Piure

Pyura chilensis, called piure in Spanish and piür or piwü in Mapudungun, is a tunicate of the family Pyuridae. It was described in 1782 by Juan Ignacio Molina. The earliest mention of the P. chilensis was in 1782 by Juan Ignacio Molina in his book Saggio Sulla Storia Naturale del Chili. Molina, a Chilean abbot who was shunned from Chile along with the rest of the Jesuit missionaries, wrote this book to describe the life lived by the Chileans in the Chiloe Archipelago. He briefly describes the natives' fondness of fishing and mentions the piure as another form of sustenance for the people.
