title: Early morphogenesis of metacercariae of trematodes Paratimonia sp. Prevot and Bartoli, 1967 in gastropods Hydrobia acuta (Draparnaud, 1805) in the Black Sea environment
abstract: The purpose of the research is studying the morphology of larvae of Trematoda Monorchiidae of the genus Paratimonia and establishing possible causes of their accelerated morphogenesis. Materials and methods. The material for this study was trematode larvae (metacercariae) from 283 specimens of gastropods Hydrobia acuta that we collected in March 2012 at the estuary of the River Chernaya (Sevastopol, the Black Sea, 44°27′49″ N 33°51′37″ E). The gastropods were studied for helminths using the comp
