I wanna stop this misinformation being spread. Does anyone know how to report an incorrect google reverse image search result. This is not a shark named 'tasselled wobbegong", but is infact a misclassified goosefish/monkfish. https://t.co/l7pfPARDLP
A goosefish/monkfish appears to be be a subspecies of anglerfish, closely related to frogfish.While deceptively flat, it's important to also not confuse anglerfish with flounder. Brighter colored thing is actually the anglerfish species!https://t.co/UU7dTNrrYL
That video can be seen as a component of this larger collection exploring the frog fish https://t.co/2tSq76fQUL
It is also not a stargazer. They look similar when on the sea floor, but stargazers more classical fish shaped and really only appear flat because they bury themselves (instead of using camouflaged appendages like the anglerfish subspecies). https://t.co/d8kK3OSIeM
Interestingly, many stargazer and anglerfish varieties are able to use lures. The stargazer's is located in it's mouth. 😋I'm not sure if the original monkfish/goosefish imaged above has a lure.https://t.co/XJCbVUy8f4
It is possible that there are stargazers that use appendages. I am not a marine biologist, so I am not well versed in stargazer ambush tactics.This one apparently is Biofluorescent, and to my naïve eye looks patterned like a koi.https://t.co/wQLxEo1VxU
Biofluorescence is more common in fish than we previously thought, according to this 2014 post from the American Museum of Natural History.https://t.co/QflQW6Szl0
Today I learned that sharks also glow in the dark. The effect seems to be more visible if you use a lens that is adapted to a shark's vision. Also it is somehow antibacterial?!https://t.co/ijCPCYeSGp
Technically 'glow' is relative here. Fluorescence isn't quite the same thing as generating light (like firefiles), it's more a sort of remixing of UV (such as the moon).Language gets confusing quick. I am not sure if this is distinct from https://t.co/16EkQotsEi or a subtype.
Filter feeding shark has shiny teeth."white band denticles reflect wavelength in the entire visible spectrum, megamouth sharks could use the white band to reflect either downwelling light or luminescence produced by the plankton to attract and feed on it"https://t.co/hA03R2jNjr
Apparently my GF likes weird fish stuff.So now I'm learning about the varied morphology of shark eggs. Jawesome.https://t.co/EoVkItxouH
F****** mermaids, how do they work?https://t.co/X3M4EOlGmq
The shape of the horn shark is interesting. Looks like a fancy video game powerup.I wonder if the morphology of the egg has larger impacts on the morphology of the animal itself.https://t.co/FN3835wLcB
I thought sharks gave birth to live young, so this makes me wonder about echidnas.https://t.co/XkWNY2Ktgp
Apparently 'skates' also grow from 'mermaid purses' that look like shark eggs.So that means manta rays are closely related to sharks, neat! https://t.co/aybuK36aJ0
do sharks lay eggs?do sharks have dicks?do sharks fart?All vital questions for exploring the nature of an organism.https://t.co/tWtSFzJo0M
Yes, sharks have two dicks. Technically they aren't penises tho. They are called claspers.Nurse sharks apparently also like to bite during mate'ing.https://t.co/O8LC27tp1T
"Unlike a true penis, a shark's claspers aren't an independent appendage. They're actually extensions of the pelvic fins (the paired fins located on the shark's underside). Grooves within the claspers help channel semen where it needs to go."https://t.co/C8pmUcyMdB
Someone catalogued how big shark brains are. Horn shark has a huge brain compared to it's body mass (note: measuremetns are grams to kilograms)https://t.co/eW4Pzm6VF7 https://t.co/Lau5Gm2lNS
Apparently there are sometimes spurs involved with the claspers.Yeehaw.https://t.co/JN8zZTzIRR https://t.co/5NNSuAKLym
Have people experimented with this? Sounds like the kind of weird shit someone to try. :("Each shark has one anal fin, located under its body, near the tail. The anal fin helps to stop the shark from rolling sideways like a tube."https://t.co/8sKM3cXEwt
I'm imagining a bunch of baby sharks biting off fins like how axolotls nip at each other and one of them just suddenly barreling around like a tube and not giving a fuck.Baby shark, Do doo do doothttps://t.co/hodZ1vqWUy https://t.co/XX5gfYxZm5

Baby sharks, oh, oh, oh-oh, oh-oh"One reason for the "incredible shrinking shark" over the eons may be the process of neoteny -- the ability of some adult sharks to retain juvenile traits -- or their ability to achieve sexual maturity at earlier ages"https://t.co/amwzBfPzjp

"hey google, do why don't sharks have penis bones?"https://t.co/wWneY4v1Bx
Oooh neat. Rib development seems to stem from mutations from once being a fish.With the loss of spare ribshttps://t.co/kHgNBcsapCand the loss of rib bones in humanshttps://t.co/islIKuXdYfMight explain this strange mummy https://t.co/Ms4yMw04MC https://t.co/mFeGGFN36L
It sounds like they were doing genotyping. If its the same genes as the fish, we'd expect oddness in hox genes.https://t.co/DyvwuIVm0e
Tho this doesn't preclude bone development abnormalities from other processes. It seems gut bacteria can impact fly's hox genes. https://t.co/1omNQh2NjX https://t.co/md29HwzWjy
"Hox genes continue to be expressed in adult tissues and are misregulated in certain human cancers, but their functional roles in these adult contexts are not well understood," [Nov 18 2021]https://t.co/XhEKWe7zuT
Would be really funny if biblical stories about differences in rib counts was due to oddness in hox gene expression that has since been bread out of our gene pool.https://t.co/bcXD4AJm6v
Yet another hunch derived from ant-bacterial symbiosis as it interact with genetic expression."Carpenter ants need endosymbiotic bacteria to guide the early development of their embryos. New work has reconstructed how this deep partnership evolved."https://t.co/UgPQ5bds8M
It seems that we may be able to use oddness in hox genes within sharks to mine insights into the development of how "gnathostomes" (jawed vertebrates) evolved. Jawesome.https://t.co/SanbERzEz3
Why do they call them "elephant"?oh, they have big flappy "ears" and a trunk.https://t.co/EAKCmb8Kuo
Neat that they swim with their pectoral fins like a skate/ray and not undulating their tail like one would expect.Could they have also managed to get out of water like the tiktaalik?https://t.co/jsBcjouObR
"The graceful whale swims by undulating its wide tail up and down. And so does the shark, right?Wrong.Like other fish, sharks swim by moving their tails side to side. "https://t.co/c5hIxqh1NdALSO WRONG, lmao.
I hope some poindexter comes along and corrects me on the classification on the elephant shark."Well actually, they're not really sharks at all you see..."Listen buddy, they're named sharks. not "ratfish".Not my fault their slow to evolve.https://t.co/W44wKVcmlT
Next you'll be gatekeeping me about sturgeons.https://t.co/CxeuoB2EHX
Gonna invent a contrived classification scheme based on the number of hox gene clusters within the animal because at the moment I find that lens to be the most useful. By definition, the clustering method is defined by rolling a 5 sided die. https://t.co/3AEsC7D3sn
You can just make up classification schema. There's nothing stopping you. https://t.co/3BvIqCRQNf

Cold loving greenland shark lives a long time.Here's @hankgreen talking about nematode worm genes as being possibly related to why.(Also contains cool bit about Wobbegong lobes at the 5m58s mark.)https://t.co/yaX3ILfOIt https://t.co/9ifwdj6x3m
If sharks are fish, do you think they eat worms?It seems that research on cold tolerance among nematodes has been expanded to include C. Elegans related adaptations in this Sep 2021 paper.https://t.co/c9fpscK7sgYes, yes! Haha! sharks.https://t.co/jG7xyKIpde
I bet there's a direct link between cold sensing TRP receptors in cold tolerant wild C. Elegans and downstream impacts on metabolic function. It should also be mirrored in that long-aged shark, but perhaps via an ortholog/paralog/homolog.https://t.co/POM05ZxAQA

I find it strange that all my threads about evolution and limbs end up touching on about penis morphology. Its super annoying. https://t.co/EMjKqiCwks
Freudian jokes about penis envy bias aside. It seems one of the major reasons is simply that its easier to see phallic morphology over vaginal shape and function? https://t.co/QW9PLc8ilQ
So for my purposes, the egg seems to be a good proxy since it seems more commonly understood, widely used in the animal kingdom. We also focus on egg laying because it's used in chickens /ostriches as a foodstuff in industry, so there is a natural research bias in funding.
