Comparative genomes analyses of B. jamesi and its relatives. A Phylogenetic tree and divergence times of B. jamesi and other arthropods. The number of significantly expanded (+, green) and contracted (−, red) gene families is designated on each branch. B Number of gene families shared among four Malacostraca species shown as a Venn diagram. C KEGG enrichment analysis of the expanded gene families of B. jamesi. The enrichment analysis was performed by using the toolkit from Omicshare (https://www.omicshare.com/). The enriched KEGG terms was referred to the Additional file 1: Fig. S7
