Gill Morphology in the Red Swamp Freshwater Crayfish Procambarus clarkii (Crustacea: Decapoda: Cambarids) (Girard 1852) from the River Nile and its Branches in Egypt

The aim of the present study was focused on and describes the gross morphological and scanning electron microscopical features of the gill of the red swamp freshwater crayfish. Our results noted that: all gills have the same general structure and appearance. The gill consists of axis with numerous f...
