FIGURE 5 in Redescription of Mastigias papua (Scyphozoa, Rhizostomeae) with designation of a neotype and recognition of two additional species

FIGURE 5. Adult Mastigias papua medusa (103 mm bell diameter) from the type locality: waigeo, west Papua (specifically from Mastigias Papua Cove). A. Profile view of M. papua, with details of the oral arm and margin of the bell. Two rhopalia are marked with arrows, delineating an octant. B. Details of the subumbrellar view of the terminals clubs, showing the typical 'tricorn' cross-section of lagoonal animals. C. Details of the contracted bell margin and oral arm. Note the patches of endosymbiontic zooxanthellae (here most easily visible as tan tiny dots in the unwinged part of oral arm). D. Subumbrellar view of canals dyed in the laboratory, note the perradial canal (p) and the interradial canal (i) which are both generally simple canals originating at the gastrovascular cavity and ending at the ring canal; the origins of the highly anastomosing adradial canals are marked with yellow circles where they join the gastrovascular cavity. E. Subumbrellar view of the bell margin, with velar lappets in between the two pairs of rhopalar lappets (r).
