Hydrophis major is representative of a larger lineage poorly-studied genomically, but subject of intensive collaborative studies of conservation biology, speciation and trait evolution.
Sea snakes are highly marine adapted reptiles that shared a common ancestor with terrestrial Australian snakes only 10-20 million years go. Yet the genomic changes that accompanied their land-sea transition are largely unknown.
