Fish Anatomy Overview

Gills (Operculum): Respiratory structures for gas exchange in water; operculum is the protective covering.
Liver: Large organ responsible for metabolism, detoxification, and storage of nutrients; plays a role in digestion by producing bile.
Pelvic Fins: Paired fins located on the ventral side; aid in balance and maneuvering, contributing to stability in the water.
Stomach: Organ for storing and breaking down food; employs enzymes and acid for digestion.
Anal Fin: Located on the underside of the fish; helps with stability and steering as the fish swims.
Caudal Fin: Tail fin that provides propulsion; important for movement, speed, and direction change.
Lateral Line: Sensory organ that detects water movements and vibrations, crucial for navigation and locating prey.
Dorsal Fin: Positioned on the back; assists with stability during swimming, preventing rolling.
Swim Bladder: Gas-filled organ that helps fish maintain buoyancy and control their depth in the water.
