Twi'lek

Twi'leks are one of the humanoid races in the Star Wars universe. Part of the Wikipedia description follows:

Twi'leks are humanoids easily distinguished by the twin tentaclar appendages that protrude from the back of their heads. These prehensile appendages, known as "head-tails", "lekku" or "tchun-tchin," are advanced organs used for communication and cognitive functions. Like humans, Twi'leks vary greatly in appearance and have a wide variety of skin colors including shades of white, blue, green and red. Twi'leks stand between 1.6 and 2.1 meters tall.
