I'm working on a story where there is a crime scene where the protagonist (who has a superhuman sense of smell) notices a scent that smells like human corpses due to their abilities. I'm wondering ...
I am designing a cold-blooded dragon about the size of a house cat with a wingspan of 3 metres from tip to tip. It will climb on top of rocks at noon when there is ample sunlight overhead. I need i...
First question so hope I'm doing this right! Working on a setting right now where a bio-engineered virus/plague is wiping out a large portion of humanity. Most died upon first exposure. Some surviv...
There's iridium-based blood called Chloro-carbonyl-bis(triphenylphosphine)-iridium that's effective at transporting hydrogen alongside oxygen. What I want to know is that, are there other metal-ba...
Some follow-up thoughts on this question... Hydrogen isn't very soluble in water. Oxygen is more so, but still sufficiently insoluble that most oxygen-breathing Earth creatures use special oxygen ...
A friend of mine has a race of creatures in her headworld and has been wondering about a biological answer to justify the color of her race's blood even though magic is a bit sprinkled in there. ...
Could a humanesque creature derive all its nutrients from drinking blood? One of the linked question's answers talks about the vampire becoming a filtration system from humans, could the vampire f...
So I want to have an alien creature on a planet with a halogen atmosphere. It will have to be at a temperature where the hydrogen halide is liquid or solid. This hydrogen halide I would have as th...
I'm designing an alien species, whose blood is highly acidic and can easily cause someone's hand to melt down. It's pretty similar to the Xenomorphs from Ridley Scott's Alien, except for the color ...
I am writing about a blood magic cult, and they drink/paint with collected blood to preform rituals and bursts of magic. Most of their supply is garnered through the use of human cattle, but in a p...
In my world I find it simplest to have iron-based blood. The problem is that iron-based blood is red, and I want it to be black. Two things come to mind; one is making the blood denser, resulting i...
Many people know that our blood is red because it is iron based. Many people also know that blood is blue or green if it is copper based. I'm wondering what color blood would be if it was let's say...
I wanted a creature that produces something in its blood to protect itself from SEP (solar energetic particles) and GCR (galactic cosmic rays). The skin of the creature is normally sufficient prote...
My heroine has been stabbed - run through the abdomen by a foot-long dagger - and is bleeding to death. She is currently crawling toward her salvation through a very cold place. She is magically ...
Can an organism have several types of oxygen carriers in its blood? Note that I am not asking how the creature could have evolved, that is too much sci-fy, genetically engineering or Deus Ex Mach...
I once saw an experiment with mice, where they connected the bloodstream of a younger mouse to the bloodstream of an older mouse. And the older mouse became "younger", or at least healthier. If I ...
In my story the inhabitants of Earth are near extinction. They want to make a capsule of a bunch of human DNA and blast it toward the Andromeda galaxy. They take 1 oz of every blood type still liv...
Ever since I found out about the green blooded skink, I have wondered if it's possible for other blood colours to evolve among vertebrates, specifically blue in mammals.
I have invented a large machine that allows me to create monsters out of blood. These monsters are called golems and are very powerful. My plan is to produce a large number of them to include in my...
What would be a valid reason for human blood/sweat/body fluids being toxic/harmful/caustic to an alien species' skin? What would the aliens' organic biochemistry be like and what would their DNA b...
I'm writing about a world that predates most modern forensic techniques, and I am looking for some old-fashioned methods of sleuthing that would have been available at around the 1850-1900. In on...
I am designing an alien civilization for a story, and I am currently in the biological part. They will be oxygen breathers, so they will need to have that oxygen delivered inside their bodies, and ...
I have a race of carnivorous mammals (the same from this question) for whom blood plays an extremely important role in cultural rituals. For complex cultural reasons, a member of this race (call hi...
I have done research on blood and in particular the component adding color and transferring oxygen. Hemocyanin is directly dissolved into the blood. This works for an octopus, but not a reptilian ...
Assuming that a vampire expends as much energy as a human of similar size how much blood would they need to consume a day? My naive estimate is 2500 calories a day, there are (apparently) about 9...
When looking at mammals and their heart rates one can find a correlation between the lifespan of a mammal and their heart rate. Namely most mammals seem to get about 1 billion (the American one) of...
Say they had pale skin, what would they look like? Would the lips be black? Would the vascular system show through the skin more? I'm not very interested in how or why their blood is black, just ho...
I have a race of people who have silver blood. Thing is, I'm really trying to keep it as realistic as possible despite this being a fantasy world. The blood has raw magic energy in it as well, but ...
Could a humanesque creature derive all its nutrients from drinking blood? Would a vampire get more energy, warmth or nutrients from fresh blood as opposed to frozen? What about fresh blood vs. old...
CODE DRIVER In my story, I want to have a world in the middle of a zombie apocalypse, but I also want it to feel different from any other interpretation out there. I call my monsters "Odd People" ...
So I want robot enemies in my series, but I also want gore without killing living creatures (related to this, because the opponent is the same, the gr8 computer) So basically the robots I talking ...
I've been working on an alien species, and I wanted it to have a blood colour other than red. I was going to go with Coboglobin until I found the sites I was looking at providing diametrically oppo...
Polycythemia is where the hematocrit is above 55%. This can be divided into absolute and relative and absolute can be further divided into primary and secondary. Absolute polycythemia is where the...
There have been a few questions on mobile plants on this site and even more on their intelligence, but one that has not been asked so far is related to the lifeblood of creatures: blood. Inside of ...
If your blood pressure ever falls below the ambient atmospheric pressure would it be possible for you to bleed. Because if blood pressure was less than that of atmosphere air would move in if you g...
So, according to Other blood colors it is entirely possible for other blood colours to evolve based on what base they use, but why? What would be the benefits of these different bases? What purpose...
We've all heard about a river of blood. But what would happen if we had an actual river of blood? Say a band of vampires creates a magical portal that draws blood from all the people in the area ...
If two different species with different blood bases, say iron and copper, had a child together, how would that affect their child? Which blood base would the child inherit? Could they even have a c...
How much blood does a vampire need? Could a humanesque creature derive all its nutrients from drinking blood? Both these questions have some good answers and my question is based off them both......
Other blood colors The link about talks about other color's of blood that could be if made with either different metals or different oxygen carrier's. What I want to know is if you mixed iron bloo...
Part of this story I'm writing involves a human subspecies who are adapted to extremely high altitudes -- as high or higher than our real world's Tibetan population, let's say. I've done research t...
