Figure 2. Stichodactyla haddoni. A) CHIAS2 in situ (Ex: exocoelic tentacles are seen at the edge of the oral disc; En: endocoelic tentacles). B) CHIAS2 in aquaria. Note the coloration, tentacles, and red oral disc. The density of tentacles is lower near the mouth. C) Aboral view of CHIAS2: arrow shows the row of nonadhesive verrucae (V). The diameter of the oral disc is much broader than that of the pedal disc. Scale bars: 8 cm for A and B, 6 cm for C. Photo A: Mohammad Bahman; Photos B and C: Pegah Javid.
