Cross fertilization between sea urchin eggs and oyster spermatozoa
Abstract Interphylum crossing was examined between sea urchin eggs (Temnopleurus hardwicki) and oyster sperm (Crassostrea gigas). The eggs could receive the spermatozoa with or without cortical change. The fertilized eggs that elevated the fertilization envelope began their embryogenesis. Electron m...
