Fish anatomy
Fish Anatomy
Fish anatomy is the study of the form or morphology of fishes. It can be contrasted with fish physiology, which is the study of how the component parts of fish function together in the living fish.
Pronunciation
Fish Anatomy: /fɪʃ/ /əˈnatəmi/
Etymology
The term "Fish" comes from the Old English "fisc" which is related to the Old High German "fisc" meaning fish. The term "Anatomy" comes from the Greek "anatome" which means dissection.

Overview
Fish are complex organisms that have evolved over millions of years to inhabit a vast range of aquatic environments. The anatomy of fish is often shaped by the physical characteristics of water, the medium in which fish live.
Fish anatomy includes various parts such as the gills, fins, scales, swim bladder, and lateral line. Each of these parts plays a crucial role in the survival and adaptation of fish in their respective environments.
- Gills: The gills are the respiratory organs of fish, extracting dissolved oxygen from water and excreting carbon dioxide.
- Fins: Fins are used for steering, balance, and propulsion. Different types of fins include the dorsal, pectoral, pelvic, anal, and caudal fins.
- Scales: Scales provide external protection to the fish's body. They can vary in size, shape, and arrangement, depending on the species of fish.
- Swim Bladder: The swim bladder is an internal gas-filled organ that helps a fish control its buoyancy and stay at the current water depth without having to waste energy in swimming.
- Lateral Line: The lateral line is a sensory organ that detects movement and vibration in the surrounding water, helping fish to navigate, hunt, and avoid predators.
