Aphotic Zone

Real World Example

Imagine walking into a windowless basement and struggling to find the light switch in complete darkness. This situation is similar to the aphotic zone of the ocean, where sunlight never penetrates, leaving it perpetually dark. Just as you rely on touch and memory to navigate the basement without light, organisms in the aphotic zone have adapted to thrive without sunlight, utilizing other senses and bioluminescence to survive in an environment where light is absent.
