Tigriopus

Tigriopus is a genus of harpacticoid copepods, which are small crustaceans found in marine and brackish environments worldwide. These copepods are characterized by their relatively large size compared to other harpacticoids and their distinctive color, often appearing orange or red. They are benthic organisms, meaning they live on the seafloor or in sediments, and are a common component of meiofauna communities.

Species within the Tigriopus genus are known to inhabit a variety of habitats, including intertidal zones, salt marshes, and tide pools. They are often found in areas with fluctuating salinity and temperature, demonstrating a notable tolerance for harsh environmental conditions. Their diet typically consists of algae and detritus, playing a role in nutrient cycling within their ecosystems.

Tigriopus species have also garnered attention in scientific research due to their adaptability and potential as model organisms. Their relatively simple life cycle and ease of culture in laboratory settings make them useful for studying topics such as ecotoxicology, population dynamics, and the effects of environmental stress on marine invertebrates. Some research has explored their potential in aquaculture, though this is not a widespread application. The genus is distributed globally, with various species identified across different continents and oceanic regions.
