Up to 8 cm wide, usually hemispherical, exumbrella with very fine granulations; gelationous substance firm; deep furrows between the 8 velar lappets (in each octant); mouth-arms about half as long as bell diameter, the simple upper portion one and a half times as long as the three-winged lower portion; each arm usually, but not always, terminates in a club-like filament, triangularin cross-section; numerous small, club-shaped cesicles between mouths; less than 10 canal-roots in each octant; rhopalar canals clender, usually with anastomoses.
Mostly in shallow waters during the day to allow its symbiotic zooxanthellae (where it derives its energy from) to bathe in sunlight. Mainly solitary. As the sun mainly influences its habits, it descends to lower parts of the water column when the sun sets. It gathers food such as zooplankton, phytoplankton, small invertebrates, and microbes using the oral arms of its mouth (Ref. 101744).
Life cycle and mating behavior
পরিপক্কতা | প্রজনন | ডিম ছাড়া | Eggs | ডিম্বধারন ক্ষমতা | 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.
