Bathers retreat from the water if they, The evolutionary patterns associated with strobilation and life‐cycle type have not been thoroughly investigated, and many studies of ephyra development and strobilation induction are not yet synthesized. Herein, I place the development of scyphomedusae in an evolutionary context. I first review the current evolutionary hypotheses for Scyphozoa..

It has been suggested that Aurelia is the best-studied group of gelatinous zooplankton, with Aurelia aurita the best-studied species in the genus; two other species, Aurelia labiata and Aurelia limbata have also been

Scyphozoa include the moon jelly Aurelia aurita, in the order Semaeostomeae, and the enormous Nemopilema nomurai, in the order Rhizostomeae, found between Japan and China and which in some years causes major fisheries disruptions. The jellyfish fished commercially for food are Scyphomedusae in the order Rhizostomeae.

Oct 18, 2012 · Following the excystment experiments, the cuticle covering unexcysted podocysts was artificially removed with a dissecting needle, in order to examine whether the naked cell mass would transform into a polyp or not (Black et al., 1976; Ikeda et al., 2011).In addition, a similar cuticle removal was applied to 10 podocysts at each of various ages (1, 2, 4 and 6 years old) that had remained

Under constant temperature (22 В°C) and a low-food regime (2.4 Ојg C polyp в€’ 1 d в€’ 1), the effect of salinity was examined by placing polyps individually in 6-well plates containing seawater of 7 different salinities (5 polyps at each level, Table 1) for 8 weeks.The cumulative numbers of podocysts produced in different salinities were analyzed with one-way ANOVA.

Comparative physiologists examine them as possibly simple models for the functioning of various systems. This book integrates data from those and other investigations into a functional biology of scyphozoa.

Scyphozoa have attracted the attention of many types of people. Naturalists watch... Massive proliferations of scyphozoan jellyfish considerably affect human industries and irreversibly change food webs. Efforts to understand the role of jellyfish in marine ecosystems are based on a life cycle model described 200 years ago. (628K, pdf) Acknowledgments. Arai M. N. A functional biology of Scyphozoa.
