Schematic diagram of A. fuscoviridis and its retractor muscle. (a) Longitudinal section of the sea anemone showing the paired mesenteries that partition the gastric cavity. The free edge of the mesentery below the pharynx contains the gonads and filaments. The longitudinal retractor muscles are located on one side of the mesentery. (b) Detailed illustration of a cross-section through a mesentery. A mesentery is composed of two gastrodermal layers, one containing the longitudinal retractor muscles. The mesoglea ramifies within the retractor muscles. M, paired mesenteries; RM, retractor muscle; Epd, epidermis (ectoderm); Gsd, gastrodermis (endoderm); MG, mesoglea; Gn, gonad; Mf, mesenterial filament.
