Hay, science side of Tumblr, or animal side of Tumblr, would any of you know if a bison/buffalo can survive cold weather climates? Such as mountainous places, or even places that have snow nine months of the year and rains the other three. (Gotta have my HTTYD reference, sorry.)
Would they be able to survive climates like the highland cow- wet and freezing, poor grazing type places?
What about other animals (specifically bovines other than yaks) that could survive cold climates like caribou/reindeer?
What about horse breeds? Just, domestic snow/cold climate-dwelling animals, I guess. I'm having trouble finding animals via the power of google. (for all bison/buffalo are considered 'domestic')

Seeing UV colors is common for butterflies, but in some species, it is a female-only power
Tumblr media
So, you may or may not know that many butterflies can actually see in UV light. It is very cool and I'm definitely not jealous that they get extra colors. It's helpful to them because many flowers have UV patterns on them (invisible to us) that let the butterflies know that they're a good source of food. The plants get pollinated and the butterflies get to eat. Everybody wins. This is a simulated version of what butterflies might see when they look at a flower.
Tumblr media
Some butterflies, such as the zebra longwing pictured above, only display this trait in females. Because of this, male and female butterflies will tend to visit different types of flowers. But scientists have just recently figured out how this difference came to be, evolutionarily speaking.
Obviously many species have sexually dimorphic traits, some more prominently than others. There are also cases in which one sex develops a trait that is just... less useful than the other, like this case with the UV vision. Almost all butterflies can see in the UV spectrum, so it follows that at some point in the evolutionary line the male zebra longwing butterflies lost that particular ability. There are multiple ways that this sort of thing can happen, and the article covers them briefly, but after sequencing the genome for these butterflies they found that none of those previously seen explanations were the case.
Basically, we already know the gene that causes UV vision in butterflies. It is called the opsin gene. In zebra longtail butterflies, this gene occurs on the chromosome W, which is the female sex chromosome. That means that sometime in history, this gene just jumped from a normal chromosome onto the female-only chromosome, and has locked the male butterflies out of this ability ever since. This is the first time we have seen a gene do a jump like that, and it is pretty cool.
But anyway, appreciate the girlpower of zebra longwing butterflies getting all the UV vision, and take a look at the study! It's free to read, which is really nice to see.

Laios Touden and autism; admiring the non-human
Tumblr media Tumblr media
Do you think people exaggerate when they scream about Laios being autistic? Do you feel like it’s weird that so many people including autistics are so set on Laios, the problematic (but incredible and kind) king TM, being the most autistic that has ever autisticed? Why do we cheer on autistic people wanting to be monsters?? Isn’t that weird?
Well, of course it depends on the way it’s done, it can be done quite offensively, but long story short Kui blew it out of the park. The thing is, autistic people really do like monsters and animals and robots. Nonhuman does not mean subhuman, it just means Other. Feeling a connection with them has been shown to be an extremely common autistic experience for that very reason.
Because some people don’t understand why we autistic Tumblr Laios stans cheer “autism! Autism!” whenever he talks about monsters and feeling alienated to humans so! Here’s a post about how yes even research papers are analyzing the special connection we form with animals. I’m not even joking but Laios Touden & the mass cries of relatability with autistic people he gets and all the love for him could be used as study material and evidence for future papers because the link is that strong. Oh also I think it’s notable that being autistic and undiagnosed vs diagnosed makes a huge difference. In my experience as someone who was undiagnosed up until 18, it’s even more alienating to not know that there’s a reason why you’re different, being gaslit that you’re ‘normal’ and you just need to try harder and get with the program, etc. Personally when getting diagnosed I went through the 5 stages of grief because the thought of having been fundamentally different all your life (a difference which you will never be able to change) and mistreated for it when you weren’t “wrong” all along makes you unload all the anger and sadness and loneliness and sheer trauma you’ve built up over time. Like it’s world shattering.
So! Back to seeing dogs as family. Also I implore you to value experiential evidence when it comes to autism and other neurodivergences because brains are complicated and neurotypicals not being able to understand us well even with scientific research is like, a whole thing even though we’re right there speaking about how we feel and being right every time because the topic is literally us and how we experience the world. 
Disclaimer for this whole post that, of course, no group is a monolith and everyone has different experiences or can diverge from the norm of the group, and that doesn’t diminish the validity of either side! Like, I know autistic people who have trauma with dogs and hate them. But, trends do happen, and in this case... Autism is very “My experiences with humans make me feel dehumanized in a bad and lonely way so instead I’ll dehumanize myself in a good and inspiring way”.
“I was treated like a failed human my entire life and you’re surprised that my response was to become a dog.” -Patricia Taxxon
It’s literally well recorded that autistic people relate to animals more than humans globally. With this post, besides spreading autistic Laios truthism and explaining why the portrayal hits so deep for so many,  I want to show in what way this is a very specific experience and not looking at his character through an autistic lense really misses a lot of why he’s everything that he is. (Tacking allegedly onto here for legal reasons, different interpretations are valid etc etc /gen). This honestly isn’t super long though.
To define an important term, anthropomorphism in the studies and in this post means to attribute human traits to the nonhuman, which not only includes anthro furry designs but also animals irl, inanimate objects, and animated media as opposed to live action, to humanize them and empathize with them.
Tumblr media
Paper: https://www.liebertpub.com/doi/10.1089/aut.2019.0027 
Tumblr media
“Dogs taught me how to hunt and socialize and work in groups”, Laios having internalized body language... So real so real. I, too, make a great dog impression. And I want to emphase the part that it helps greatly develop a sense of emotions and relationships! For Laios, he didn’t get along with kids his age, it was him, Falin and the dogs against the world. Since it’s a group of dogs too, it taught him group dynamics and social hierarchies (like with Falin being considered as being below the dogs in authority according to the dogs rip), and the importance of group coordination when hunting.
For me, I cannot like, concisely explain just how much animals were important to me developmentally. I also grew up with dogs, but like I vividly remember encounters with like hamsters as well just radically shaping my understanding of boundaries, the importance of giving something space and the way you interact with them and respect their side of it. Unlike humans they don’t really mask how they feel, it’s direct cause-effect reaction and data gathering. There are no words involved, so the focus on having a perfect phrasing and tone is gone, leaving just pure interactions. 
Tumblr media
There’s also no reason to mask how you feel either, and you don’t have to feel silly over wanting to form a connection and it showing, what, is the dog gonna laugh at you because you obviously want to make friends with it? Toshiro or Kabru might, but dogs and cats will just tell you to fuck off and leave it there worst case scenario. I often say that I think one reason Marcille is special to Laios and he feels comfortable around her is because she emotes INTENSELY, she gestures, she puts her whole body into it, her facial expressions are pretty exaggerated and her ears even emote too- like with a dog’s ears!
I think there’s def also things to be said about how he gravitated towards Izutsumi at first, all excited, was eager to sleep in the same bed as her, but in the Izutsumi sleep rating chart we see they really just casual and chill so it’s not a Laios talking to Shuro deep into the night situation just a “I like sleeping besides animals” situation and that is enough to hype him up. I love how he pet her in the extra about why Chil let her sleep with him too. He’s just so transparently eager to befriend her, even if in the end they weren’t all that compatible and he accepted that.
Tumblr media
There are honestly so many examples I could give for this. Like Grandin the famous cow lady.
Tumblr media
More about autism & empathy:
Tumblr media
https://www.spectrumnews.org/news/double-empathy-explained/ (Also mentions a study in which groups of autistic, allistic then a mixed group played a game of telephone and both singular groups had similar levels of information retention, but the mixed group was significantly worse. As an autistic person yeah duh, obviously autistic people are different from one another and can have plenty of interpersonal issues, but communicating with other neurodivergent people feels pretty intuitive and straightforward and comfortable. One of the reasons why neurodivergent people tend to naturally gravitate towards each other I suppose.) 
Tumblr media Tumblr media
^ Paper: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5932358/  For good, extensive summary of why we relate to animals so much you can go to the “anthromorphizing and asd” section of the paper. This paper extends to our widespread liking of cartoons and robots as well. Ok so this is a whole thing I won’t get into here but this is a big reason why a lot of autistic people are agender leaning as well. Genders and queerness in general is a lot about social constructs, and being queer is being marginal to these, not fitting into boxes or challenging those social norms and conventions. Queerplatonic relationships are a great example of this, where the framework of the relationship is platonic but the intangible nature of what it is exactly is the point, not familial not anything but everything at once too, just adoration, I like to say having pets is a bit like it as well, bc obvi it’s not romantic and often not fully familial, very platonic but also sooo much cuddling and adoration and kissing and whatnot that you wouldn’t typically do with a friend or family member. I’ll talk about qpr and labels another day though.
I got carried away but queerness in Dunmeshi is something I 100% want to make a big post on one day. Experiencing the world with different guidelines and not registering things to have the same boxes, sigh. Personally I also relate to Laios on a gender level, “cis by default because I don’t care all that much but if I were to dig deeper I’m probably otherkin and I want to be socially associated with traits of monsters and animalistic rather than man/woman” sighh hard to be a cryptid in this day and age. I wish we had a term like furry but for monsters, I want to be in the fantasy or folk tale genre ty, like changelings. Goshh changelings... You know, the irl myth where people said their neurodivergent kids were fairies’ children instead of human. Diminished physical sense of self means I see myself as some unknowable black  void aesthetic wise, but like in a way that simultaneously makes me feel seen. Like becoming a monster, losing your sense of self but also somehow just being simplified and seen for what you are, it’s weird to try and explain. This post is more about relating to the nonhuman than about seeing yourself as such, but like connect the dots right, that IS an important point of Laios’ character. It’s because our brains literally work different than allistics which makes us feel as other, but also because of social ostracization and functioning in a different way than society at large, living in the margin of society, being weird and non-conforming.
Meanwhile, animals and social norms... Like ok, showing your neck and rolling on the ground to show that you’re friendly and harmless and play biting might not be proper. But have you considered that it’s also fun and feels very intuitive. Play with a dog in the dog’s way I promise it is so nice and freeing. Play tug of war and growl back when they growl. Hiss at your cat to tell them they do something wrong, engage with them on their level.
Tumblr media
Autism made social life hard, but it made animals easy. Do you have anyyy idea how good it feels to mask all day every day and feel constantly misunderstood or like you’re doing a performance but then you can just, drop all of that in the company of animals and they understand you. They understand you. You form an understanding and rapport so easily.
And this whole thing with Laios is so explicit too, with the Winged Lion saying “You’re sick and tired of the human world”. Notice the choice of words. Sick and tired of the human world. Exhausted from the constraints, sick of the mind games. It really isn’t as much about loving monsters as it is about loving the nonhuman. Relating to them because you feel that you can actually understand how they work and think, and feeling like they could understand you back as well. Animals are safe.
Tumblr media
Like I could go on about how Laios admiring even just demi-humans like orcs is because they’re socially seen as non-humans more than any true physical thing, that they’re not bound by human society and its rules and live with their own lifestyle. But it would deal myself 1000 points of psychic damage and I am not ready to cry today. It’s idealization 100%, and like, Laios DOES want to be treated as human, to be valued, but it feels like an unreachable thing meanwhile becoming a monster is instant gratification and freedom and a sense that now no one will be able to hurt you in a way that reaches you, never again shall you be defenseless, and then if people dehumanize you then that only strengthens your sense of identity as a monster and UGHH ugh ugh.
And like. This post is a mess at this point but if you want to kinda delve into the more “why” then I recommend this Patricia Taxxon video essay. It starts out on a very different topic, but it’s all about autism and finding comfort in the inhuman. Long story short is othering made us like this also animals are just simpler to intuitively get along with.
So when I post this
Tumblr media
I mean it. I really mean it when I say he’s me. I have never felt so seen. So many conflicting emotions all wrapped so concisely yet so intangibly woven into the whole storyline so subtly. 
Not being depicted as a monster of an human being for feeling/having felt that way?? The manga understands you. The world can understand you. Other humans can understand you. You can bond with them. You can. And I think that’s a big part of Dungeon Meshi too- Laios opening up to others about how he really is and his interests, and all the bumps on the way but how it was the only way to truly get to know each other and bond. With the climax being Laios confronting head on his complex with monsters and humans, and his monster-loving side and animalistic side being exactly what saves the whole world, what saves humanity. Because Laios does value his friends, does think humanity has beautiful sides to it, he wants to help it thrive and eat and become more accepting, carving out a kingdom for misfits and demi-humans. At the end of it, transforming into a monster and being free is a daydream fantasy, and the reality of it is that Laios does belong in the world as he is, and does receive and give out love.
If you enjoyed this you’ll probably like some of my other Laios analysis!  Here’s an analysis of his succubus and what it says about his relationships with other humans. And here’s an analysis about his relationship with Shuro from his perspective.

Fun Fact: Starfish get around using a hydraulic system!
I want to start off by saying: you may have heard that starfish have sea water instead of blood! This is not true!
Before I explain, let me point out this little dot that every starfish has (and I SWEAR that this is relevant)
Tumblr media
(It’s like they all have lil’ buttons on! 1, 2, 3)
This little spot is known as a madreporite, from Italian madre (”mother”) + Latin poro (”pore”). 
What is it? Well, to over-simplify:
The madreporite is basically a pressure valve for the insides of the starfish. It lets water in and out of its water vascular system as needed. In order to prevent debris and sea life and other non-desirables from getting inside the starfish, the madreporite filters the water that it takes in.
this is what the madreporite looks like up close:
Tumblr media
(Name origin: apparently someone saw that and thought “huh, that kind of looks like madrepore coral, but tiny! They... weren’t wrong.)
Now, you may look at the name “water vascular system” and think “hey, I know ‘vascular’! That's related to blood!” This is a reasonable misunderstanding.
While in humans, the circulatory system is part of a vascular system (along with our lymphatic system) in the starfish’s water vascular system, seawater is NOT analogous to blood in a circulatory system. Or, well, it’s complicated, because it does do some things that are similar to a mammalian circulatory system, such as transporting certain types of immune cells, but still (source: Ferguson 1966)
Instead, these seawater-filled tubes are used for things such as the movement of starfish arms (and their little tube feet), which in turn allows them to move around their environment, find and consume food, and stick to surfaces. Mammals generally don’t use their circulatory systems in this way (if I am wrong about this, PLEASE let me know, as that would be absolutely WILD).
Tumblr media
(diagram of a starfish’s water-vascular system, revealing the starfish’s final form: some sort of fidget toy, I think)
I admit that “starfish use seawater instead of blood” is a much more attention-grabbing headline, but it’s not true, and it’s also kind of sad, because the water-vascular system is really cool without the misinformation!
(before you ask, yes, this entire post was prompted by one (1) person saying something that was WRONG, and that person may or may not have been related to me 😤😭😭😭😭😭)
The water-vascular system is, essentially, a hydraulic system. By adding and expelling water, as well as opening and closing internal channels via muscle contractions, starfish can create positive and negative pressure within their bodies. This allows them to “flex” their tube feet in surprisingly complex ways, among other functions.
Tumblr media
(these^ are a starfish’s “tube feet”. They are little structures with suckers on the ends. If you’ve ever held a starfish in your hands, you probably felt these feet holding onto you. They have a surprising amount of strength!)
You can imagine this sort of like how a whacky inflatable tube man uses air pressure to straighten up and fall down, except with hundreds in one connected, complex system (and also the pressure is more tightly controlled in order to prevent all that flailing, and also to allow fine control required for things like ripping open a mollusc shell).
Tumblr media
(I always imagine this when looking at starfish tube feet. And now, maybe you will too! join me. 1, 2)
The confusion regarding starfish blood being seawater is understandable, but in the end it’s essentially a misunderstanding.
Plus, starfish have coelomic fluid, which is honestly more analogous to blood.
Coelomic fluid is, basically, the fluid that fills the starfish’s body cavity between all of its organs and such, facilitating nutrient transport, gas exchange, and overall being more blood-like than the water-vascular system in general (Andradre et al. 2021).
And ok, technically the liquid part of coelomic fluid comes from seawater, ultimately, but that would be like saying I, a human, use tap water for blood. And, ok, yes, there is water in my blood, and that water came from the tap, but no one would say that I have tap water instead of blood! Except my brother but he also says trigonometry doesn’t exist so we will be ignoring his opinion at this time.
Tumblr media
(a more detailed diagram than the one before. The coelomic fluid is found in the coelomic cavity! Also, as a bonus, you now know where a starfish’s anus is! Enjoy this new knowledge next time you look at a starfish! source: x)
Starfish aren’t the only animals with a water vascular system and a madreporite. They can also be spotted in other echinoderms, such as sea urchins, sand dollars, and sea cucumbers (although in the sea cucumber the madreporite is inside the animal, so you probably won’t see it in the wild).
Tumblr media
That said, starfish have my favourite madraporites, because I think they look like little badges. They all win the award of being lil friends (and also keystone species that are essential to many marine ecosystems. So.)
This has been Fun Fact Friday, telling you all about wacky lil friends who have funny little feet and DO NOT HAVE SEAWATER INSTEAD OF BLOOD!
I will do battle with my sibling later, as is tradition

-It’s a small mammal that looks like a cross between a margay, a lemur, and a ferret
-super long body and neck, but short legs
-big dark eyes
-spotted, similar markings and colouration as a leopard
-if I remember correctly, the name was fairly long
Science/zoology side of Tumblr pleas help me
