Description
Summary:ABSTRACTRecords of southern elephant seals (Mirounga leonina) as vagrants along the SE Brazilian coast date back the late 50’s and have been relatively common over the last decades. These large marine mammals usually call much attention when they arrive on tropical beaches worldwide and are generally treated as ‘occasional visitors’ and ‘vagrants’. This note reports on sightings of a youngelephant seal along SE Brazil in the summer and autumn of 2020. We also reviewed records in both the literature and open sources, totaling eight records of infant southern elephant seals known since the late 70’s along the Brazilian coast. It was noted that the arrival of an infant in February of 2020is coincident with a previous cyclonic activity off the SE and NE Brazilian coast. The connection of such unlikely records of pinnipeds on tropical beaches and extreme weather events associated to ocean currents should be better evaluated in the context of climatic change RESUMOÉ reportada uma ocorrência recente de um infante de elefante-marinho (Mirounga leonina) na costa do estado do Rio de Janeiro com um intervalo aproximado de um mês entre as avistagens do mesmo indivíduo. A comparação das fotografias obtidas em ambos os registros permitiu a comparação e confirmação. Em adição, se discute a presença de infantes na costa brasileira, que totalizam oito casos, mas que não apontam uma sazonalidade marcada, mas uma tendência aos registros serem reportados em junho, seguido por outubro e novembro. Como o presente registro se deu em janeiro, pico do verão, fatores climáticos de larga escala podem estar atuando para deslocar alguns indivíduos muito ao longe das suas colônias.Palavras-chave: Mirounga leonina; Movimentos; Vagante; Atlântico Sul.
