A gaya is a type of animal indigenous to the planet Angira, an herbivorous mammal.
Specifics
A gaya is similar to a goat, but about 10 feet long (3 meters) and with longer hair. Angirans domesticated them, weaving their wool-like hair into blankets and other garments. Gaya are common in regions near the royal palace, including the settlement of Guh and the province of Kotah.
History
Puga often spent winter nights as a young boy huddled with gaya in a stable, their warmth providing more comfort against the chilly air than his bedroom, though the behavior frustrated his father.
In 2266, during a visit to Guh, Spock, Hikaru Sulu, Urmi and Prince Vikram were kept in a gaya stable under guard by a local militia. (TOS novel: Shadow Lord)
