A streamlined body, scales and gills are the adaptations found in fish..

Adaptations in Fish

1. Fins:
Fins play a crucial role in a fish's movement, stability, and steering. Different types of fins, such as dorsal, pectoral, pelvic, and caudal fins, help fish navigate through water with ease.

2. Gills:
Gills are specialized respiratory organs that enable fish to extract oxygen from water. Fish gills have a large surface area with thin membranes that facilitate efficient gas exchange.

3. Swim Bladder:
The swim bladder is an internal gas-filled organ that helps fish control their buoyancy. By adjusting the amount of gas in the swim bladder, fish can move up or down in the water column.

4. Scales:
Scales provide protection to fish by forming a tough, waterproof layer on their skin. These overlapping structures reduce water resistance and prevent injuries from predators.

5. Lateral Line System:
The lateral line system consists of sensory organs that detect changes in water pressure and vibrations. This adaptation helps fish sense movement in the surrounding water and avoid potential threats.

6. Camouflage:
Many fish species have evolved camouflage patterns to blend in with their environment and avoid predators. This adaptation allows fish to hide in plain sight and increase their chances of survival.
