Summary of repeat annotations in the four de novo repeat-annotated sea snakes. A-D PieDonut repeat-summaries for the four Hydrophis snakes: A Hydrophis major, B Hydrophis ornatus, C Hydrophis curtus (West), D Hydrophis elegans. The inner circle represents the broad classification, with the outer donut ring consisting of the sub-family percentages. E Distribution of sequence divergence between TEs in each of the four Hydrophis assemblies relative to consensus references. The x-axis is the Kimura 2-parameter sequence divergence estimate, while the y-axis is the percentage of each genome that is annotated as TEs. F Insertion ages of LTR elements in the Hydrophis snakes. The x-axis shows the estimated insertion time (mya), estimated from the divergence level and mutation rate, while the y-axis shows the count of TEs inserted at each time interval
