In Taíno spiritual beliefs, hupias (ghost spirits of those who had died) were contrasted with goeiza, spirits of the living. While a living "goieza" had definite form, after passing away the spirit was released as a "hupia" and went to live in a remote earthly paradise called Coaybay. Hupias were believed to be able to assume many forms, sometimes appearing as faceless people or taking the form of a deceased loved one. Hupias in human form could always be distinguished by their lack of a navel. Hupias were also associated with bats and said to hide or sleep during the day and come out at night to eat guava fruit.
