Quizplus · Accepted Answer

The abyssal zone is the deepest part of the ocean with extreme conditions such as low temperature, high pressure, and permanent darkness. Some fish and crustaceans have developed adaptations to survive in this zone, including bioluminescence or eyes that are sensitive to the faint light that can penetrate this depth. Some species of anglerfish, for example, have a glowing lure on their head to attract prey, while others have developed large eyes to detect the faint light of bioluminescent creatures. Therefore, the abyssal zone may have some fish and crustaceans that are blind or have their own light sources.
