Fig. 2 in A newly recorded brittle star, Amphiura (Amphiura) digitula (H.L. Clark, 1911) (Ophiuroidea: Amphilepidida: Amphiuridae), from Geoje Island, Korea

Fig. 2. Neighbor joining (NJ) and maximum likelihood (ML) trees based on 657 bp of the mitochondrial COI gene from 21 Amphiura species, including A. (A.) digitula. Bootstrap support values indicated on each node. (A) Phylogenetic tree of neighbor joining based on the kimura 2-parameter distance model, with 1000 non-parametric bootstrap replicates; (B) phylogenetic tree of maximum likelihood based on the GTR + I + G model, with 1000 bootstrap replicates.
