Hitherto, several studies have already focused on the anti-infection immunity and stress response of M. cephalus (Waltham et al, 2013;Byadgi et al, 2016;Li et al, 2017), including the strategies for different kinds of infection, hypoxia, extreme osmotic pressure, heavy metals, and toxicants. The expansion of gene families related to immune response and sodium channel activity indicated that the source of environment adaptability of M. cephalus could be used as potential candidates during subsequent studies.…”
