Vedclass · Answer

(D) In many seasonal breeders,such as certain mammals like bats and rodents,the testes are not permanently located in the scrotum. During the non-breeding season,the testes retract into the abdominal cavity to protect them from external environmental conditions. As the breeding season approaches,the testes descend into the scrotum to facilitate spermatogenesis at a temperature lower than the core body temperature. Among the given options,bats $(Chiroptera)$ exhibit this seasonal migration of the testes.

In which of the following organisms do the testes descend into the scrotum during the breeding season but move back into the abdominal cavity during the non-breeding season?
