10 Things You Didn’t Know About How Animals See the World

5. Deep-Sea Vision – Seeing in the Abyss

The deep sea is one of the most challenging environments for vision, yet many creatures have adapted to see in its perpetual darkness. Bioluminescent organisms, such as certain species of fish and jellyfish, produce their own light, which they use for communication, camouflage, and predation. Other deep-sea animals have developed large, highly sensitive eyes to detect the faintest glimmers of light. These adaptations reveal the extraordinary lengths to which evolution has gone to equip animals with the tools they need to survive in one of the most inhospitable environments on Earth.
