FIGURE 1 in Integrative taxonomy reveals the presence of a new species of Cyanea (Scyphozoa: Discomedusae: Semaeostomeae: Cyaneidae) from the West coast of Africa

FIGURE 1. The only described species of Cyanea from the South Atlantic Ocean—Cyanea annasethe from off the west coast of South Africa. a) whole specimen in anteriolateral view, b) detail of subumbrella surface. Although the colours on Haeckel's (1899) iconic image are not based on observations of a living specimen, the images do impart useful information regarding, inter alia, the distribution of papillae on the exumbrella, the relative depths of velar and rhopalial marginal clefts, the numbers of tentacles, the arrangement of lappet canals, the base of the oral arms and the nature of the radial septa. Note too the endodermal core to the tentacles. Adapted from Plate 8, Haeckel (1899).
