Eschscholtz, 1829

Diameter recorded up to ca. 25 cm. Exumbrellar surface thickly covered by minute truncate papillae. Tentacles up to 40 in adult, each octant having 5 tentacles, a central primary tentacle (forming earliest and being largest until adult size is reached), two secondaries slightly smaller or same size (?depending on age) laterally, and two, smaller, tertiaries in the spaces between the primary and secondaries, all arising from clefts between lappets. Clefts between tentacular lappets not uniform in depth, those of tertiary marginal tentacles being shallower than those of secondaries, and those of primaries still shallower (see Chrysaora lactea 2); oral arms V-shaped in section, edges slightly frilled, terminal region possibly spiral (data scant). Stomach pouches uniform in width. Radial septa narrow, some widening at inner end either gradually (as in Chrysaora hysoscella), or abruptly with pear-shaped outline (as in Chrysaora plocamia but not so widely).
Coloration little known, so far recorded as uniform, ranging from pale milky-white, or with weak purplish tint, or pale lilac. Brownish-red radial lines, spots and patches on exumbrella recorded in some populations (Mayer, 1910; P.F.S. Cornelius, pers. obs.). Marginal tentacles colorless, once pale reddish-purple (Eschscholtz, 1829). Mouth arms and subumbrellar ostia spotted dark brown.
Sting mild, lasting 30-60 minutes (P.F.S. Cornelius, pers. obs).
