DNA sequence analyses: a Neighbour Joining analysis of the 658 bp COI fragment based on p-distances with 1000 non-parametric boostrap replicates. 317 individuals; b Maximum likelihood analysis of the 658 bp COI fragment based on the GTRGamma substitution model with 1000 bootstrap replicates. Numbers on branches represent bootstrap values ≥50 %. Drawings of echinoderms are taken and modified from Hayward and Ryland [56]. A Asteroidea, E Echinoidea, H Holothuroidea
