Morphological and taxonomic diversity of echinoids included in this study. a Prionocidaris baculosa. b Lissodiadema lorioli. c Caenopedina hawaiiensis. d Asthenosoma varium. e Colobocentrotus atratus. f Strongylocentrotus purpuratus. g Pilematechinus sp. h Brissus obesus. i Dendraster excentricus. j Clypeaster subdepressus. k Conolampas sigsbei. l Current echinoid classification, modified from [6]. Clade width is proportional to the number of described extant species; clades shown in white have representatives included in this study (see Table 1). Colored pentagons are used to identify the clade to which each specimen belongs, and also correspond to the colors used in Fig. 2. Throughout, nomenclatural usage follows that of [6], in which full citations to authorities and dates for scientific names can be found. Photo credits: G.W. Rouse (a, c, e-i), FLMNH-IZ team (b), R.
