How does a fish survive in the midnight zone?

In the midnight zone, which is the deep ocean below 1,000 meters where sunlight doesn’t penetrate, fish have adapted to extreme conditions such as high pressure and low temperatures. Many species possess bioluminescent organs to attract prey or communicate. They often have large mouths and flexible bodies to consume scarce food resources, while some have specialized adaptations like enhanced sensory organs to navigate and find food in total darkness. These adaptations enable them to thrive despite the challenging environment.
