In the universe of Star Trek, Vulcans and Romulans have green blood, while Andorians' blood is blue. And of course, we say that noble-born humans have blue blood.
In Star Trek VI: The Undiscovered Country, Klingon blood was portrayed as pink and lavender, while in Star Trek: The Next Generation and Star Trek: Deep Space Nine it was red.
A Vulcan's on-screen blood is green due to copper-based hemocyanin. Vulcans are said to possess an inner eyelid, or nictitating membrane, which protects their vision from bright light, an evolutionary trait developed due to the fictional planet Vulcan being so close to its sun.
His blood is a dark green, because Vulcan blood is copper-based, not iron-based. In reality, Spock's blood should be a blueish-black color, because hemocyanin turns that color when exposed to air, or to oxygen in the blood.
Andorians have blue blood, blue skin, white hair, and antennae on the crown of the skull. By the time of the 2001 – 2005 TV series Star Trek: Enterprise, the antennae were depicted as protruding from the forehead, and capable of movement, used for gesturing and balancing.

What color is ferengi blood?
Ferengi physiology is similar to that of their distant relatives, the Dopterians. Average life-span: 140-150 years. They have two lungs arranged vertically and ascending ribs. Their heart rate is faster than that of Humans and their blood is of a yellow color, but it turns dark blue-green when it oxidizes.
Dr. McCoy isn't just making up insults when he calls Spock "green-blooded." Like all great Star Trek Vulcans, Spock's blood is based on a copper binding agent, which gives it a green color when it's exposed to oxygen. (Human blood is iron-based, so it turns red.)
Biology. Andorians are well known for their blue blood, blue skin, white hair, and antennae on the crown of the skull. This blue hue of the species was the result of a high concentration of cobalt in the haemoglobin of their red corpuscles.
Grunts also have thick, bio-luminescent, light-blue blood, possibly a result of methane-based proteins in the blood to facilitate methane-based respiration. Like Earth's Horseshoe Crabs, it is possible that their blood is blue due to high copper content.
Turian blood has a dark blue colouration. Although life on Palaven is carbon-based and oxygen-breathing, it is built on dextro-amino acids. This places the turians in a distinct minority on the galactic stage; the quarians are the only other sapient dextro-protein race.
What is Spock's blood type as a Vulcan? In the episode “Journey to Babel” it was established that his blood type is “T-Negative”. He had to give his father a blood transfusion. At one point there was a Star Trek fan magazine called “T-Negative” in honor of this fact.
Although it makes a neat visual effect, and there were artistic and literary reasons for it (see trivia), the idea that Klingons have purple-pink blood is technically an inaccuracy within the Trek Universe. All other Trek movies and shows have consistently made clear that Klingons have red blood just like humans.
Yes, Romulans have a maximum life expectancy of 250 years, but the average appears to be 200 to 230 years. The same is true for Vulcans, with the average being about 220 years. Spock's father, Sarek, lived to be 202 years. A good deal longer than his half-Vulcan son, Spock, who only lived to be 162 years old.
No, Klingons were portrayed by a great variety of actors. There are dark-skinned Klingons and white-skinned Klingons. Gowron was played by a white man and Worf by a black man. It was the quality of the actor that was important.
Star Trek: Lower Decks season 4, episode 9 reveals that Klingons have pink blood, a departure from their usual red blood. The choice to give Klingons pink blood was made in Star Trek VI: The Undiscovered Country to create an alien look and to avoid a higher film rating.
Klingons possess eight-chambered hearts, two livers, multiple stomachs, an astounding twenty-three rib pairs, nictitating eyelid membranes, and three testicles.
Sangheili have at least two hearts, which circulate purple/indigo-colored blood through their veins; the coloration is most likely caused by bimetallic hemoglobin, possibly cobalt-iron, whereas the crimson-blooded Humans possess monometallic iron-based hemoglobin.
For example Master Chief has a blood type of O+ as he is a one-man army able to tackle every issue with a level head. Comparing this to the Rookie in Halo: Reach who is also O+. He was the last to survive in Noble Team and even transported Cortana himself.
They establish the notion of four sexes, as well as the rather complicated specifics of how Andorian reproduction occurs in 2003's Avatar: Book Two. The four sexes consist of two loosely defined "male" types known as chan and thaan, and two "female" types known as zhen and shen.
Andorians have 4 genders, 2 of which resemble males and 2 of which resemble females. These are called Thaan, Chan, Shen and Zhen. This can result in some confusion among outsiders. Sometimes it is difficult to tell what gender an Andorian is on sight.
Uhura's first name was not used in Star Trek canon until Abrams's 2009 film. The mystery regarding Uhura's first name is the subject of a running joke in the film, as Captain Kirk repeatedly tries to find out what it is, before finally hearing Spock call her "Nyota" in a moment of intimacy.
