Shrimp are primarily considered to be part of the nekton group. Nekton refers to aquatic animals that are capable of swimming and moving independently of water currents. While some shrimp species can reside on the ocean floor and are benthic in their behavior, especially during certain life stages or when they are hiding from predators, the majority of shrimp are known for their ability to swim freely in the water column. This swimming capability places them in the nekton category.
Additionally, it’s important to note that the classification of shrimp can vary based on their specific habitat and life stage. Many juvenile shrimp may inhabit the benthic zone while they grow, but as they mature, they tend to explore more of the water column, showcasing their nektonic characteristics. So, while shrimp can exhibit both nektonic and benthic behaviors, they are primarily recognized as nekton due to their swimming abilities.
