Figures & data
Figure 1. Phylogenetic tree in Sipuncula. The complete mitogenomes is downloaded from GenBank and the phylogenic tree is constructed by maximum-likelihood method with 100 bootstrap replicates. The bootstrap values were labeled at each branch nodes. The gene's accession number for tree construction is listed as follows: Phascolosoma pacificum (NC_031412), Phascolosoma similis (MN813482), Phascolosoma esculenta From Wenzhou(NC_012618), Phascolosoma esculenta From Beibu Bay (MG873458), Sipunculus nudus from France (NC_011826), Sipunculus nudus from Yanta (KP751904), Sipunculus nudus from Gulei (KJ754934), Sipunculus nudus from Beibu Bay (MG873457), and Siphonosoma cumanense (MN813483).
