FIGURE 2 in Potential cryptic speciation in Mediterranean populations of Ophioderma (Echinodermata: Ophiuroidea)

FIGURE 2. Examples of morphological variation in Ophioderma longicauda at a size of 15 mm disk diameter. Note differences in the shape (width:length) of oral shields and in the number of arm spines and oral papillae. Ventral disk aspect: (A) brown spm from Marseille; (B) red-brown spm from Cyprus; (C) green male spm from Cyprus; (D) brooding spm from Cyprus, arrow points to juvenile in bursal slit. Arm dorsally: (E) brown spm from Marseille; (F) red-brown spm from Cyprus; (G) green male from Cyprus; (H) brooding female from Cyprus. Arm laterally: (I) brown spm from Marseille; (J) red-brown spm from Cyprus; (K) green male from Cyprus; (L) brooder from Cyprus. SEM images. AS, adoral shield, ASp, arm spine; DAP, dorsal arm plate; LAP, lateral arm plate; OP, oral plate; spm, specimen; TS, tentacle scale; VAP, ventral arm plate. Scale bars 1 mm.
