Recent advances in genetic manipulation and genome sequencing have paved the way for a new generation of research organisms. The amphipod crustacean Parhyale hawaiensis is one such system. Parhyale are easy to rear and offer large broods of embryos amenable to injection, dissection, and live imaging. Foundational work has described Parhyale embryonic development, while advancements in genetic manipulation using CRISPR-Cas9 and other techniques, combined with genome and transcriptome sequencing, have enabled its use in studies of arthropod development, evolution, and regeneration. This study introduces Parhyale development and life history, a catalog of techniques and resources for Parhyale research, and two case studies illustrating its power as a comparative research system. This article is categorized under: Comparative Development and Evolution > Evolutionary Novelties Adult Stem Cells, Tissue Renewal, and Regeneration > Regeneration Comparative Development and Evolution > Model Systems Comparative Development and Evolution > Body Plan Evolution.
Keywords: arthropod; crustacean; development; evodevo; evolution.
