The Malkoth are a sentient species. The Malkoth were amphibious beings with large eyes on stalks and beak-like mouths. Their heads were often described as star-shaped, with their eyestalks, beaks, and cheek pouches forming a five-pointed star. Their lungs doubled as internal gills, and they had an acute sense of smell on land or in the water. Their green skins retained humidity, but an Malkoth had to bathe in salt water every thirty hours or so, or their skin would crack open, resulting in internal and external bleeding and death.
