The Red Sea Sharks
Oliveira "de" Figueira is the form used by Hergé in the later appearances of this character. He is named Oliveira "da" Figueira (lit. "Olive-tree of the Fig-tree") in his initial appearances. For "The Red Sea Sharks" Hergé changed his name to Oliveira de Figueira. (Both spellings are correct in Portuguese: "de" means "of", while "da" means "of the".)
