Abstract: Feeding behavior of immature green turtles, Chelonia mydas, has been observed on rocky shores along the northern part of State of São Paulo, southeastern Brazil. This turtle forages on underwater ledges, at depths of 1 to 3 m and grazes on benthic algae. The turtle seems to visually scan the algae during feeding and moves slowly, walking from one patch of vegetation to another. Gut contents of four individuals (331-452 mmCCL) consisted mainly of red and brown algae. Comparisons between gut contents and algae growing at the grazing sites, together with scanning behavior suggest selective feeding. Syntopic large herbivorous fishes of the genera Kyphosus, Sparisma, and Acanthurus showed little feeding overlap with the green turtle.
