Amphipoda, a taxonomically diverse group within Crustacea, exhibit a wide range of adaptations to different habitats. These adaptations include thriving in marine, freshwater, terrestrial, and even parasitic lifestyles. Despite the ecological and evolutionary significance of these adaptations, the molecular mechanisms behind them remain poorly understood. Comparative transcriptomics offers a powerful approach to unravel the genetic basis of these habitat adaptations and identify key genes and pathways involved. In this study, we employed comparative transcriptomics to analyze the gene expression profiles of amphipods from diverse habitats. Using Illumina NextSeq, we generated transcriptomic data from the skeleton shrimp Caprella dilatata (Caprellidae) and the whale louse Cyamus boopis (Cyamidae). Coupling available data from open repositories, we compared the transcriptomic profiles of amphipods from different habitats, we anticipate discovering genes and pathways associated with specific adaptive traits, such as genes related to osmoregulation, salinity tolerance, desiccation resistance, or other habitat-specific adaptations. These findings will contribute to our understanding of the genetic basis of habitat adaptations in amphipods. Additionally, this comparative transcriptomic analysis will help elucidate the evolutionary relationships among amphipod species with different habitat preferences. By analyzing gene expression profiles and identifying habitat-specific genes and pathways, we will gain valuable insights into the genetic basis of these adaptations. This research will contribute to our understanding of the ecological and evolutionary processes shaping the diversity of amphipods within the order Eumalacostraca.
