The third group of fish is the class OSTEICHTHYES, or bony fish. The function of the respiratory system is to enable gas exchange between the fish and the water, a process that is necessary for the vital functions to be performed. Crustaceans are invertebrates with a hard exoskeleton ( carapace ), a segmented body that is bilaterally symmetrical, more than four pairs of jointed appendages ("legs") and an open circulatory system (the "blood" does not flow in a closed loop). The presence of a backbone has led to classes of animals with complex circulatory system, advanced nervous systems and acute sensory organs. The circulatory system performs a variety of functions including: transport of respiratory gases, nutrients, metabolic wastes, hormones and antibodies. In osteichthyes, the gills are covered by a bony protective flap called the operculum. 350 spp.) Bone strong but not brittle. Closed circuit circulatory system. These select Elasmobranchii have the ability to withstand both salt and fresh water. The respiratory system of animals is crucial for the life as it allows the exchange of gases between an organism and the environment.
