Larvae of Nassa largely contribute to plankton and adults to benthos, where, like other molluscs, they are common prey for fish of Labridae family. In the early XX century it was found that some N. reticulata from the Black Sea were infested with cercariae and metacercariae of Cercaria inconstans (Sinitsin, 1911), later re-identified as Diphterostomum brusinae Stoss (Palombi, 1930) adults of which are known to parasite fishes of families Labridae, Blennidae, and others. In the Mediterranean Sea parasitic fauna of N. reticulate has not been studied. At present (1964) it is known that Nassa reticulate harbours six cercaria larvae: Cercaria sagitata Lespès, 1857; C. hymenocerca Villot, 1875; C. fascicularis Villot, 1875; (C.) Diphterostomum brusinae (Stoss., 1889) Stoss., 1904; Cercariaeum reticulatum Stunkard, 1932 and unidentified rediae with furcocercariae.ru
