Fish Physiology
Fish physiology refers to the biological functions and processes that enable fish to survive and thrive in aquatic environments. Key aspects include their gills, which extract oxygen from water; a specialized circulatory system that efficiently transports oxygen and nutrients; and a buoyant swim bladder that helps them maintain depth. Fish also possess a lateral line system to detect water vibrations and navigate their surroundings. Their scales, made of thin bony plates, protect their bodies and reduce drag. Together, these features allow fish to adapt to various habitats and fulfill roles in aquatic ecosystems.
