Male frogs can be distinguished from female frogs due to the presence of :
A. Bulging eyes
B. Vocal sacs
C. Webbed digits in feet
D. Copulatory pad on first digit of fore limbs
E. Olive green-coloured skin with dark irregular spots
Choose the correct answer from the options given below :
- A B and C only
- B C and E only
- C A and B only
- D B and D only
Answer & Solution
Correct Answer
(D) B and D only
Step-by-step Solution
Detailed explanation
(D) B and D only
Male frogs can be distinguished from female frogs by the presence of sound-producing vocal sacs and a copulatory pad on the first digit of the forelimbs. These structures are absent in female frogs.
Bulging eyes, webbed digits in feet, and olive green-coloured skin with dark irregular spots are morphological features common to both male and female frogs.
Therefore, only statements B and D represent the distinguishing features of male frogs.
