Osphradium

As osphradium (of osphrádion medium Greek " fragrant bouquet ", " perfumes " ), called in the plural osphradia or Spengelsche organs, refers to a scale originally paired sense organ in aquatic molluscs ( Mollusca ). The osphradia are as a flicker -covered skin thickening at the entrance to the mantle cavity and are designed as gill -like chemo-and mechanoreceptors.

Some snails find their prey by olfactory perception in the water which flows through the gills. In some mollusc groups osphradia may be fused to an organ or completely reduced (eg Kahnfüßer ( Scaphopoda ) ).
