#once again posts getting longer than intended. whoops. the tail lore got away from me.

[a-most-beloved-fool]

Vulcan tails! I love giving Vulcans tails. But, because I am a writer more than an artist, I am cursed to think of The Implications™. So, have some headcanons. (i think there was a different one of these not too long ago, too, but i figure more can't possibly hurt!)

Prehensile - it is fully maneuverable and can be used to grasp small-ish objects. It's pretty thin, though, so it can't hold much more than 20 pounds. (even that seems like a stretch to me, with how long and thin they're usually drawn, but Vulcans are stronger than humans, so let's indulge.)

Telepathically sensitive! Not as sensitive as fingers or qui'lari, maybe, but still pretty sensitive. Compatible minds could meld using only tail contact, even if they're not the most telepathically proficient. Most of that sensitivity is concentrated near the tip, but in instances where the tail must be partially amputated for some reason, the telepathic centers have been known to redevelop farther up, on the new tip.

Tails are kept wrapped around the body (like a belt, typically, but there may be different styles of wearing them) the majority of the time. This is partially inspired by fanart, and partially because wrapping the tail around something is a Very Good Way to keep it still through emotions.* (I've seen it suggested that Vulcans would simply amputate tails as infants, but I Do Not agree with that, simply because I think that cutting perfectly functional body parts off of people without their consent is Horrifically Immoral, and also? inherently illogical? Like what do you mean you're chopping off their limb??? what if they want it later? it can't just grow back! wtf??? Cardassians might cut off tails, Vulcans Would Not. You could argue that the tails are usually kept tucked away beneath clothes, though, if you want an excuse for "no visible tail". You could also maybe argue that those who completed kolinahr would get their tails removed as a symbol of the removal of emotions, but tbh i don't like that much, either.)

I think I saw a different headcanon list somewhere on here which suggested that very young Vulcans might hang onto the tails of their parents, and I do like that concept. It's very cute. So, yes, tails are often used when caring for small children. They probably offer some kind of emotional support to Vulcans young enough to not have developed their controls yet. A telepathic pacifier or comfort blanket, if you will.

The V'Tosh Ka'tur (Vulcans without logic, like Sybok) advocate for tails to be freed. Sometimes Vulcan punks will experiment with their tails loosed as a form of rebellion. There's a whole underground movement about it.

There's an ongoing debate about whether tail use should be allowed during certain sports and gymnastics. It does help with balance, for example, but critics suggest that it's unfair to allow tail use when some Vulcan athletes will still refuse to use their tails for spiritual/Surakian reasons. They say it offers an unfair advantage to those who use tails, at the cost of more conservative Vulcans. Others say that it's illogical to ban the use of a natural body part that they almost universally possess.

(speaking of "universally possess" - I'm toying with the idea that the tail kind of begins as an umbilical cord? so before the child is born, it connects the infant to its mother, and after it's born, the cord develops bones and cartilage and transforms into another limb. idk how much sense that makes, but i like the concept.)

Because Vulcans keep their tails so contained, sometimes aliens don't realize that they have them. They assume that they're just an unusual belt that Vulcans are particularly fond of. More than one has been utterly shocked to see this supposed article of clothing twitch on its own! (sometimes, particularly young or rebellious Vulcans will deliberately play this prank on people.)

The VSA bans all tail use for tasks in their laboratories (both chemical and engineering) after a number of unfortunate accidents involving dropped specimens and tails caught in machinery. Space-OSHA is very strict about tail PPE. Tails must stay beneath the lab coat at all times!

Pre-Surakian theater often had blocking instructions for tails written into the script. The first time a modern troupe put on one of these productions, the controversy became the talk of the planet for weeks.

Similarly, pre-Surakian paintings and sculpture had a strong emphasis on tails. However, the tails were particularly prone to breaking off of the sculptures (they are very thin, after all), and large amounts of academic discussion have gone into attempting to restore the tails accurately. Unfortunately, it can be difficult to tell what position the tails would have been held in. There are only a handful of sculptures which have remained completely intact, and their tail positions are not consistent enough to provide a template, so many statue recreations are forced to guess. Some academics also suggest that there was a movement nearly 1000 years previously to deliberately remove tails from statues and destroy them!

At least one (non-percussive) musical instrument exists which requires use of a tail to play it properly.

Underground Vulcan clubs often feature risque tail dancing. This is less controversial than the plays, simply because it's not officially sanctioned and is considered to be a "display of skill and sensuality" rather than an expression of emotions.

*this has been haunting me with another silly spirk fic idea I don't yet have time to write, which is below:

Spock's tail, which is usually kept wrapped around his waist (save for when it's in use holding things), gets badly injured during a landing party. Some of the bones are broken, and because the bones are small and finicky, a good chunk of the healing needs to be done via a good old fashioned cast.

Meaning: Spock can no longer keep it wrapped around his waist.

And, having a free-hanging tail for the first time since he was three-ish, Spock learns that he is Very Bad at keeping tabs on it. Whenever he's focused on any sort of project, his tail has a mind of its own, and, naturally, it reacts most strongly to Kirk. Sometimes it wags when Kirk smiles at him, and nearly every time Kirk is close enough to him, it drifts over to touch him. They do reports together one night, and Spock's tail finds its way to Kirk's lap, and Spock, too focused on his work, doesn't notice that it's there for over an hour. Kirk does notice, and deliberately doesn't draw Spock's attention to it.

Kirk (pining) is trying his very best to not read too much into things (and is failing. oh boy does he want it to Mean Something). Spock (also pining) is just about at his wit's end trying to figure out how to control his wayward tail (because he doesn't want people to realize that it Means Something). Everyone else just finds the whole situation very cute (because they all knew from the start that the emotions were there).
