The euphotic zone is the layer closer to the surface that receives enough light for photosynthesis to occur. Beneath lies the disphotic zone, which is illuminated but so poorly that rates of respiration exceed those of photosynthesis.

What is an example of euphotic zone?

Animals: Examples of euphotic zone animals include most ocean fish (including sharks and rays), man-o'-war, jellyfish, sea turtles, seals, coral, and zooplankton. ... Countershading is when an animal is light on its underside and dark on its upper parts.

What zone is the euphotic zone in?

The top zone is the euphotic or sunlit zone. This is the ocean zone that sunlight penetrates. Because this zone gets sunlight, photosynthesis can occur and plants can grow here. The sunlit zone goes down to about 660 feet.
