Question
Mention the role of different types of fins in the locomotion of fish.
Answer
Different types of fins in fishes play various roles in their locomotion. Here are some of the major roles of different fins:
- Caudal fin (tail fin): The main role of the caudal fin is to provide propulsion to the fish. It is the primary source of forward movement in most fishes.
- Dorsal fin: The dorsal fin helps the fish to maintain its balance and stability while swimming. It also helps in changing direction and in sudden bursts of speed.
- Anal fin: The anal fin also helps in stability and balance while swimming. It also assists in braking and in making tight turns.
- Pectoral fin: The pectoral fin is responsible for steering and turning in fish. It also helps in maintaining balance and in braking.
- Pelvic fin: The pelvic fin also helps in steering and turning, as well as in braking and in maintaining balance.
