38 m depth, Punta Bianco, Corse, Mediterranean Sea, Aug. 1981, dorsolateral view of 8 mm specimen, Photo: C. Huygens (Brunckhorst, 1993: Plate 5D).

Notes compiled from Brunckhorst, 1993:
The pale cream dorsum with its fine, pale brown, mottled pattern sets F. bayi apart from all other Fryeria species. The dorsal intestinal sac is also unique to this species.

Fryeria rueppelii, Fryeria guamensis, Fryeria menindie and Fryeria marindica all have a black background, gold-yellow capped tubercles and gold rhinophores (pale cream in F. bayi). Fryeria larryi is closer to F. bayi, but it has yellow coloration (no brown pigmentation) and is not mottled. In contrast, F. larryi possesses a few red, transverse lines which occur laterally.

Note: See message discussing whether this species should be in the genus Phyllidiopsis.
