Genome-wide identification of 216 G protein-coupled receptor (GPCR) genes from the marine water flea Diaphanosoma celebensis G protein-coupled receptors (GPCRs) are considered to have originated from early evolution of eukaryotic species, therefore, the genome-wide identification of GPCR genes can provide genome, which were classified into five distinct classes (A, B, C, F, and other). Our findings suggest sporadic evolutionary processes within the GPCR gene families identified in D. celebensis
