Bothrops insularis (Amaral, 1922)

A jararaca-ilhoa (nome científico: Bothrops insularis) é uma serpente sui generis, adaptada a vida arborícola ou semi arborícola, o que se reflete em diversos aspectos de sua morfologia e comportamento. Vive exclusivamente na Ilha da Queimada Grande a 35 km do litoral paulista, entre os municípios de Itanhaém e Peruíbe. Calculava-se existir cerca de três a cinco mil indivíduos na ilha, mas notícias recentes, avaliando por estimativa, declaram haver cerca de 2.000 animais apenas. Técnicos estão microchipando as serpentes para se possa chegar a uma contagem mais precisa. A jararaca-ilhoa não tem concorrentes nem predadores. Pode sobreviver cerca de seis meses sem se alimentar. Alimenta-se normalmente comendo aves e seus ovos, especialmente do atobá-pardo, muito comum na ilha.
