Resumo Corythomantis greeningi, a casque-headed tree frog, was studied in the field and in captivity. This species belongs to a monotypic genus, and together with other species of anurans, possesses a differentiated head which is flat, very rough and presenting cranial co-ossification with the skin. These are characteristics that are usually associated with phragmotic behaviour which is supposed to have a role in water saving and protection against predators. Observations were focused on the characteristics of the species which make it adapted to life in the Brazilian semi-arid (caatinga). Data about the body and external anatomy of the head, integument morphology, life, reproduction, interest for sheltering and defense against desiccation is presented. Finally, it is proposed that adaptation of this species to the dry environment is probably the result of the synergism of a number of different strategies against water loss, including phragmosis.
