Fig. 9From: Symbiotic association between Solanderia secunda (Cnidaria, Hydrozoa, Solanderiidae) and Medioantenna variopinta sp. nov. (Annelida, Polychaeta, Polynoidae) from North Sulawesi (Indonesia) Medioantenna variopinta sp. nov. a–c. Underwater photographs of M. variopinta sp. nov. on unfertile S. secunda colonies (Photo Massimo Boyer); the polychaete is more evident when hydroid lacks the orange gonophores (a–b) or the hydranths (c). d, e. Stereomicroscope pictures of fertile specimens of S. secunda hosting M. variopinta, the worm livery perfectly mimics the host colors. White arrows: hydranths; black arrows: gonophores.
