Also known as: lekku
Lekku (singular lek), also referred to as head-tails or brain-tails, are long, fleshy appendages that protrude from the head of all Twi'Leks, Togrutas, and male Ozrelansos. The Togruta sport three of them, while the other species have two (occasionally four, in the case of Twi'leks).
