A Tenka is the singular form of a unique biological appendage possessed by Luxans in the mythology of the Farscape television series. Luxans possess eight tenkas, or tentacles, which extend downward from the base of their skull. They also possess a shorter, flatter chin tenka which on males is considered an erogenous zone. Members of the Ilanic race, genetic cousins to Luxans, possess similar tentacles, though there's are significantly more prominent. It is a common practice in Luxan culture to have one's tenkas tatooed. This may be reflective of a Luxan's standing amongst the warrior caste.
