The invasive Asiatic freshwater bivalve Corbicula fluminea is regarded as a pest in several countries including Brazil. Two water birds native to South America, the limpkin Aramus guarauna and the common gallinule Gallinula galeata, are herein recorded preying on C. fluminea in a pond of an urban park in South-eastern Brazil. The exotic clam is becoming increasingly common in the diet of both these water birds. This trend is likely due to its increasing population and the consequent rarity of the habitual prey (apple snails and native clams) for the mollusc-specialised limpkin, besides being an accessible animal protein source for the omnivorous gallinule.

Ontogenesis of the outer demibranch of ctenidium was observed in the different groups of freshwater bivalvos: najades (Unionidae), fingernail and pill clams (Sphaeriidae), and Dreissena, with some data on Corbicula (Corbiculidae) and Hypanis (Cardiidae) also presented. Established are the sequence of stages as well as growth patterns. Three different strategies of the outer demibranch growth and development specific for unionids, sphaeriids, and Dreissena, are described. Probable phylogenetic transition between these strategies is discussed. Some trends of the evolution of gill ontogenesis within the family Sphaeriidae are traced up. It was shown that the stage at which the outer demibranch appears is an important morphogenetic factor determining size and position of the organ in fingernail and pill clams, and, presumably, in bivalve molluscs in general.
