CALUSA

extinct North American Indian tribe that inhabited the southwest coast of Florida from Tampa Bay to Cape Sable and Cape Florida, together with all the outlying keys. According to some authorities their territory also extended inland as far as Lake Okeechobee. Their linguistic affiliation is not certain. Their estimated population in 1650 was 3,000 living in 50 villages. The Calusa relied more on the sea than on agriculture for their livelihood. They made tools and weapons of seashells and fish bones. Their dwellings were of wood, built on piles, and their sacred buildings were erected on flat-topped mounds. They were fierce fighters and accomplished seamen, paddling their dugout canoes around the Florida coast. In their early period there is evidence of sacrifice of captives and of cannibalism. The Calusa also journeyed to Cuba and other Caribbean islands, trading in fish, skins, and amber. During the 16th century they defended their shores from a succession of Spanish explorers. One theory of their disappearance is that they emigrated to Cuba during the 18th century as a result of recurring invasions by the Creek and English. The Seminole, who moved into Florida early in the 19th century, maintained that the remnants of the Calusa went west with those Seminoles who were removed to Oklahoma.
