Severtsov Institute of Problems of Ecology and Evolution, Russian Academy of Sciences, Moscow, Russia aut Comparative analysis of Rapana venosa (Valenciennes, 1846) from different biotopes of the Black Sea based on its morphological characteristics [Elektronische Daten] [A. Kos'yan] The Asian whelk Rapana venosa (Valenciennes, 1846) (Gastropoda: Neogastropoda: Muricidae), being tolerant to wide variations in the temperature, salinity, and oxygen concentration, successfully settled down in the Black Sea and eventually became one of the dominant species in the benthic ecosystems. The whelk inhabits all types of grounds all over the Black sea demonstrating a wide spectrum of morphological modifications. The objective of this research is to compare 10 samples of R. venosa from different biotopes of the Black Sea coast from the western Crimea to Sochi. The results of the statistical comparison based on 15 morphological characteristics showed that most of the samples differed from each other with high statistical significance (p < 0.001). The material fell into five groups on the discriminant analysis diagram corresponding to the biotope in which each was collected. The main ecological factor influencing the morphological variability of the rapa whelk populations is the characteristics of prey items they feed on, i.e., the bivalve species (Mytilus galloprovincialis, Anadara sp., Chamelea gallina), the prevailing prey size, and its abundance.
