title: CLARIFICATION OF MORPHOLOGY AND ECOLOGY OF TWO SPECIES OF THE GENUS PECTENOGAMMARUS REID, 1940 (GAMMARIDAE, AMPHIPODA) FROM THE BLACK AND AZOV SEAS (CRIMEA)
abstract: The researchers studied the morphology and ecology of two species from the genus Pectenogammarus – Pectenogammarus olivii (H.Milne Edwards, 1830) and Pectenogammarus foxi (Schellenberg, 1928) from the Black and Azov Seas coasts of Crimea. It is found that the species P. foxi prefers pebble-sandy beaches, and the species P. olivii prefers rocky and rocky-boulder beaches. Morphological analysis of P. foxi and P. olivii shows that the differences in spines or setae between these species relate prim
