Question

In sharks, the mouth and nares are

• A. Ventral and dorsal
• B. Terminal and dorsal
• C. Both ventral
• D. Dorsal and ventral

Answer 1

The correct option is C Both ventral

• Dorsal means upper side or the backside of an animal
• Ventral means abdominal or underside of an animal

Sharks belong to class Chondrichthyes in which fishes have a ventrally placed mouth and external nares (nostrils) are present on the ventral side of the head.

Hence, both the mouth and nares are ventral.

So, the correct answer is 'Both ventral'.
