Our analyses suggest that gene gain and loss...The average daily rations of jellyfish varied from one region to another, being the lowest in the Karkinitsky Bay [(0.113 ± 0.10) mg C−1·day−1, or (1.6 ± 2.18) % of C body] with most of the ...Dec 31, 2019 · Jellyfish, members of the phylum Cnidaria, lack any form of cephalization and instead have their neurons distributed in a radially symmetric neural net. In a recent study, upside-down jellyfish ( Cassiopea spp.) were shown to meet all the behavioral criteria for sleep; that is, quiescence, specific sleep posture, reduced responsiveness, rapid ...

(Allen Collins, Smithsonian Institution) In fact, jellyfish aren’t closely related to cephalopods at all (and neither are they closely related to comb jellies, another gelatinous sea-going creature).The discovery of Burgessomedusa gives us a new baseline for calculating the timeline of jellyfish evolution. And it drives home the diversity of Cambrian marine ecosystems, which have the appearance of domination by hard-shelled creatures, as those are more readily preserved as fossils. Instead, they would have been rich and complex, with a ...…
