Surface ultrastructure of the gills of odontesthes bonariensis (Valenciennes, 1835) (Teleostei: Atheriniformes) from a temperate shallow lake
We studied the gill epithelium of juveniles of Odontesthes bonariensis using scanning electron microscopy with a particular interest in the relationship between cell morphology and the different functional aspects of gills. The specimens used were collected in Laguna de los Padres, Buenos Aires Prov...
