EtymologyThe specific epithet “potyguara” is a Tupi indigenous name, here employed as a noun in apposition (poty = shrimp; `war = eaters) (Gregório 1980). This name refers to the denomination of a native people that occupied historically the northeastern coast of Brazil, for which the shrimp fishing is one of the most traditional economic activities.
