Ans.
Mammalian diving reflex or diving reflex is defined as a set of physiological actions in response to immersion is an example of homeostatic reflex. Homeostatic reflex is a typical, autonomous response to a particular stimulus.
The diving reflexes are shown by aquatic mammals that have evolved to conserve oxygen at the time of submersion. It helps in optimizing respiration by distributing stored oxygen preferentially to heart and brain, and thus, enables submersion for a longer time.
Thus, the correct answer is 'homeostatic reflex.'
