Figure 2. Circular map of the complete mitochondrial genome of Thylacodes adamsii.

The complete mitochondrial genome is 14,913 bp in length and contains standard gene components. Of the 37 typical mitochondrial genes, 29 were located in the heavy strand (H-strand; genes named outside the circle) and the remaining 8 were in the light strand (L-strand; inside). The inner circle indicates the GC skew, which is the deviation from the average GC content of the entire mitogenome sequences.

Maximum-likelihood tree showing the phylogenetic position of Vermetidae within Littorinimorpha. Haliotis rubra (Subclass Vetigastropoda) is used as an outgroup. The species examined in this study is presented in a gray box. The GenBank accession numbers of each species are indicated in parentheses. Numbers on the branches indicate nodal support bootstrapping values in percent. Branch supports are inferred from the ultrafast bootstrap method using IQ-TREE web server. The nodes exhibiting BP = 100 and mark an asterisk. The following sequences were used: Littoraria melanostoma NC064398 (Chen et al.
