ABSTRACT: The Pseudocyclic (P) integration in modular organisms is determined by specifics in their morphogenesis, ontogeny and systemic features. P-transformations played an important role in the structural evolution of vascular plants. Modular animals are still insufficiently understood in this regard. The pseudocyclic similarities (PS) are found in different taxonomic groups of Coelenterata, Bryozoa, Urochordata. The probability of discovering of other PS increases owing to the hierarchical differentiation of the colony body and network character of structural evolution in different taxa of modular invertebrates. Further frontal analysis of the structural diversity of colonial invertebrates is important from the position of P concept. The results obtained in the analysis of vascular plants are useful in detail examination of the P-integration of modular invertebrates.
