First record of Pontoporia blainvillei (Gervais & d’Orbigny, 1844) (Mammalia, Cetacea, Pontoporiidae) on the coast of Arraial do Cabo, Rio de Janeiro state, southeastern Brazil

Abstract

We report the first record of Pontoporia blainvillei (Gervais & d’Orbigny, 1844), Franciscana or La Plata River Dolphin, along the coast of Arraial do Cabo, southeastern Brazil. On 8 October 2017, a newborn was stranded in the surf zone of Prainha Beach and was returned to the sea. Although an occasional record, fills a distribution gap of the species’ occurrence on the coast of Rio de Janeiro state and, consequently, helps clarify the distribution pattern of P. blainvillei along the coast of the Brazil.
