Fish is an aquatic animal. There are various adaptations in fish that help them to survive in water.
Adaptation:
Adaptation is the presence of specific features or habits that help a plant or animal to live in its surrounding.
Reason for adaptation of fish in aquatic habitat:
1. Body shape: Fishes have streamlined body shapes ie.. boat-shaped structures. This shape is to get the least resistance during swimming.
2. Gills: Fishes have gills to exchange gasses.
3. Caudal fin:
Shapes come under the median fin which makes their body move forward and it functions as a rudder and helps them to change direction.
4. Scales: The entire body of fish is covered with scales to protect them from decay in water.
