Short description Morfologi

Diameter of about 60 cm, exceptionally 90 cm. The sunshade is very bent, sometimes even higher than broad; the periphery is deprived of tentacles, replaced by approximately 80-90 lobes distributed on the entire circumference. One counts 8 very long oral; only braided arms towards their base; and comprising with milonguor of the appendices dermic in the cauliflower shape, while the ends smooth and are not ramified. Color: blue; yellow or pink milky; blue lobes ombrellaires with purple darker.

Biologi     Ordlista (t.ex. epibenthic)

Largest in the Mediterranean, is rather not very irritant: the cnidocytes are slightly poisonous and do not transpierce the human skin; there is thus no risk of lesion. Euryhaline species (Ref. 122857). Found in a river estuary (Ref. 122860) and coastal lagoons (Refs. 81044, 122857). Abundant inshore but also found offshore (Ref. 122861).

Life cycle and mating behavior Könsmognad | Reproduktion | Lek | Eggs | Fecundity | Larvae

Members of the class Scyphozoa are gonochoric. Life cycle: Egg is laid by the adult medusa which later develops into a free-living planula, then to a scyphistoma to a strobila, and lastly to a free-living young medusa.
