Question

Which fin are paired in fishes?

• A. Dorsal fin
• B. Anal fin
• C. Pelvic fin
• D. None of the above

Answer 1

Answer: (C)

Pelvic fin

In fishes, the pelvic or ventral fins are paired fins and located ventrally below and behind the pectoral fins. It helps the fish in going up or down through the water, turning sharply and stopping quickly. Apart from pelvic fins, pectoral fins are also paired in fishes. Dorsal and anal fins all are not paired. Hence, option C is the correct answer.
