WebbKidneys are the primary excretory organ in fishes. They have endocrine glands that control and regulate many kinds of body functions. The fish brain is divided into several anatomical and functional parts that integrate responses and activities such as taste, sight, hearing, or smell. An important sensory system is the lateral line system.
