Aequorin protein needs calcium ions as cofactors as these are only the calcium-activated photoproteins. Bioluminescence is the phenomenon of the emission of bright glowing light from the body of biological organisms due to the various chemical metabolic reactions happening inside the cells. How does bioluminescence in jellyfish work? Other predators include; Ctenophores, siphonophora and other Jellyfish including cannibalism in some cases. if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[300,250],'onlyzoology_com-large-mobile-banner-2','ezslot_11',128,'0','0'])};__ez_fad_position('div-gpt-ad-onlyzoology_com-large-mobile-banner-2-0');It has also been seen that many species can also shine when they detect a predator, possibly making the predator itself more vulnerable by attracting the attention of predators from higher trophic levels.
