Adaptations to deep-sea environments

Deep-sea adaptations are specialized features that help organisms survive in extreme conditions like high pressure, low temperatures, and complete darkness. Many deep-sea creatures have soft, flexible bodies to withstand pressure, and some produce their own light—bioluminescence—to attract prey or communicate. Others have large mouths and expandable stomachs to maximize food intake when meals are scarce. Enhanced sensory organs help detect movement and chemical signals in the dark. Overall, these adaptations enable deep-sea dwellers to thrive in an environment with limited resources, extreme conditions, and perpetual darkness.
