Shrimp can be found in various marine environments, including the sunlit zone. Many shrimp species inhabit shallow coastal waters, where sunlight can penetrate and support the growth of marine plants and algae. These areas provide food sources and shelter for shrimp. However, it's worth noting that not all shrimp species are limited to the sunlit zone. Some deep-sea shrimp species have evolved adaptations to survive in the dark and cold conditions found in the depths of the ocean.
