Resumo
This species showed feeding activily ali year long. Although zooplancton, protozooplancton and other organisms have been found in the stomaches, this species can be considered, broadly speaking, herbivorous since a great amount of seaweed was found in its diet. Fulness of the stomachs was not associated with sex difference. Full stomachs were found throughout the period. Variations according to the estimated periods were not found.

Although zooplancton, protozooplancton and other organisms have been found in the stomaches, this species can be considered, broadly speaking, herbivorous since a great amount of seaweed was found in its diet. Fulness of the stomachs was not associated with sex difference. Full stomachs were found throughout the period. Variations according to the estimated periods were not found.
