Vulcans are not supposed to drink alcohol, although they are often portrayed as such. In an episode of Star Trek: Deep Space Nine, Quark alludes to Vulcans getting drunk from ingesting chocolate. An episode of Star Trek: Voyager mentions that volcanic coffee is poisonous to humans.
Due to their sensitivity to sucrose, however, Vulcan’s have a sensitivity to chocolate that mimics the kind of dizziness a typical human would get from being too casual about a traditional celebratory drink. In short, regular chocolate can get Vulcan sloppy real quick.
We know that Vulcan blood is copper based instead of iron like humans, which makes it appear green instead of red. This is evident in bruises or bleeding, as well as in Bones’ insults to Spock.
Vulcans usually mate whenever they want to. But every seven years you do the ritual, the ceremony, the whole thing. The biological urge. You have to, but any other time, every other emotion – humanoid emotion – is when you’re in love.
Vulcans are strong due in part to the surface gravity of their homeworld, but the Romulans left that homeworld two millennia ago. If Romulus had a surface gravity of one g, the numerous Romulan generations would have adapted to it over time. So set the Romulans to the same human strength.
If the Vulcan menstrual cycle has a different duration, it may only affect the number of fertile days per cycle. You may only have it every seven years.
Emotions. Vulcans are known to be logical beings who have removed emotion from their daily lives. The Vulcan character Spock struggles with this throughout the original series as he is half-human. T’Pol says that before Surak’s Code of Emotional Control was instituted, paranoia and murderous rage were rampant with Vulkan…
Sulfhemoglobinemia is a rare condition in which there is excess sulfhemoglobin (SulfHb) in the blood. The pigment is a greenish derivative of hemoglobin that cannot be converted back into normal, functional hemoglobin. It causes cyanosis even at low blood levels.
The alleged reason for this is that having red blood floating all over the ship was considered too violent and would have given the film a more extreme rating than the target audience deserved. Pink Blood makes it clear at a glance that the violence is simulated and not real.
As we (and by we I mean fans of the original series) can all remember, one of Leonard McCoy’s nicknames for Spock was “old Pointy Ears”. These pointed ears allow Vulcans better hearing. Because of this, Vulcans have better hearing than humans.
The Vulcan finger touch was a ritual gesture among the Vulcans using the index and middle fingers. It has been used throughout their culture, including in public as a greeting or to signify affection, intimacy, respect, or meditation. It was also used at reunions, at wedding ceremonies, and during the Pon Farr.
Spock and Uhura have a canonical love affair in the Star Trek Alternate Original Series movies . Originally envisioned as student and teacher, later scenes establish that Spock and Uhura are also romantically involved (Uhura comforts Spock with a hug; in a later scene, the two share a kiss).
Elizabeth was a binary clone created from the DNA of T’Pol, a Vulcan female, and Commander Charles Tucker III, a human male, both aboard the Starship Enterprise NX -01 served.
According to the science fantasy television series Star Trek, Mr. Spock had green blood because the oxygen-carrying agent in Vulcan blood contains copper and not iron like humans do.p>
