All cnidarians are thought to possess two tissue layers: endoderm and ectoderm, which are separated by mesoglea in medusa. The determination of the composition of the Aurelia aurita jellyfish mesoglea was performed. A new protein “mesoglein” was determined as one of the main components of mesoglea. Deduced amino acid sequence of mesoglein contains the Zona Pellucida (ZP) domain and DSL domain. Antibodies against mesoglein stain the plate in the place of contact of germinal epithelium and oocyte. The structure found was named the “contact plate”. The contact plate could be the precursor and functional analogue of the ZP.
