into a full-blown character

her name is Ponzu because I was out at a sushi place, saw a bottle of the sauce, and suddenly this grump fish decided it was her name

cartilaginous fish have electroreceptor pores on their snouts, and they’re especially apparent in chimeras - so I had an excuse to give her “freckles”.

Four little snippets, just little things that happened after the last video.
This was requested by @anxietyandlogic

hope you enjoy :)

1. Jokes.

“Seriously what did you do to him?”

Anxiety smirked, desperately attempting to hide his laughter.

“Calm down Princey, don’t get your royal knickers in a knot-”

“Hey!” Shouted the noble indignantly.

“We had a debate and some things were cleared up-”

“Wai-wait, you had a debate? With Logic?”

“He said it went well-”

“Huh, that’s interesting…”, Princey paused, placing his hand on his chin pensively. Then he turned without a word and walked away.

Anxiety frowned, he wasn’t sure what exactly was Prince’s deal but now he didn’t feel too good about the debate. Sure he didn’t try but did Logic mean what he said?

He turned, from this angle in the kitchen he could see Logic on the living room couch. He had to ask.

But of course, being Anxiety, he couldn’t. So he settled for a different question.

“So what was that? With the jokes?”

The Teacher looked up from the book he was reading.

“Well, I am a proud philomath, when I learn new things I’m happy to take any opportunity to use what I’ve learnt, even if that does mean taking on a childish sense of humor”

Anxiety scoffed in amusement.

“Sure that’s what you learnt from me-”

“Among other things yes, it really was a good debate”

There it is, he said it, no deciet, no hidden meaning.

The darker trait gave the other a small smile- it was more of a not smirk but you get the picture.

2. Bonding.

After the little conversation, Logic had gone back to reading and Anxiety took the opportunity to scroll on tumblr.

The younger persona was stretched out on the couch, happily tapping on his phone, though he was on the same couch, Anxiety’s legs still had far to go before he could reach to Logic.

Either he was pretty short or Logic just didn’t take up much space. The latter seemed more plausible to Anxiety.

They were quite content in their silence.

For a while atleast.

He wouldn’t admit it but hearing Logic’s alarm go off, caused him to jump and he barely bit back a yelp.


“Sorry about that, there’s a documentary coming on that I don’t want to miss”

“What, some phsycology thing?”

“No actually, it’s about the deep ocean, did you know that we’ve explored more of space and only approximately 0.5%-”

“Of the ocean and 95% still remains a mystery?” Anxiety joined in.

Logic grinned at their simultaneousness. Truly intrigued that he’d have another person to discuss the topic on, Thomas wasn’t really fond of it much.

“Would you like to watch it with me?”

“Sure”, the darker trait shrugged, “got nothing better to do”

—–

“It’s so tiny, holy sh-”

“Anxiety, mind your language-”

“Wha? Bu-but you gotta come see this!-”

Morality who had just happened to go into the kitchen at that precise moment, rolled his eyes at the younger’s language before walking over to see what Anxiety was so excited about.

“See wha-? Aaaaah! That. Is. Adorable! What is that little creature?!”

“I heard adorable, what is the adorable creature and can I pet it?”, bellowed Princey from somewhere in the hallway.

“Not unless you go to the bottom of the ocean Roman-”, called Logic with a slight chuckle.

“Wha?”, the Royal was utterly confused, what adorable thing could possibly live at the bottom of the ocean?

Prince came in, joining the others in the living room.

“Oh my fairy godmother, that IS adorable! What is it Logan?”

“It’s adorable”

The other three paused and looked at him.

“What? That’s what it is, it’s the adorabilis octopus or the opisthoteuthis adorabilis, it literally is adorable”

“Ohh”, mumbled the other three together.

—-

“There’s no way that thing isn’t blind”

Prince and Morality had lost interest after the documentary stopped focusing on the tiny octopus.

So it was once again just Logic and Anxiety.

“It’s quite possible, it lives in a depth with no light, it probably doesn’t need it’s eyes-”

“Nah, with it being that blank, it’s gotta be able to sense something electrosatically, or what’s the point of it even having eyes”


Logic was going to give his input when the documentary beat him to it-

‘The Ghost shark or Chimaera is indeed blind however it does sense it’s prey with electroreceptors, it is able to sense them electrosatically’

“Hey, I was right!”

“Huh, it seems that you were”

 Logic smiled, this was one of the very few times he’s ever seen the younger so interested in something.

—–

3. Quiet.

When the documentary ended, Logic went back to reading his book and Anxiety went right back to lounging on the couch, content with scrolling on his phone.

The Teacher could hear the music blasting out of Anxiety’s headphones, he couldn’t hear the lyrics, but the beat was…strangely neutral?

It was no doubt a metal or alternative rock song, not really his taste but the beat was constant so he didn’t mind.

—–

He had lost track of time in the constant buzz of music and the otherwise silence.
He was so absorbed in his book that he actually jumped when he heard a light ‘Thud’ coming from his right.

Anxiety’s phone had slipped from his fingers and landed lightly on his chest.

Logic had turned right on time to see the younger’s eyes slip close, his breathing even out and his head to loll to the side.

The Teacher chuckled silently, before he continued to read, leaving Anxiety to sleep.

He had to admit, the other looked quite ADORABLE when he slept…ugh he really needed to stop with the Dad jokes, Morality was rubbing off on him too much.

——

4. Comfortable.

Anxiety jolted awake.

Blinking rapidly as he was quite confused as to when exactly he fell asleep.

“Oh, you’re up, you dosed off for about an hour”

'Well, that answered his question’

The Teacher could see a slight blush of embarrassment on the younger’s face, but he also saw fatigue.

“Are you going to bed?”

The darker persona thought about it for a second.

“Nah, I’ll stay for a bit, I’m comfortable”

With that Anxiety turned on his side and promptly continued his nap.

Logic rolled his eyes, but internally he was quite happy that the younger was comfortable around him.

He continued reading, this time with a small smile on his face.

New ancient sea reptile found in Germany – The earliest of its kind


A previously unrecognized 132 million-year-old fossilized sea monster from northern Germany has been identified by an international team of researchers. Findings published in the Journal of Vertebrate Paleontology.

The bizarre sea creature was a plesiosaur, an extinct long-necked aquatic reptile resembling the popular image of the Loch Ness monster, which dominated the seas during the Age of Dinosaurs.

The remains of the eight-meter-long skeleton were collected in 1964 by private fossil collectors. The perfectly preserved bones were rescued from heavy machinery excavating a clay-pit at Sarstedt near Hannover.

Despite being discovered nearly half a century ago, a group of international scientists was only recently invited to study the specimen by the Lower Saxony State Museum in Hannover.

“It was an honor to be asked to research the mysterious Sarstedt plesiosaur skeleton” says Sven Sachs from the Natural History Museum in Bielefeld, Germany, and lead author on the study. “It has been one of the hidden jewels of the museum, and even more importantly, has turned out to be new to science”.

The new plesiosaur was christened Lagenanectes richterae, literally meaning ‘Lagena swimmer’, after the medieval German name for the Leine River near Sarstedt. The species was named for Dr Annette Richter, Chief Curator of Natural Sciences at the Lower Saxony State Museum, who facilitated documentation of the fossil.

The skeleton of Lagenanectes includes most of the skull, which had a meshwork of long fang-like teeth, together with vertebrae, ribs and bones from the four flipper-like limbs.

“The jaws had some especially unusual features.” says Dr Jahn Hornung a palaeontologist based in Hamburg and co-author on the paper. “Its broad chin was expanded into a massive jutting crest, and its lower teeth stuck out sideways. These probably served to trap small fish and squid that were then swallowed whole”.

Internal channels in the upper jaws might have housed nerves linked to pressure receptors or electroreceptors on the outside of the snout that would have helped Lagenanectes to locate its prey.

The bones also showed evidence of chronic bacterial infection suggesting that the animal had suffered from a long-term disease that perhaps eventually claimed its life.

“The most important aspect of this new plesiosaur is that it is amongst the oldest of its kind” says Dr Benjamin Kear from the Museum of Evolution at Uppsala University in Sweden and senior author on the study. “It is one of the earliest elasmosaurs, an extremely successful group of globally distributed plesiosaurs that seem to have had their evolutionary origins in the seas that once inundated Western Europe”.

Elasmosaurs had spectacularly long necks - the longest of any vertebrate - including up to 75 individual vertebrae. Not all of the neck vertebrae of Lagenanectes were recovered but it is estimated that around 40 or 50 must have originally been present.

Echidna

Echidnas, sometimes known as spiny anteaters, belong to the family Tachyglossidae in the monotreme order of egg-laying mammals. The four extant species, together with the platypus, are the only surviving members of the order Monotremata and are the only living mammals that lay eggs. Echidnas live in Australia and New Guinea. Echidnas evidently evolved between 20 and 50 million years ago, descending from a platypus-like monotreme. This ancestor was aquatic, but echidnas adapted to life on land. The echidnas are named after Echidna, a creature from Greek mythology who was half-woman, half-snake, as the animal was perceived to have qualities of both mammals and reptiles.

Headcanon: Sidon, like any good shark, has electroreceptors along his brow/crest, something sharks may use to communicate with. Link, being not-a-shark, does not have these. But when Link is upset, and Sidon isn't sure how to help, he'll rub his face all over Link, sharing his electromagnetic field through touch! It doesn't really communicate anything, but Sidon acting like a huge cat usually cheers Link up anyway~

Filleted Dragon
Also known colloquially as the zombie or ghost drake, the Filleted Dragon is one of the rarest and most elusive of all dragon species. Having only been documented deep within a jungle underwater cave, it is unknown if they exist outside of this specific subterranean world.
Believed to be sequential hermaphrodites, females have not been documented, nor have eggs or chicks.
While not strong flyers they are capable of flight, though more apt to swimming as their primary form of locomotion. Their translucent skin is do to their sunless environment and renders them nearly invisible. It is not known if adult Filleted Dragons have predators but remains of adults have been documented and cannibalism has not been ruled out.
Their long illustrious fins are believed to be used in courtship or territorial displays but also act as a large radar transmitter. Lined with tiny electroreceptors,when opened, the filleted dragon can pick up the tiniest of vibrations and electro magnetic impulse being released by prey and its environment.

Three hundred millenia passion and war of Archosaur and Synapsid, and the great dynasty of the amniote, will too come to ruin. Three hundred million years after The Age of the Avian the mudsharks crawled their bellies onto dry land and inherited the world. 

The beasts of the new era is as “shark” as we bird and men are but lungfish in the mud. The final lords of the land, The Great Brnnvnnellakkak, have inteliigence far beyond our own. They see in color far into the ultraviolet and the infared, they speak words beyond our ears in the infrasound waves from their feet. Their proboscis is filled with millions of electroreceptors, used to relay their own feelings without the guesswork of primitive empathy.

The Brnnvnnellakkak believe life is but a test of God. The goal is to escape, not just of the Earth but beyond that. The universe is but an finite blot, a fleeting moment to the creator and a brief moment without vast loneliness. All universes, aware and suffering through the life that gives them a way to self introspect, are doomed to die, and the Brnnvnnellakkak are set to break the cycle of one trillion deaths. 

The Brnnvnnellakkak might be right, but they might be like us and all species who’s end goal is to run from extinction as far as they can muster.

Today I got to hug voice actor Vic Mignogna because during a Q&A panel at Otakon he mentioned his love of sharks and how he did multiple school projects on them, which is something we have in common, so I raise my hand and ask what his favorite shark is and mention I also love sharks and he tested me by asking if I knew the name of the electroreceptors sharks have which I knew was the something of lorenzini, the answer was ampulle of lorenzini, this I knew from watching a special on shark week a billion times. So basically a very popular voice actor gave me a hug because I know lots of things about sharks

Shark Week: Intro

Happy Shark Week everyone!

Every day this week I’ll be posting about a different shark or shark issue. To kick off let’s talk about what sharks are.

Sharks are cartilaginous fish, meaning that their skeleton is made of cartilage rather than hard bone. The only hard bony structure that a shark has is its teeth, and this is why the only fossils we have of sharks are their teeth. Sharks also have what is known as dermal denticles or “skin teeth”. These are v-shaped scales that are made of the same material as teeth.

Sharks have ampullae of lorenzini which are special sensory organ called electroreceptors. They are located all around the face of the shark and under the nose. These jelly filled pores allow sharks to sense muscle movement of other animals.

There are currently over 400 species of shark know to us. They range in size from 8.3 inches (dwarf lanternshark) to 41.5 feet (whale shark).

Some sharks are active hunters.

Some are scavengers.

And some are filter feeders.

Some sharks lay eggs (Oviparity).

Some give birth to live pups (Viviparity).

And for some the eggs develop inside the mother shark (Ovoviviparity).

Being apex predators (at the top of the food chain) sharks are incredibly important to the oceans’ ecosystem and help keep other populations in check. I hope you enjoy shark week and that you learn something new. I know that most of the things being shown on TV this week are going to be over sensationalized and made to make sharks seem like these uncontrollable killing machines but there is so much more to these beautiful, complex animals.

◣◣The creature opened his head massive maw, top jaw unhinging and cascading forward. His mouth opened wide in a long yawn, closing shortly and his upper jaw re-hinging back into the skull. He gave a shake of his body, sending droplets of water spraying around him, adding to the dew on the sparse grass scattered along the sand dunes.

The sun was gentle in the morning, and while he was warmblooded, the creature enjoyed the heat nonetheless. Warmblooded great whites sunned themselves after all, and he was closer in relation to them than most other creatures. At least physically.

His talons dug into the soft sand as he lumbered forward towards the sunlight dunes, enormous head low and bright piercing blue eyes alert. Twenty feet long from snout to tail, the creature was a sight to behold. A terrifying sight for some perhaps, but a sight nonetheless.

The Cetus was about to lay down on the soft ground until a twig snapped. Immediately, Bruce rose, body still and eyes scanning the forest line. Air was thinner than water, and such the electroreceptors on his snout and lateral line were weaker. In the water, he could detect muscle contractions like heartbeats; electrical pulses from each individual fish. But on land? The sense was fuzzy, and distorted.

Bruce stood idly, watching the trees and ground with a wary gaze.

CHAPTER II: An overview of the Moga lagiacrus

The Moga lagiacrus (Heres jormungandrii) is a large, predatory, euryhaline reptile and the sole species in the family Armutonitridae. It is informally known by a plethora of names, the most common being lord of the sea, lagia, and sea wyvern. The lagiacrus is the largest of all marine, brackish, and riparian reptiles, reaching a weight of 19 tons and 24 meters in length. These ectotherms are extremely sensitive to cold and are found exclusively in tropical climates, dispersed throughout the South Elde seas and coastlines. On land, the lagiacrus is capable of short bursts of speed at a “belly walk” of 15 mph, coupled with quick, agile torsions of its elongated body; in water, the lagiacrus has been observed swimming at 32 mph, although when cruising it will reduce its speed to a lethargic 6 mph.

Originally, lagiacrus were estimated to live 50 years, based on measurements of lamellar growth rings in bones and teeth. It was later suggested that these measurements may be an inaccurate way of gauging age. Lamellar rings reflect changes in growth rates, which correlate directly with the timeframe of wet/dry season transitions. The inaccurate reliance on seasonal changes and the fact that the innermost rings degenerate with time suggest an underestimation of age. A revised longevity is upward of 70 years.

The lagiacrus is a solitary hunter that frequents both demersal and pelagic habitats, patrolling the reefs and intertidal zones of coastlines. Lagiacrus are known to swim inland as well, and lurk within brackish mangrove swamps or freshwater jungles further upriver. Breeding takes place during the end of the dry season, in which the polygynous males mate with as many females as they can. They are apex predators, regularly killing and consuming any individual that wanders into their territory.

The seas of South Elde have been high-trafficked waters for thousands of years. Merchant ships passing blithely through the territories of lagiacrus were often sunken. Early Guild cartographers would depict horned leviathans mantled in lightning, with the oldest known examples of these maps dating back almost 3000 years. Indigenous peoples of the Moga Archipelago developed techniques for hunting and tracking lagiacrus thanks to centuries of cohabiting the same islands. One such technique involves chumming around the piers, conditioning local sharq populations to regularly visit the area. Sharqs are highly electroreceptive fish capable of perceiving the electric fields given off by lagiacrus. Upon detecting the lagiacrus, the sharqs flee, and thus act as an early warning system for the people of Moga. The lagiacrus is seen as a harbinger of earthquakes, maelstroms, and famine, with at least an eighth of all known shipwrecks attributed to it. Harbor and port towns such as Tanzia specialize in delicacies prepared from grilled and braised tails.

Lemon shark (Negaprion brevirostris)

The lemon shark is a stocky and powerful shark. A member of the family Carcharhinidae, lemon sharks can grow to 3.0 m in length. They are often found in shallow subtropical waters and are known to inhabit and return to specific nursery sites for breeding. Lemon sharks are found from New Jersey to southern Brazil in the tropical western Atlantic Ocean. They also live off the coast of west Africa in the southeastern Atlantic. Often feeding at night, these sharks use electroreceptors to find their main source of prey, fish. Lemon sharks use the many benefits of group living such as enhanced communication, courtship, predatory behavior, and protection. It is considered Near Threatened by the IUCN red list. Lemon sharks are not thought to be a large threat to humans.

I forget the post I saw this pointed out in, but monotremes are weird because they are the perfect blend of really old “primitive” traits as well as highly adapted specialized features.

They lay eggs and sprawl like reptiles, while also have electroreceptor covered beaks and venomous Spurs on their feet. They are just weird little fucks.

more transformers OCs with nonhuman faces plz

“visor” optics, single optics, too many optics, no optics. 

weird mouths that don’t open the way mammalian jaws do, chelicerae or mandibles and maxillae, mouths that open at the top of their head or that spiral open like an iris diaphragm camera shutter. Give me transformers who have two little mouths, one on each cheek.

features that do not correspond to human sensory organs- gimme characters with electroreceptor pits and clusters of fiber-optic vibrissae, concave surfaces that act as parabolic antennae, eyestalks and tentacles.

these are robots who are known to mess around and modify their own appearance for reasons of fashion, let’s see some weird shit

A Hare-Raising Night

In comparison to the hand-drawn sector of Toontown, the architecture and overall feeling of the scenery was less…loony. Most trees and inanimate objects lacked a face, and detailed textures matched up against the surfaces like a mosaic. Granted, in some places it wasn’t as bright and cheery as it was in the tree-singing, chaotic sector of the 2D Toons, but sufficed for most CGIs. At least one didn’t risk having an anvil dropped on their head, and the street signs stayed in their concrete foundations instead of scurrying out to cause the wayward tourist or visitor to get completely turned around. 

That wasn’t to say that Bruce didn’t enjoy the hand-drawn sector. The past decade had caused a rift of tension between the two mediums; a conflict similar to the black-and-white Toons, except perhaps more profound. Although CGIs were still Toons, their general make up was different along with their characteristics and usually less likely to be over-the-top crazy like most of the Toons in the hand-drawn sector. There were obviously exceptions to the rule on both sides, but the conflict mostly arose when CGIs started taking all of the jobs which would have otherwise gone to the hand-drawn Toons. Some people went as far as to call hand-drawn Toons outdated, and this fueled the ascending popularity of CGIs as a result.  

The giant shark shook his head, trying to clear his mind of worrying thoughts. Although the tensions was evidently present whenever he received a wary glance from a hand-drawn Toon- and not just because he was a shark- the shark was more or less comfortable with any Toons regardless of composition. One of the first Toons to actually lead him through the hand-drawn sector where he had previously never ventured too often was a special little Toon he had been so lucky to happen upon one late night out on the water. 

Granted, Roger had been more than terrified of the shark at first, and Bruce’s ‘playful’ taunting certainly didn’t help the situation too well, but after the great white revealed his true intentions and dropped his predatory facade, the two had surprisingly gotten close over the next couple of months. It might have been odd to see a small white rabbit hanging around with a twenty-foot long great white shark, but somehow they just clicked. Bruce managed to get Roger out of a few scraps, and the rabbit had no hesitation keeping a smile on the shark’s lips. 

And as the massive shark traveled through the transitional area between the CGI sector and hand-drawn sector, he was beginning to familiarize himself with the routes from Roger’s neighborhood to his own. 

After a few minutes of traveling along a dark street, the great white’s electroreceptors caught the sense of someone else. He slowed his pace, sniffing the air softly before pinpointing the direction of the footsteps. Was he being followed? Or perhaps there was just another Toon out and about at such a late hour?

Extreme Close-up - Great White Shark by georgeprobst This is the closest in-focus shot that I’ve ever managed to get a of a great white shark (Carcharodon carcharias). To give you an idea of how close this adult male was. This was shot at 17mm on a Canon APS-C sensor.

You can clearly see the shark’s ampullae de Lorenzini (electroreceptor sensory organs) and his blue iris.
