Snail plots summarising each of the de novo assembled Hydrophis sea snakes. For each assembly, chromosomes are arranged by length clockwise around the circle, with the largest chromosome/scaffold represented by the red segment and line at the start. The dark and light orange sections represent the N50 and N90 values, respectively, while the dark and light blue rings represent the GC and AT content in the genome. BUSCO scores for each genome are presented in the green ring next to each snail plot. Facets represent A H. major, B H. ornatus, C H. curtus (West) and D H. elegans
