Have this hoofed biped with pale nearly furless skin with a bit of thick blubberyness. I imagine a bit like some of our sea mammals. Green blood can be seen somewhat through the skin. Around human sized. Legs are human-like. Have 3 hoofed toes on each foot- 2 in front and 1 in back. Hoofed fingers. Horse-like head. Herbivorous. Very polite with very many social rituals; we would probably see them as excessive.

What might this creature's environment be like to give them these traits? What things would make a society very polite and full of so many social rituals? (I figured environmental factors would factor into culture behavior somewhat, like my world where it was essential for groups to work together quickly and effectively to fight off large predators and other threats, resulting in their suspicious nature and common mob mentalities)

I figure that their world could be almost constantly overcast, for their skin to be pale.

    $\begingroup$ The medieval Chinese high society was famously very polite and full of intricate social conventions. It was also contemporary with the very much less polite Mongol society. Which goes to show that politeness and social ritual is not a characteristic of the species. You are mixing up biology and sociology, and this is a severe category error. $\endgroup$ – AlexP Oct 11 at 22:18

Green blood implies copper based blood. This could happen but copper is not as good at binding oxygen as iron and is not quite as common.

Octopi have copper based blood and they get exhausted quickly since their blood does not hold as much oxygen. So, your creatures would be great bursters/sprinters but would suck at endurance.

I would give their world a higher oxygen content then Earth just to help them out a bit.

The legs are a bit problematic. If you don't mind them having "backward knees" like most 4 legged creatures, it is easy to justify them needing to reach up and grab food or manipulate things to get a food (leading to hands and, eventually upright posture).

Hooves and backward knees are both enhancements to make running and jumping more efficient. If their ancestors weren't good at running, you have to figure out how they survived long enough to develop hands.

Human knees came from tree climbers and I don't see hooves being good at climbing trees.

The rest is just cultural and can be extrapolated from herd behavior.

    $\begingroup$ I've seen the article here about leg type pros and cons, but I guess I'm still having some trouble determining which would be best for different creature's circumstances. I guess I'll need to do a little design change. $\endgroup$ – Chickenpeep Chickenpeep Oct 11 at 23:41
  • $\begingroup$ @ChickenpeepChickenpeep, just think of what would be the best leg design for whatever they were before they were bipedal. $\endgroup$ – ShadoCat Oct 12 at 0:50

Adding to ShadoCat's excellent answer since I have no justification for green blood...

It is believed that hooves evolved to help handle increasing body mass in plains herbivores but they have also proven useful to creatures living in high jagged terrain (mountain goats). So your bipeds will have plains or mountain dewellers in their evolutionary history. Their being herbivores favors the plains history, but the segmented (cloven) hooves favor the mountains. So maybe include both.

The hoove-ed fingers suggest that bipedal may be a recent and possibly incomplete evolutionary improvement.

Looking to human evolution to justify your biped's fur-less skin, you can choose one of three prevailing theories...

1). They have an recent aquatic mammalian ancestor.

2). They lost the hair to keep from overheating in their extremely hot Savannah style territories.

3). They lost their fur to discourage fatal pest infestations.

    $\begingroup$ In the dream the creature originated from, I remember pale skin, so I made their planet primarily overcast so they wouldn't sunburn, so it might be a bit chilly, so I imagine them to be slightly blubbery like a seal, so the first one sounds the most likely. $\endgroup$ – Chickenpeep Chickenpeep Oct 11 at 23:46

    $\begingroup$ Rock climbing could have lead to hands if they needed to get to harder to reach places and needed to grip and pull themselves up or if they needed to grab food just higher than they could reach through climbing. $\endgroup$ – ShadoCat Oct 12 at 0:51

Let's review the traits individually.

Green Blood

As ShadoCat said it does tend to imply a copped based blood, but a number of iron based compounds are different colors. Ferroferricyanide is better known as Prussian Blue. Jaundice is caused by a build up of bilirubin in the blood. Methemoglobinemia is a disease where hemoglobin is replace by methemoglobin. It is responsible for the Blue Fugates of Kentuck. A combination of slightly unusual blood chemistry will result in mostly normal people/creatures with green blood.

There are adaptation penalties with these defects but they are survivable, and if there is an evolutionary benefit (like protection against malaria that comes with sickle cell anemia) it might be a common trait. It could even be the result of a founder effect.


Small hard feet are common animals that browse and graze, things that spend a lot of time wandering around on fairly hard surfaces eating low nutrition.


This tends to occur in a few situations. Aquatic animals (Cetaceans, Sirenia) and Thick skinned animals (Pachyderms, Armadillos). There are edge cases which once again focus on founder effects and parasitism.


This is fairly rare. Humans of course, Kangaroos and the like, as well as some birds. There are some quadrupeds that occasionally adopt a bipedal stance to reach higher leaves.

Looking at real animals we have some which tick a lot of the boxes.

Gerenuk: semi-bipedal, hooves Swine: Hairless, hooves Humans: Hairless, Bipedal Hippos: Hairless, semi-hoofed Ostrich: Bipedal

Probably the best course for evolution would be something in a forest that changed over time from something dense allowing for the loss of hair that then shifted to a more savannah environment where it was necessary to forage from the leaves of trees.

Parasitism or a founder effect could cover the green blood.


Green Blood

Green blood can be seen somewhat through the skin

That doesn't mean they HAVE green blood, however. I have red blood when you cut me open, but the veins you CAN see under my pale-as-heck skin--those are blue, NOT red.

Contrary to popular belief, blood is always red, even if it hasn't been oxygenated.

So why can blue blood be somewhat seen through the skin on pale people?

It's an optical illusion.

Sometimes blood can look blue through our skin. Maybe you've heard that blood is blue in our veins because when headed back to the lungs, it lacks oxygen. But this is wrong; human blood is never blue. The bluish color of veins is only an optical illusion. Blue light does not penetrate as far into tissue as red light. If the blood vessel is sufficiently deep, your eyes see more blue than red reflected light due to the blood's partial absorption of red wavelengths. SOURCE

Stuff that's really close to the surface in the capillaries still look red (which is why lips are a ruddy color).

My point here is that you can have the effect of them looking green, or their blood looking green when it is inside them without their blood actually BEING green. All you have to do is add yellow to their skin structure. Not a pigment, the actual structure. And even then, they STILL might have pinkish "lips" or whatever.

So they might look unusual and colloquially they might refer to their green blood (which if they are herbivores makes sense), kind of like how we talk about blue bloods. An outsider might actually believe that they have green blood inside, because it's talked about and they have a "green cast" (ie. deep vessels that can be easily seen with more frequency than human vessels through yellowish skin) when in truth, they are just as red-blooded as we are.

Bad weather Those who are suggesting a higher oxygen level on your planet to allow for the blood to actually be green, there are theoretical models for that They use OUR planet as the model so YMMV. Basically more oxygen = less rain. So you're going to have to come up with another reason for it, or rebuild the atmosphere in a different way.

Planet of the ? While we are on the subject--an entire planet with one atmospheric condition is a big trope. And for a planet that sustains life on a complex level? Very strange indeed. Humans are versatile, but where we came from informs what we are like--we walk because we needed to see predators in the grass. Your folks might prefer gloom and wet to sunshine and settle in places that have that, but the whole planet being one particular way, is a stretch.

I think this stack exchange link will be useful to you: Why does my species tock like it ticks?

Overly polite? Always working together? You already got us Filipinos. At least how people think of us are. Then you go to our country, then you see it's not exactly how you thought it'd be. If you're white you'll be treated as you are by them in the West -- very well. If you're not white, then not so well. Always be careful with theft & being scammed, btw (my personal family & friends & so does some official Travel Advisory says so).

Always cooperating? In a chinese or some other Asian manner? With rituals full of meaningful & kind gestures? No, that's why we have a thing called "crab mentality", not mob mentality. It means if someone gets a little bit ahead, you'll get dragged down. It more broadly applies to if you stand out, then you get dragged by the rest to where they are. Now that's some kind of Asian for you.

If with, mob mentality, you're talking about riots & protests, I wouldn't call it that. It's an easy way to vent out the hardship of poverty that they just can't get away from. It's the same why at noon, so many people are glued to watching mixed variety shows. Why? Because it has a lot of contests where ordinary people win a sizable amount of money. Call it placing themselves in that position, but they love watching those.

Filipinos ARE cautious & afraid of new things. My Mom is sorta like that... And, my Dad too.

What, you thought the Philippines is like that movie Trolls? Always so happy? Like what you see when you peer into our (not so) little parties? Singing, laughing & always getting along? It's VERY HARD to explain to other people, but we're like that because things are just doing just fine living a middle class life & nobody's doing better than the other people in the party. Maybe it's the immigrant spirit of competition, but you see the same thing in the Philippines. Do not hash together my need for rituals, with that false image in your head of Filipinos of these small-framed, sun-tanned (1) tropical island folks, always looking for an excuse to help a neighbor, say to thatch that hut's nipa roof.

Let me paint a picture how it looks like in the Philippines after straying from the beaten path of tourists, or have the unfortunate luck of experiencing it early. You'd see the people love their music, that's fine... Then there's a lot of shouting, bickering... Though, it's not the cultural sweet teasing Filipinos would engage, according to some people that have hanged around us. The shouting goes along the lines of "Hey! You're two months overdue! Pay up!". That's comical, might actually make it to a movie. "Junior!! Come here & fetch your sorry drunk of father drinking at the corner store again! Putang ina, won't get a job!" or "Hey! That addict brother-in-law of yours scammed me! Ask him to show his face to me!", etc, etc. These things I mention are actually still light. You can see that the morality of the urban society is quite low & there's a lot of crime.

We're not even super "LOVEY DOVEY" in general. A Filipino can show that affection to another family member, but not to strangers, not even to neighbors. It's this black & white polarization in Westerners minds, "Oh, they're good & polite, that means everything else is pleasant & good. Oh, they seem bad, that means they're no good at all."

To the OP, even bigger reveal? We don't even have intricate social customs that adhere, not like other Asians. We just kinda roll that way. If it's fiesta, then it's fiesta & you can expect the same show. Nobody's gonna be too picky with the details, though (another thing I diverge from my base culture).

So, I won't even put Filipinos as this could've been, of how societies around the world could be, centered on helping each other out (without feeling excessively jealous), being VERY POLITE & PLEASANT (2) & in an almost primitive way, having no ill-will at all. As Sherry would think of it?

Another thing about me that pairs well with what people think of Filipinos is that I'm very nice & kind, according to them. One of the reasons being, is because I let people be. That's already unusual among Asians. With Asians, if you're different you get hammered back to your place; who do you think you are? A bit different? Something is deeply wrong with you. Me? I faced adversity growing up. The fact that I wasn't with the boys that wore hair gel in "Oasis" (as in the band) fashion nor was I totally into basketball, already set me up as "not one of the guys". So I had a more lax tolerance of people. Getting here to Canada, immersed with so many cultures only but reinforced that view. When I was in Burnaby South HS, back in it's heyday when Per ruined place, that was the feeling. Then I got to SFU & it wasn't the case anymore.

I don't push people into my taste or standards. Though I hold a standard to my own. Not anything would "just do", despite what people expect Filipinos to settle on. There are right things & wrong things to do. If you're not, as a consequence, hurting people (i.e. doing illegal things), then live your life the way you want & I won't obstruct you. I may not have a good opinion of you & I might let it slip (3). But, sure, live you life. You can say what you want & express yourself, I won't stop you. But, in the same token, I expect you to let me respond & have my expression, such as when I call out that I think what you just stated is stupid. See, in my head, I'm trying to draft a sort of social contract of etiquettes, though I've already been beaten to it. You guys now understand that, right? I'm looking mostly at you, you classy vancouerites & kongers. I've explained this all in one of my balcony speeches, but alas, nobody was listening & those that were retained extremely little.


(1) Alright, I'll admit, many of us back there are small-framed & sun-tanned.

(2) Sherry, I was really down on the dumps. I've hit rock bottom & being driven away from the University (I wasn't hallucinating it). I needed support. Fcking ridiculous. How could you think yourself as being a great & well seasoned social worker, if you can't even identify that being the reason I was SO POLITE & PLEASANT. You just say a lot of opinions about your cases to the psychiatrist & that makes you look like having a good alternate point of view. Point of view that reassures & makes you feel good, sometimes even based on your projections. Sure was enough to get you ahead professionally, wasn't it?

(3) You can ask people about when I was younger & they'd say I can be tactless about people. It's a not a recent re-invention I made a few months ago about me.

As you guys see, my writing is a bit idiot-proof. That's because this will be read by a lot of vancovuerites. A lot of fcking idiots.
