Lekku

Lekku (singular lek), also referred to as head-tails or brain-tails, were long, fleshy appendages that protruded from the head of all Twi'leks, Togruta, Walunas and male Ozrelanso. The Togruta sported three of them, while the other species had two (occasionally four, in the case of Twi'leks).
==In Twi'leks==
In Twi'leks, lekku were shapely prehensile tentacles that grew from the crown of their skulls.Star Wars: Absolutely Everything You Need to Know While Twi'leks normally had two lekku, certain individuals like Orn Free Taa had four of them. Super-sensitive lekku could be used for grabbing and holding objects. Those organs were very sensitive to touch, and a damaged lek could cause severe harm to a Twi'lek; Squoxx died within an hour after one of his lekku was bitten off. Lekku loss did not always kill Twi'leks, however: the Jedi Master Loden Greatstorm lived for some time after his lekku were cut off while he was in the captivity of the Nihil. If not for his later death in battle, Greatstorm would have been fitted with prosthetic replacements.The High Republic: The Rising Storm
In addition to their spoken language, RylLords of the Sith, the Twi'leks could also communicate through subtle lekku gestures. For example, the right lek tip raised meant "hello," the left lek tip dipped meant "goodbye," both lekku tips crossed over twice meant "love you," and both lekku tips jabbed into the speaker's back meant "may spice salt your wounds!" Despite the high sensitivity of those organs, Tw'lek Jedi Matthea Cathley had a habit of smoothing over her Lekku with her hands if her mind was racing through thoughts. Her friend Tey Sirrek also claimed her lekku twitched whenever she lied, which she disputed. She also demonstrated the ability to shake her lekku.The High Republic: Path of Vengeance some Twi'leks like Cham Syndulla tattooed their lekku. Some wore them simply hanging down their back or falling over the chestObi-Wan and Anakin 2, while others like Bib Fortuna bent them around the neck or shoulders for aesthetic purposes.
==In Togruta==
The name "lekku" was also used to describe the striped head-tails of the Togruta. That species, however, had three such appendages: two lekku to the front, falling over the chest, and one thicker lek that was centered at the rear base of their skull.Star Wars Rebels: Visual Guide: Epic Battles As seen on Governor Gupat Roshti, male Togruta's lekku were shorter than those of females. The loss of a lek, as seen on the bartender Selda, was not a crippling injury, but the appendages did not grow back afterwards. A Togruta's montrals were connected to their lekku. The color of a Togruta's lekku was determined by their DNA.
Lekku grew as their wearer matured.Star Wars: Aliens of the Galaxy As an infant, lekku were only found around the Togruta's head. In adolescence, the lekku extended only slightly past the collarbones, but could reach below the waist by adulthood.Star Wars: Aliens of the Galaxy The elder Togruta Gantika had lekku that only extended to her stomach.
==In Ozrelanso==
In male Ozrelanso, lekku were tentacles that grew on the sides of their skullsStar Wars: The Rise of Skywalker: The Visual Dictionary.
==Behind the scenes==
Lekku first appeared in the film Star Wars: Episode VI Return of the Jedi, along with the Twi'lek species. In The High Republic: Into the Dark, Togruta Jedi Master Jora Malli's lekku are misidentified as her montrals when the appendages are described as streaming behind her when the airspeeder she is riding goes into a dive.The High Republic: Into the Dark Ahsoka Tano's lekku lost length between her animated by 4 BBY,Star Wars: Timelines and live action depictions. For Ahsoka, her lekku were slightly extended.
