Figure 2. Mitochondrial genome map of Ophioleila elegans. GC content was plotted by default values of window size (500) and score scale (1).

Figure 3. The maximum-likelihood (ML) phylogenetic tree of Ophioleila elegans and other ophiuroid species based on 13 protein-coding mitochondrial genes. Numbers on each node denote the bootstrap support values from the ML and the Bayesian posterior probabilities from the Bayesian inference (BI) method. The scale bar indicates the number of substitutions per site.
