Aim . The question of life forms (morpho-ecological adaptation of the organism to the environment) is an actual problem of ecological morphology. Different approaches in the study of Coleoptera life forms, including comparative morphological, ontogenetic and ecological faunal approaches, have identified the main trends of the morpho-ecological evolution of the studied fauna, and the spectrum method of life forms helped find out the laws of their landscape-zonal distribution. Methods. Electron microscopy scanning was performed at the Institute of Arid Zones of the Southern Scientific Center of RAS (Rostov-on-Don), using a microscope SEM EVO-40 XVP (LEO 143OVP). Results. In this article, for the first time, the life form to be used for some reconstructions of the fauna of the age of certain ecosystems of the discussed territory. In this paper, morphological adaptation of the feet is considered closely related to the features of lifestyle and environmental conditions, mainly the soil. The structure of the feet of Tenebrionidae is closely related to their living conditions and patterns of behavior. Convergence in the structure of the feet of phylogenetically distant species is the result of a match in their evolutionary development of the living conditions and behavioral characteristics. The structure of fossorials (digging legs) of Tenebrionidae and Scarabaeidae is in a thin line with a certain type of soil conditions. As a result, among the examined groups of Coleoptera the structure of fossorials is the most reliable indicator of soil conditions. The analysis of the biological diversity of coastal and island ecosystems of the Caspian Sea has shown the failure of the existing reviews for Caspian water level regime and the age of biota of islands. Conclusion. Thus, the presence of the ancient highly specialized life forms, communities and systems in any particular area, with great certainty will allow conceding the continuity of the existence of this biota during the time required for the formation of structural units of the community, the individual species, subspecies and supra species taxa. The analysis of the life forms of individual taxonomic groups, species, communities, modern biological diversity of coastal and island ecosystems does not confirm the periods of "strong" transgressions flooding vast areas of the Caspian and the islands of Turan. They contradict these assumptions.
