Visceral arches are an essential part of the aquatic vertebrate's anatomy. They help in creating the feeding mechanism and respiratory system. These arches are known by several names, such as branchial arches, gill arches, or pharyngeal arches. These arches are cartilage structures that form the foundation of gill filaments and support blood vessels and nerves. The main function of these arches is to provide a channel for water to reach the gills, where gas exchange occurs. In addition to these names, visceral arches are also called head arches, jaw arches, or mandibular arches. They are an integral part of the fish's anatomy, and their adaptation to different environments has helped them evolve over time.
