- Аннотация: Aurelia aurita is a representative of Scyphozoa, one of the classes of Cnidaria, the development andlife cycle of which are quite well studied. In recent years, A. aurita has often been used as an object of studying the processes of cnidarian development, including a specific variant of asexual reproduction by strobilation, the formation of ephyrae (jellyfish larvae) due to the transverse fission of the polyp. In most cases, a prolonged decrease in temperature acts as a natural trigger for the initiation of strobilation. The need for prolonged induction and the unpredictability of the result makes it difficult to work with this model object. Therefore, for the induction of strobilation in laboratory conditions, various synthetic chemical compounds, the structure of which is close to that of the alleged “strobilation hormone,” are often used. This paper presents data on the detected deviations in the process of the separation of ephyrae in their external morphology in case of induction of strobilation by 5-methoxy-2-methylindole in A. aurita in laboratory conditions. For the first time, the deviations in the morphology of ephyrae observed in the experiment were compared with the deviations in the morphology of ephyrae and jellyfish from natural populations described in the literature. It is suggested that chemical induction leads to an increase in the frequency of morphological deviations in the ephyrae formed during the strobilation process based on the disorder of spatial patterning and the processes of differentiation of the rudiments.
