Occulans are a biped species who developed an interstellar space faring civilisation. They have two limbs with feet that looks like hands which they use for both prehension and locomotion. Their head is Y-shaped with a mouth at the Y's junction, a one-nostril nose on each arm of the Y and an eye at each summit.
Occulans are possibly in contact with at least 106 species as Baabians know of that many species who have sent emissaries to Earth who have never returned. Among them, the Greys, the Merdoc and the Thurman. An Occulan called Larry Longeyes was kept captive on Earth for a while.
