[27] P. noctiluca will eat small warty comb jellies (Mnemiopsis leidyi), potentially helping to control this invasive species. The luminescent material secreted by Pelagia is inactive in sea water, but when put into salt solutions is activated by some of them. [17], The swimming ability of Pelagia noctiluca is limited and as a result large swarms (also known as blooms) of this oceanic species are occasionally carried by the wind or current to inshore areas, sometimes ending up stranded on beaches.

The behaviour of the oral arms of Pelagia noctiluca (Forsskål) has been investigated in open sea predation and in predation induced both in the laboratory and the natural environment. [19], P. noctiluca are opportunistic and have been recorded feeding on a wide range of small organisms like planktonic crustaceans (cladocerans, copepods, ostracods and crustacean larvae), mollusk larvae, larvaceans, hydromedusae, siphonophorans, arrow worms, fish eggs and fish larvae,[3][7][18] as well as detritus suspended in the open water and microscopic phytoplankton.

Some already reach maturity at 3.5 cm (1.4 in) in bell diameter and at 6 cm (2.4 in) all are mature. Two morphometric indexes were applied: the Gonad-Somatic Index (GSI, gonadal/somatic tissue dry weight ratio) and Fecundity Index (FI, n° eggs mm−2 * gonadal dry weight). In addition P. noctiluca also lacks a gaseous exchange, excretory and circulatory system. [12], This jellyfish is best known from the North Atlantic region, ranging from 4th parallel north (just north of Equator) to the North Sea and Atlantic Canada, including the Mediterranean and Gulf of Mexico.

So, the flower hat jellyfish pretty much looks like someone painted it while tripping on acid. [9] However, it is suspected that Pelagia noctiluca—as currently defined—is a species complex with records outside the North Atlantic region involving other closely related species that presently are unrecognized or undescribed. [7][19][20] On occasion, a swarm may cover tens of square kilometers,[21] include millions of Pelagia noctiluca,[22] and reach densities of more than 500 individuals per m3 (14 per ft3).[18]. Pelagia noctiluca ist eine wahre kleine Nachtlaterne in der großen und tiefen Meereswelt. 45°42′ N) and in June 1986 (Lat. [15] A comprehensive taxonomic review is necessary to resolve the situation.
