Which marine animal is described as living at great depths and maintaining its size despite scarce food sources?

• A. Giant Squid
• B. Blue Whale
• C. Whale Shark
• D. Anglerfish

Answer: (A)

Deep-sea gigantism explains why some animals stay large in the depths where food is scarce. The giant squid lives in very deep waters, often hundreds to over a thousand meters down, where meals are infrequent. A large body helps store energy and survive longer fasting periods, so its substantial size persists even when prey is hard to come by. That combination of extreme depth habitat and maintaining a large size in a resource-poor environment makes the giant squid the best fit for the description. The other animals don’t align as closely with both living at such depths and exhibiting that pattern of size maintenance under scarcity.
