What should divers consider regarding marine life during a night dive?

• A. More marine life is active during the day
• B. Many species exhibit different behaviors at night
• C. All marine life is inactive in total darkness
• D. Only large fish are active at night

Answer: (B)

During a night dive, divers should be aware that many marine species exhibit different behaviors under the cover of darkness. This phenomenon is known as nocturnal behavior, which includes changes in feeding patterns, mating rituals, and patterns of movement. Certain species take advantage of the night for hunting, while others may seek shelter or exhibit camouflage in response to reduced visibility and the presence of predators. Understanding these behaviors enhances the diving experience and increases the chances of observing unique and fascinating marine life that may not be active during the day. This aspect of night diving can lead to extraordinary encounters and a deeper appreciation for the underwater ecosystem. The other options reflect misunderstandings about marine life behavior. The idea that all marine life is inactive in total darkness is inaccurate, as many organisms thrive in the absence of sunlight. Similarly, asserting that only large fish are active at night ignores the diversity of smaller species that also engage in significant activity after dark. Lastly, suggesting that more marine life is active during the day overlooks those creatures that are specifically adapted to nocturnal lifestyles.
