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...
