Amphidromous shrimps (Decapoda: Caridea): current knowledge and future research.

The article focuses on amphidromous caridean shrimps, which migrate between freshwater and marine environments and play key ecological and commercial roles in tropical ecosystems. It provides a comprehensive inventory of amphidromous shrimp species, primarily from the families Atyidae and Palaemonidae (genus Macrobrachium), detailing their global distribution, ecological functions, and the threats they face, including habitat degradation, introduced species, overfishing, and climate change. The review highlights a significant research bias toward commercially important Macrobrachium species, especially Macrobrachium rosenbergii, while many diverse Atyidae species remain understudied. The authors advocate for expanded experimental biology research on lesser-known species to better understand their physiology, ecology, and responses to environmental stressors, which is essential for effective conservation and sustainable management.
