Аннотация:Maintaining of invertebrates in culture allows to carry out many types of research that appear unavailable in natural conditions.
Cultures of Aurelia sp. (Cnidaria, Scyphozoa) polyps exhibit the dependence between long-term temperature conditions and the sensitivity to the temperature shift inducing strobilation.
Sponge Sycon sp. (Porifera, Calcarea) growth rate depends not only on organic nutrients, but also on regular administration of depleted inorganic salts.
