THREE NEW SHARK SPECIES THIS WEEK!

The second week of July 2023 something extraordinarily beautiful happened, the findings of 3 new species of sharks for were announced

A new angel sharks species was identified, from the western Indian Ocean on the Mascarene Plateau and off southwestern India in 100–500 m depths, the Lea’s angel shark Squatina leae, was recognized to be different genetically and morphologically distinct from its congeneric species Squatina africanae, following unique morphological features.  This species was first detected in 1988 after finding  three unusual, small sharks, but till today was completely understood. The angel shark is named after one of the author’s fiancee’s late sister, Lea-Marie Cordt.

-  Squatina leae, adult male, in dorsolateral.

Angel sharks are “flatter sharks”, possesing distinctly broad, dorsoventrally flattened bodies, a short snout with large mouth and nostrils, eyes on top of the head close to the large spiracles, very large pectoral fins, and a lateral caudal keel. They've evolved to be ambush predators, they lie in wait for prey to pass closely overhead before attacking.

From North Australia, another species of hornshark is described based on six whole specimens and a single egg case. The painted hornshark Heterodontus marshallae was previously considered to be the same with the zebra bullhead shark another well know bullhead shark from the central Indo-Pacific from Japan  to Australia, but genetic and morphological analyses indicated the sharks were different, but looking alike. The painted hornshark is endemic to northwestern Australia and occurs in deeper waters, at 125–229 m below surface.

The painted hornsharks is named in honour of Dr. Lindsay Marshall www.stickfigurefish.com.au a scientific illustrator and elasmobranch scientist who expertly painted all the sharks and rays of the world for the Chondrichthyan Tree of Life Project.

And from an unidentified shark egg collected from the deep waters of northwestern Australia, in 2011 recently helped researchers identify a new species of deep water cat shark. Called ridged-egg catshark Apristurus ovicorrugatus after its eggs, it was collected in the earlys 90 but remained unknown to date. This sharks presents white eyes, and is small in size, reaching less than a half meter in length. .

Egg cases belonging to this species had been documented as early as the 1980s, but could not be matched to any species of Australian shark until recently scientists examined a shark specimen of previously uncertain identity in the CSIRO collection.

Sinobdella longitubulus, a new species of spiny eel (Pisces, Mastacembelidae) from the Zhu-Jiang Basin, with a note on the type locality of S. sinensis 

Peng Shan, Guangyu Li, E Zhang

Abstract

Background

The spiny eel genus Sinobdella belongs to the family Mastacembelidae of the order Synbranchiformes. Kottelat and Lim (1994) utilised Rhynchobdella sinensis as the type species to propose the genus. Currently, it contains a single species widespread in eastern and southern China and northern Vietnam.

New information

Sinobdella longitubulus, a new species of spiny eel, is here described from the Xi-Jiang of the Zhu-Jiang Basin in Guangxi Zhuang Autonomous Region, southern China. It differs from the single congeneric species S. sinensis in having a more or less white-brown reticulated pattern on the flank, two tubular anterior nostrils longer than or equal to the rostral appendage, an anal fin heavily mottled with dark brown markings and white spots and bearing a narrow white distal margin; shorter pre-anal length; and fewer abdominal vertebrae. The validity of this new species is corroborated by its monophyly recovered in a COI gene-based phylogenetic analysis and its significant sequence divergence with S. sinensis. A note on the type locality of S. sinensis is also given; its type specimen is possibly from mountain streams of Jiangxi Province, in the lower Chang-Jiang Basin.

Tagged by @bigfootsmom @iinryer for tidbit Tuesday! It’s late so I’m counting this double for wip Wednesday too, so here’s a kind of long bit! The opening of my big bang fic! OoOooOooh!

Eddie never knew anyone with the knack, growing up. Stacy Winters in the front office had it, according to playground rumor; she and her husband, who was a ranch hand or a cop or a power line worker. Eddie's mom shushed him when he asked about it and told him not to listen to gossip, and anyway he saw them dancing after school once and they seemed just like anybody. He twirled her around and around and she laughed loud enough for Eddie to hear her way down the hall where he was sitting in the nurse's office with an ice pack over a bee sting, watching through the open door. His abuelo and abuela danced like that, and sometimes his mom and dad, too.

It’s a rare phenomenon, a teacher droned on in sophomore biology on a day too nice outside to pay much attention to anything. Congeneric minds — or any of the dozens of colloquial names for them — are uncommon enough on their own, and the odds get even longer for them to find someone who also has the knack that they actually click with. Abuela called them lost pieces, like when Sophia had bumped into the dining room table and sent the jigsaw puzzle flying, sending parts under the fridge never to be found again, leaving their matching edges forever lonely. Together, congeneric minds are capable of great feats, the teacher went on. They share instincts, feelings, sometimes even movements, one mind sending a signal and another body responding. Little is known about the science of it, though not for lack of trying. There’d been a bunch of papers about experiments to force the pairing to happen in people, and then decades later a bunch more papers about how that doesn’t really work, and is entirely unethical anyway. Adrenaline seems to figure into things, some evolutionary quirk to give people in dangerous situations the best chance at surviving.

Perhaps unsurprisingly, people with congeneric potential tend to flock to high stakes environments. Eddie finally met a few pairs in the army, folks so in tune that one of them would be in the air before the other said jump. He’d found it a little uncanny. Johnson and Tucker, eating in the canteen, movements so synchronized it looked like they shared one body that by some bureaucratic error had been spread across two people.

He saw Tucker die, a few months into that first tour. Watched Johnson scream and choke and claw at his chest like the bullets had torn through him. Thought, guiltily, that he was glad no one knew him quite that well, shared his life quite that entirely.

And then, in Los Angeles, 2018, Eddie had met Buck. Then, huddled over a man with a bomb in his leg, Eddie had needed gauze and Buck’s hand had moved. Then, in the parking lot bathed in the light of an ambulance on fire, Buck had inhaled and Eddie's lungs expanded. And, well, that was that.

I just found out something super cool that I have to share with you all.

This is a bush tomato species, discovered ~7 years ago.

Pretty, isn't it? Its name is Solanum Watneyi, after one (1) interplanetary botanist. It's related to the potatoes grown on Mars (Solanum Tuberosum), and it grows in red dirt (almost like the surface of Mars, huh?) Here's a quote from a research paper (Martine, et al):

Etymology

The specific epithet of "watneyi" is inspired by the book and film, The Martian, in which the protagonist finds himself stranded on Mars surrounded by the planet's harsh terrain and reddish soils. In a shelter, he manages to grow a crop of potatoes (Solanum tuberosum) before finally being rescued by his astronaut colleagues. We've chosen to name Solanum watneyi after this character, Mark Watney, in part because of the similarly reddish soils of its habitat and the congeneric nature of the potato-but, most notably, as a way to honor the creation of a sci-fi hero botanist by author Andy Weir (Weir 2013) and to acknowledge perhaps the finest paean to botanical science (and botanical field work) that Hollywood has yet presented (see Martine 2015).

Anyway, I just love when scientists pay homage to fictional events. Life imitates art!

What is the Meaning of this Exercise. A Follow-up to “The Students”.

What is the goal of this communication? I was joking with a correspondent that it was to make myself “uncancellable” and thus free to express because the symbols that I use are not immediately recognisable to the native Anglophone reader; I will be content with a half-a-second advantage before the verdict, which is already more than is granted to those who use the fashionable vocabulary. That is to say… You are free to cancel me, but first understand that you disagree with me.

But speaking more genuinely, my goal is to express the reality I experience through forms that are more recognisable to myself, who always felt more comfortable with the meanings expressed in books than the live-spoken words of my congenerates. Book words were composed by humans too, but these are the practised words, especially before the keyboard age. The word is the drawing of the word sound and in the span of its conjuring there is time enough to contemplate. How would my thinking be different if I had first learned to write in pictograms? Many of them are written in fewer strokes, and so, with more speed, I could imagine and be wrong completely, and each of them encompasses a meaning.

What does this composition read like, in my imagination? A translation from another language. Someone writes for a subscription in the backwaters of X, regurgitating misrepresentations of the writings of a mysterious group of people called the “Europeans,” who may as well not exist, or if so be on the same plane of unreality as Sokrates, known only from the words of others. But what is less real than this but life, which is what happens in the background. It is shameful, again, to say “Something must be done!” The same question without resolution for the interminable centuries. Meanwhile the country, and by this I mean the physical place that you can touch with your own hands and measure, is falling to rust and unswept red brick dust. None of our problems are unique, though the nationalists would lie to you that they are. How they hate to hear that the same thing, more or less, is happening somewhere else! Other places have their names for the Republic of Indians and the Republic of Spaniards, and whenever a writer mentions the phrase “Andean idiosyncrasies” or what makes me spit up in anger, the butchered New Age “cosmovision” to explain serfdom or state corruption it is as meaningless as when someone were to say, for example, communism or capitalism with Chinese characteristics. There are social and economic reasons, not some unique quality of the soul. That is what we tell foreigners when there is something that we want to sell to you.

As an aside, at a certain time, these two regions did experience a similar search for identity, or rather an attempt to create one. For lack of knowledge of the one I will not comment as to the success of either case. Only to say that I prefer the idea of the community as a group of people that interact to form a relationship with one another, rather than the community that is predicated on a collection of traits that serve to unite the group at the exclusion of others. These definitions coexist and each serves its purpose in describing social phenomena, but the reason to document our reality should be to use put this information to use, and make a choice about what we actually would like to see.

It is easier for me to think when I write; this is an exercise to make myself more aware of the impressions that I collect, and I do not expect it to be of use to anyone else, except to receive a clearer image of another human filtered as it is through an affectation of style (unnecessary) and a degree of self-censorship (necessary to survival). As for this style, so long as the rest of the world continues to drag around the corpse of the 19th century and novel pathogens continue to ripen from the same old source I will continue to reflect this in my sorry compositions.

Goodbye, until the next time. And goodbye, until the next time.

JMSE, Vol. 12, Pages 1427: Complete Mitogenomes of Deep-Sea Eels Histiobranchus bathybius and Simenchelys parasitica and a New Record of H. bathybius from the East Mariana Basin, Western Pacific Ocean

In this study, using Illumina sequencing, we sequenced first the complete mitochondrial genome (mitogenome) of two deep-sea eels, Histiobranchus bathybius and Simenchelys parasitica, collected from the East Mariana Basin in the Western Pacific Ocean. The complete length of the H. bathybius and S. parasitica mitogenomes were 16,696 and 16,687 bp, respectively, each containing 37 genes (13 protein-coding genes, 22 #tRNA genes, and 2 ribosomal #RNA genes). To enhance the accuracy of the identification of H. bathybius and S. parasitica, we performed a phylogenetic analysis of multiple deep-sea eels based on the mitochondrial DNA gene (cytochrome c oxidase subunit I [COI]) using the maximum likelihood method. Our phylogenetic tree analysis confirmed that the specimens collected in this study are congeneric species of H. bathybius and S. parasitica reported in previous studies. Based on these results, we report the first complete mitogenomes of H. bathybius and S. parasitica and a new record for the two species in the East Mariana Basin. https://www.mdpi.com/2077-1312/12/8/1427?utm_source=dlvr.it&utm_medium=tumblr

wip game: should we talk about the weather 👀

Hehehehehehe big bang fic!!! Hmm I’ll share the pitch I gave to the event artists (hehehe…)

In a world where certain individuals are capable of sharing their own instincts and feelings — and even occasionally physical strength — with their likewise capable partners, Eddie and Buck, and Hen and Chim are what people sometimes call congeneric minds. It comes in handy in a high stakes profession like firefighting to have two people in such synchronization, able to warn each other of danger without ever having to waste time opening their mouths to speak.

Being so in sync with someone doesn’t necessarily mean smooth sailing communication however. Recently back at work after taking time off post-shooting, Eddie worries about Buck and how he’s been dealing with the events of the last year (last several years, really) but doesn’t know how to bring it up when he himself has always kind of encouraged them to move past life changing events with little discussion. While Hen and Chim are getting along just fine, Chimney and Maddie are dancing around each other and their recent breakup, and Hen feels trapped between disappointing her mother or her wife while being roped into backyard wedding planning.

With danger ever present on the job and turmoil seemingly always bubbling outside it, will everyone find the right words before it’s too late?

AKA what if people could be drift compatible in regular life without giant robots, and they’re all disasters at communicating anyway

And here’s a snippet!

Eddie doesn’t get around to talking to Buck till a week later. They’re in Eddie’s house again, but Buck has started to look exhausted everywhere, all the time, nothing special anymore about the way his eyelids droop when he walks in through this specific door. It’s worse than usual today. They had a hell of a long call — a rockslide down on the PCH, outside of their usual range but it was bad enough that the responding station had called for any back up they could possibly get — and Eddie’s wrist and shoulders and whole damn body aches from the hours of grueling work. Buck has to be feeling it, too. Eddie heads right to the bathroom, grabbing the tube of arnica gel that keeps this household running some days.

He doesn’t know how to bring anything up. We need to talk feels as ridiculous as it does dire. That’s a movie script confrontation, as contrived and meaningless as it’s not you, it’s me, or I’m sorry for your loss. Buck is his best friend, and also their fucking hearts beat in rhythm. He can do better.

“My leg hurts sometimes,” is what ends up coming out of his mouth when he gets back to the living room. Your ache is mine. A little poetic, but whatever. It gets the point across. Share it with me, please. We already do, so why are you hiding it?

Buck is sprawled on the floor next to the couch, Eddie isn’t sure why. He looks up at him silently for a few moments, and then rubs at his shoulder. Answer enough. Eddie barely has to look as he tosses him the gel, sure Buck will catch it as Eddie sits on the couch with a sigh. He watches Buck, still prone, hike up his pant leg and start massaging arnica into his calf muscles.

“Are you… doing okay?” It feels stupid to say.

Buck looks at him like it’s stupid to hear, too. His fingers drum a few times over one of the jagged lines still drawn up his shin. “‘M fine, Eds. Just a long day.”

Eddie purses his lips, shaking his head back and forth in a slow roll against the back of the couch. “You know that’s not what I meant.” His hand lifts up to catch the tossed arnica without thinking about it. He looks down at Buck, sprawled out, looking back up at him. “I want to… know that you’re okay. And, Buck, I’m here if you’re not.”

Buck sits up with a sigh that’s more petulant and annoyed than Eddie wishes it was. He rests his chin on his bent knee. “I know. But I’m- I’ll be fine. Stop worrying.”

Eddie snorts at that. “Oh, yeah, that’s something I’m great at.”

Buck’s smile grows so tenderly across his face. “I know.” He twitches his right pointer finger three times and Eddie’s moves involuntarily with he tug. “Come on,” he says, standing up with a groan. “Let’s make the pizza.”

They’d bought the ingredients together — sort of together, Buck on the phone at the grocery store and Eddie and Chris shouting requests down the line — earlier that week, and Chris will be home soon from a friend’s house and likely starving from the hard work of being a twelve year old all day long. He’s old enough that the novelty of making the pizza himself is less appealing than being able to immediately eat it, even if Buck had made sad faces as he’d relayed his instructions to make it in his absence. And this is all a distraction, Eddie knows it is, but Buck is smiling down at him and his finger goes tug, tug, tug, and he lets him get away with it.

The genus Brachygobius is a nexus of species in the true goby clade, that are collectively known as bumblebee fishes or bumblebee gobies, in account of their colours and patterning. Often they are seen in dealers aquariums, because they are petite and beautifully colored. Yet much confusion exists as to which exact species is being traded, and what water conditions they might benefit most from, or are natural to the wild gobies. Particularly, the question of proper salinity, with confusion and dubious, repeated 'facts' as to their wild habitats.

B. doriae, B. nunus, and B. xanthozonus in particular, are often confused, and indeed, there is confusion even among ichthyologists, as to which of the Brachygobius species an individual bumblebee fish, or Its population, might belong to. The species of Brachygobius are, in nature, partially separated by environmental niche partitioning, with some species present in wild freshwaters. However, the Brachygobius sp. most usually encountered in the aquarium trade, are in fact from brackish waters.

For instance, B. doriae is sympathetic with Rhizophora mangroves, as well as fish like mudskippers, siganids, and archerfishes, in the muddy lower (and thus tidal) reaches of tropical Asian rivers. Thus this species, chosen as an example, would appreciate a quite higher brackish salinity, than books might suggest. But also, it's presence overlaps with that of the palm, Nypa, which is not as salt tolerant as is Rhizophora, so it would be wrong to reckon B. course as a marine fish.

Smaller Brachygobius species, such as B nunus, might grow to around 1 inch or 2.5 centimetres long. Larger congeneric species of bumblebee fishes, can grow to about 4 centimeters, or over 1 and a 1/2 inches. The small size of these beauties has often appealed to those seeking oddballs or brackish fishes, but finding themself with limited space. Although the male gobies can be territorial to one another, its possible and imperative to house members of these species, in a group of about six or more fishes. Single fishes are too easily stressed, it seems. A combination of factors makes these fish unsuitable for a typical community tank, although with careful thought, they can share with other benign brackish fishes.

Its also worth noting that these gobies appreciate it demand warm end tropical temperatures, higher than the 24 degrees centigrade standard, that is probably the norm for tropical tanks. Perhaps a temperature between 25 and 28 degrees centigrade would be ideal for their aquarium. The wild gobies show a positive association, with a muddy substrate. Again contrary to information in books, these gobies do not need crystal clear water, as they evolved in conditions of turbidity. Their presence in mangrove habitat, means that non-toxic leaf litter and wood, are suitable choices for the aquascape also. Wood could be arranged to imitate the appearance of mangrove roots.

Brachygobius sp. aren't quite as finnicky about eating, as some aquarium literature might lead you to believe. These gobies will, at least if acclimatised, take to defrosted foods, and do not require regular feedings, of love invertebrate prey. Some of them even adjust to nipping proprietary flake foods, although it must be cautioned, most of them will not accept manufactured substitute diets. Given that misinformation about feeding this genus, has daunted many aquarists from attempting bumblebee fishes in the aquarium, it isn't really a basis for most fishkeepers to fret unduly about. Misunderstood fishes that are not eating, are presumably stressed in some way.
