Perivitellins are egg proteins found in the perivitelline fluid of many gastropods. They are multifunctional complexes providing the developing embryo with nutrition, protection from the environment, and defense against predators.[1]
Despite the central role perivitellins play in reproduction and development, there is little information about their role in gastropod Molluscs. Most studies of perivitellins have been performed in eggs of Ampullaridae, a family of freshwater snails (Caenogastropoda), notably the Pomacea genus, mostly those of Pomacea canaliculata, Pomacea scalaris and Pomacea maculata.[2][3]
