Osphradium
As osphradium (of medium Greek ὀσφρἁδιον osphrádion "perfumery"), in the plural osphradia or Spengelsche organs called, refers to an originally twisted-scale sensory organ for aquatic molluscs (Mollusca). The osphradia lie as a thickening of the skin covered with flicker at the entrance to the mantle cavity and are designed as gill-like chemo- and mechanoreceptors .
Some snails find their prey through olfactory perception in the water that flows through the gills. In some mollusc groups osphradia may be fused to an organ or be completely reduced (z. B. Scaphopods (Scaphopoda)).
