Abstract
Feeding selectivity of rapa whelk, Rapana venosa (Valenciennes, 1846) on mussels Mytilus galloprovincialis Lamarck,1819 was estimated by the caging experiment in the coastal waters of the Zmeinii Island (north-western Black sea) in summer 2012. For 17 days the size, morphological and phenotypic characteristics were revealed in shells of eaten and living mollusks in cages. The mussel phenotypes were revealed on color of outer prismatic layer of shells and also on interrelation of prismatic and nacreous shell layers in the ligament area. The shells of eaten mussels were differed from the shells of mussels which remained living by length, height, width, shell mass/surface−area ratio.
