Marine animals have evolved specialized vision adaptations for underwater conditions:
- Deep-sea fish often have large, sensitive eyes that can detect the faintest blue-green light
- Shallow-water fish typically have color vision similar to humans
- Many marine animals can see ultraviolet light, which penetrates water well
Some species, like mantis shrimp, have incredibly complex visual systems that can detect 12 color channels (compared to humans’ three) and even see polarized light. These adaptations help them identify prey, mates, and predators in their underwater environment where natural color is limited.
