Embryology and development of the snail,
Melania scabra was studied. The embryos complete their development in a special incubatory pouch called the broodpouch and hatch out in a form completely resembling that of the adult. The embryonic development of the snail represents specialized features like precocious development of the statocyst, presence of a well developed velar retractor muscle and torsion.
