Strobilation in the chesapeake bay sea nettle, Chrysaora quinquecirrha—II. Partial characterization of the neck-inducing factor from strobilating polyps

Comparative Biochemistry and Physiology A, Comparative Physiology, 1974
Abstract 1. 1. A neck-inducing factor (NIF) is involved in initiation of strobilation in Chrysaora quinquecirrha polyps. NIF induces formation of a neck under the tentacles, evidence that strobilation has begun. 2. 2. NIF is detected in the medium approximately 2 hr after chilled polyps are stimulated to strobilate by raising their ...

Optimising the application of 5-methoxy-2-methyl-indole to induce strobilation in moon jellyfish polyps

Marine Biology, 2020
Indoles, including 5-methoxy-2-methyl-indole (5MeO2MeIn), are a potent trigger of strobilation in jellyfish polyps. Indoles may be an alternative method to cooling to induce strobilation, but the ephyrae produced should have similar or better rates of ...

Light as an Inhibitor of Strobilation in Aurelia aurita

Nature, 1964
THE environmental conditions under which strobilation of Aurelia scyphistomae occurs are incompletely understood. Berrill1 in a review suggests three factors as being of particular significance: a heavy diet of suitable food prior to metamorphosis; a definite, low critical temperature, usually the winter minimum; and a good supply of food and oxygen at

Standardization of strobilation in Phyllorhiza punctata

, 2020
In recent years many large aquariums have added a variety of jellyfish to their collections, and as a result the market for these individuals has substantially grown, leading to an increase in their price. This has led to a rising interest in the reproductive biology of such creatures, and in the convenience of studying aquariums in order to reproduce ...

A study of strobilation in Aurelia aurita under controlled conditions

Journal of Experimental Zoology, 1965
AbstractThe maintenance of Aurelia aurita polyps in this laboratory has made possible the study of strobilation under well controlled laboratory conditions for the first time. The development of pulsing, statocysts and gastric filaments during normal strobilation occurring in artificial sea water at constant temperature was observed.
