| Abstract |
The horizontal (along the coast of the Crimea and partly the Caucasus) and vertical distributions of pyramidellids, their association with certain types of substrates, seasonal dynamics of abundance, size (shell height) of mollusks, and the ratio of the abundance of some Pyramidellidae species to the abundance of their possible hosts were analyzed. Pyramidellidae in the whole are relatively poorly understood in Azov-Black Seas basins. Different species were represented and distributed unevenly. We have noted some species of Pyramidellidae for the first time in a some of places. Thus, the species Parthenina interstnicta was first recorded in the lower reaches and the mouth of the Chernaya River (South-West Crimea) in 2019-2020, as well as in the Donuzlav gulf (West Crimea) in the sandy biotope in the summer of 2020 and so in boulders near Utrish (coast of Caucasus) in 2017. Another species of this genus, P. indistincta , was found on hard artificial substrate in head of the Sevastopol Bay (near Inkerman) in January 2007... |
