Description
FIGURE 3. Radiolar crown in Spirobranchus bakau sp. nov. specimens. A—Top view of radiolar crown in paratype (ZRC. ANN.0482), showing circular arrangement of radioles; B, D—Radiolar crown with alternating black and cream-coloured bands at the base. The translucent, free ends of the radioles take on the colouration of underlying golden-brown pinnules. Red pigmented spots are mostly arranged in pairs on each radiole; C, H—Lateral views of complete holotype of S. bakau sp. nov. (ZRC.ANN.0480). Image was taken prior to excision of posterior abdominal segments for molecular studies. Evidence of sperm release in C (white arrow), indicating that the specimen is a male; E—Greyish bands alternating with black bands at base of radioles; F—Pinnules near tips are of brownish colouration; G—Distal end of radiolar base in paratype (ZRC.ANN.0481) with peach colouration (white arrow), which extends into inter-radiolar membrane. Scale bars—A–B, D–G: 0.5 mm, C, H: 1 mm.
