Question

The mammal who has no scrotum and the testis lie in abdominal cavity is

• A. Bat
• B. Dog
• C. Elephant
• D. None of the above

Answer 1

The correct option is C Elephant

Testis descends down in the scrotal sacs to maintain a specific temperature required for the spermatogenesis. Elephant's testes do not descend into a scrotum during embryonic development and remain intra-abdominal after birth. This feature is characteristic to aquatic mammals, whose testes need to be protected from the cold.

So, the correct answer is option C.
