RESUMO
The ilha de São Sebastião is located in one of the most representative remnants of the Atlantic forest, and although its great importance, the knowledge of herpetofaunal assemblages remain poorly known, mainly in ecology. Thus, considering the data or quantitative studies absence, this work goal the herpetofaunal ecology, focusing: composition, richness, dominance, relative abundance, habitat use and macrobabitat use. Fieldwork included pitfall traps with drift fences, funnel traps, time constrained search, sampling by car and incidental encounters. The fieldwork data was complemented by herpetological collections and literature records. We recorded 34 species of anuran amphibians, one gymnophiona, one amphisbenid, ten lizards, 26 species of snakes and one turtle. There were many differences on macrohabitat use, and the main were litter, shrub and ground. The most of species is specialist in the macrohabitat use. In the habitat use, the species distribution shows that the assemblage structure is complex, with superior diversity in the intermediate altitude.
