"The name Uirapuru carried over to Jiu Jitsu and MMA from Marcelo's Capoeira days. When Marcelo Azevedo trained capoeira at the age of 10, his instructor used to have a book with him named "1001 Animals from All Over the World". Anyone who started classes at this gym was told to open the book on a random page, and whichever page they landed on they would be nicknamed the animal on that page. Marcelo opened on the Uirapuru ( Musician Wren in English)."
