Marriage was unknown among the Ishi Tib, and no Ishi Tib knew who his or her parents or children were. Ishi Tib reproduction was governed by the needs of the school, with fertilized eggs laid in hatcheries near the reefs, and children raised communally. The most important laws of the Ishi Tib were concerned with ecological preservation. Schools were governed by representatives who were elected to one-year terms.
Their society was centered on small communities (called 'schools') of up to 10,000 Ishi Tib. As they evolved intelligence, their cities were built on these same coral reefs, with underwater farms which grew fish, seaweed, and crustaceans for food. Ishi Tib evolved from fish who escaped predators by jumping out of the oceans and on to the above-water portions of Tibrin's coral reefs. Their green skins retained humidity, but an Ishi Tib 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. Their lungs doubled as internal gills, and they had an acute sense of smell on land or in the water. Their heads were often described as star-shaped, with their eyestalks, beaks, and cheek pouches forming a five-pointed star. The Ishi Tib were amphibious beings with large eyes on stalks and beak-like mouths.
Ishi Tib were a sentient species from the planet of Tibrin.
