(11) The regeneration of coelenterate photoproteins in this manner probably takes place in vivo, utilizing stored coelenterazine.
(12) At least 100 of the approximately 9,000 species of coelenterates are dangerous to humans.
(13) Hydra viridis (= Chlorohydra viridissima) the freshwater coelenterate, is symbiotic.
(14) Some years ago our laboratory reported that the bioluminescence reaction in the ctenophores which had long eluded definition involved a calcium activated photoprotein similar in many respects to that found in other coelenterates, notably Aequorea.

(16) Their distribution among lipids of a number of species of different classes of coelenterates from the northern and tropical seas, among neutral and polar lipids of these organisms was investigated.
(17) By using immunocytochemistry and radioimmunoassays, several substances resembling vertebrate or invertebrate neuropeptides have been found in the nervous systems of coelenterates.
(18) Sudden death following coelenterate envenomation is not uncommon in Australia where the Pacific box jellyfish is indigenous.
(19) The principal sources of these agents are bacteria, higher fungi, cnidarians (coelenterates) and the venoms of snakes, insects and other arthropods.
(20) The recurrent eruptions appeared several days after the primary exposure without contact with any offending coelenterate.
