Rates of development were not completely uniform between individuals, and in some cases a tentacle rudiment formed within 2 days of strobilation
during the ephyral phase.
Scyphozoan polyps typically produce juvenile medusae by the process of strobilation
, which can be induced in various ways.
time about 7 days; easily induced with periods of chilling.
One example is the process of strobilation
in symbiotic scyphozoans such as Mastigias (Sugiura, 1964) and Cassiopeia (Colley and Trench, 1985); these jellyfish produce ephyrae only in the presence of Symbiodinium.
bermudense were ultimately maintained in the endodermal cells and could stimulate strobilation
. Therefore, the s ignals that stimulate phagocytosis could not be the same as those that maintain the symbiosis.
of Chrysaora quinquecirrha polyps in the laboratory.
I counted the total number of exposed zooids on one side of each wedge, the number of those zooids undergoing strobilation
, and the total number of larvae brooded by the nonstrobilating zooids.
