Maximum Likelihood and Bayesian 18S phylogenies of the Enoplia. Maximum Likelihood and Bayesian phylogenies of the Enoplia, outlining major clades within the Triplonchida and Enoplida. (A) Majority-rule ML Tree built using 18S sequence data from 381 taxa, with estimation of the P-Invar parameter and partitions according to 18S secondary structure. Pictograms denote marine (blue drop) and terrestrial/freshwater (green leaf) lineages within the Enoplida. (B) Bayesian tree built using 18S sequence data from 381 taxa, using the GTR+G+I model of nucleotide substitution and partitions according to 18S secondary structure.
