Abstract

This article presents the results of the study of Anadara kagoshimensis shells collected on the coast of the Azov-Black sea region. The studied species, which was indirectly introduced in the late 1960s, is a resident species for this water area, which makes it particularly relevant to study the biology of the species in question in a new habitat. During the research, the morphological analysis of the shells of 777 individuals of the mollusk species in question, samples of which were collected in the period from 2008 to 2019, was carried out. As a result of research, the main types of deformations of shells were identified. kagoshimensis and their geographical distribution in the Azov-black sea water area. The most widespread forms of pathological changes were the moves of polychaete perforators (genus Polydora) and the defeat of the parasitic fungus Ostracoblabe implexa.
