The Kaleans are a reptilian humanoid species native to the Alpha or Beta Quadrant. Kaleanss do not have sweat glands, and their bodies' hydration system is not based on water. Instead they drink a brown liquid that they call "taratt-aash". Their saliva has healing properties, as it can quickly repair skin abrasions. Their cellular structure is not capable of handling rapid temperature changes. They had rocky relationships with the humans by 2568.
