Ahsoka is of the Togruta species. Like Twi'leks, they have head appendices called Lekku, that grow longer with age. In "Star Wars: The Clone Wars" (up to 19BBY), Ahsoka's Lekku are short. In "Star Wars Rebels" (1BBY), they have grown considerably longer. Now, 10 years later, in the live action version, they are short again. Jedi Master Shaak Ti shows the normal adult length of Togruta Lekku.
