The Sleestak are an extra-dimensional reptilian bipedal humanoid species indigenous to the Land Of The Lost. They have a thin but wide-set mouths and large, round black eyes which are averse to light. Covered mostly in green scales with yellow thoraxes, they have claws on their feet and on their hands which can function as pincers. The Sleestak also have a single horn protruding backward from the top of their heads. They make a pronounced hissing sound produced by their breathing with some possible congestion condition. This is probably due to their wide set mouth and flat nostrils. They can, however, temporarily suppress their tell-tale hissing, to set up an ambush, for instance. Sleestak are taller than the average human, approximately 7 feet in height. While slow-moving, they are physically stronger than humans. They have been able to physically restrain any of the Marshalls without much effort. Their pincers can close with sufficient force to easily cut through the wooden shaft of a torch. The Sleestak have a current population of about 7,000 according to the Library of Skulls, but there were only three Sleestak costumes available for the show's production
