FIGURE 2 in Morphology and life cycle of Carybdea morandinii, sp. nov. (Cnidaria), a cubozoan with zooxanthellae and peculiar polyp anatomy

FIGURE 2. Longitudunal sections of the polyp of Carybdea morandinii, sp. nov. a) Histological section of the hypostome region; the shutter-lens-like diaphragm was torn off at the right side during sectioning. b) Histological section of one side of the hypostome, showing zooxanthellae in the mouth region (Z) and green-stained mesoglea branching into the shutter-lens-like diaphragm lid (white arrow); C = calyx, Ec = epidermal tissue, En = gastrodermal tissue, H = Hypostome, M = mesoglea, Tb = tentacle base, D = shutter-lens-like diaphragm, Z = zooxanthellae.
