Solaster sp. 1 Figure 18E This species was stellate (R/r=~2.1–2.4) possessed a thick disk with nine relatively short, tapering arms. Abactinal paxillae weakly developed, but widely spaced on the surface. Each arm with approximately 20–30 evenly spaced paxillae, per side (40 to 60 from arm tip to arm...
