Neste artigo, apresentamos o primeiro registro de uma fêmea de Metachirus myosuros carregando dois filhotes nas costas, em conjunto com dados sobre a reprodução da espécie, obtidos durante dois estudos de monitoramento de fauna no estado do Rio de Janeiro, Brasil. O baixo número de filhotes (n = 2) carregados pela fêmea quando comparado ao tamanho médio da ninhada (n = 8.33), sugere uma alta taxa de mortalidade para a espécie nos primeiros meses de vida. Este registro se soma a outros estudos que indicam que a sobrevivência precoce é uma fase crítica no ciclo de vida dos marsupiais.
