(16) It's hard not to describe this creature without resorting to multiple similes – it's like a mushroom, an umbrella, a beating heart, an alien lifeform – all of which diminish its glory, as indeed does the word "jellyfish".
(17) This isn’t just about the effect on other species,” said Stefano Piraino, a jellyfish expert at the University of Salento, and one of the 18 signatories.
(18) Jellyfish appear to be on the increase globally, which may be part of a natural cycle or linked to factors caused by humans such as pollution, over-fishing or even climate change, experts said.
(19) Aequorin, a Ca(II)-sensitive bioluminescent protein from jellyfish, emits light at 469 nm from an excited state of a substituted pyrazine (oxyluciferin) which results from the oxidation of a chromophore molecule that is noncovalently bound to the protein.
(20) A new cytolysin has been isolated from the nematocysts of the jellyfish, Rhizostoma pulmo, and named rhizolysin.
Strobilation
Definition:
(n.) The act or phenomenon of spontaneously dividing transversely, as do certain species of annelids and helminths; transverse fission. See Illust. under Syllidian.
Example Sentences:
(1) The cestode either failed to establish or to grow; if the worms were already strobilate when inflammation developed then destrobilation occurred.
(2) Gene expression and its regulation was studied in the rat tapeworm, Hymenolepis diminuta, during strobilization.
(3) In juvenile worms from rats, the extension of the WGA- and SBA-positive region of the strobilation zone increased in length with the development of the worms.
(4) Mongolian gerbils, Meriones unguiculatus, when treated at intervals of 2-6 days with prednisolone tertiary butyl acetate, sustained infection with adult Echinococcus multilocularis in the small intestine, with the tapeworm exhibiting normal strobilation and egg production as in the natural canid host.
(5) Echinococcus multilocularis survived, strobilated and matured sexually in the small intestine of 6-week-old male golden hamsters that were either non-treated or treated with prednisolone tertiary-butylacetate (PTBA), following oral administration of 20 000 protoscoleces.
(6) It is proposed to estimate coefficient of reproduction intensity as the ratio of egg output per unit of time and maximum egg number in a mature strobile.
(7) There were noted differences in of longitudinal trunks in different species and in the specimens of the same species but from different hosts, the width of the strobile being the same.
(8) On the basis of the degree of development of the genital organs zonation of the worm's strobile has been specified.
(9) Scolex growth rate was linear throughout metacestode and adult development, but growth rate in body length was diphasic, punctuated by change of hosts, associated with strobilization.
(10) Phalaropus lobatus from this water body was also infected (13.7) with this cestode, the infection intensity being from 1 to 15 strobiles in one bird.
(11) The number of eggs in strobiles has been estimated for the maturation period.
(12) In experimentally infected puppies, parasite development was noted as follows: strobilation and initial differentiation of the genital primordia on day 7 postinoculation (p.i.

(16) Scolexes of adult cestodes are innervated with 5 pairs of longitudinal nerve trunks, the number of which in the strobile gradually increases up to 17 pairs in species of Eubothrium and up to 60 pairs (in the wildest parts of the strobile) in species of Diphyllobothrium.
(17) Extracts of the strobilate and cysticercus forms of the same species gave identical results.
