- Head
Front part of the fish containing the brain, sensory organs, mouth, and gills, responsible for feeding, sensing, and guiding movement.
- Mouth
Opening at the front of the head used for taking in food and water.

Bony structure supporting the mouth, allowing opening and closing for feeding.
- Teeth
Small hard structures in the mouth used to grasp, crush, or tear food.
- Tongue
Muscular organ in the mouth that helps move food and assists in swallowing.
- Nostril
Paired openings on the head used for detecting smells in water.
- Eye
Organ for vision, allowing the fish to see its environment and detect movement or predators.
- Gill
Respiratory organ that extracts oxygen from water and releases carbon dioxide.
- Gill cover
Protective bony flap (operculum) that shields the gills and assists in water flow.
- Operculum
Hard bony plate covering the gill chamber, aiding in respiration and protection.
- Gill arch
Curved bony structure supporting gill filaments and maintaining gill shape.
- Gill filament
Thin, feathery structures on gills where gas exchange occurs with water.
- Body
Main part of the fish containing organs, muscles, and skeleton, giving shape and enabling movement.
- Trunk
Central part of the body between head and tail that houses vital organs.
- Tail
Posterior end of the fish used for propulsion and steering.
- Caudal fin
Fin at the tail end that provides thrust and aids in swimming.
- Dorsal fin
Fin on the back that helps with balance and stability during swimming.
- Pectoral fin
Paired fins near the head used for steering, lifting, and maneuvering.
