title: Morphogenesis of the olfactory pit in a flatfish, barfin flounder (Verasper moseri).
abstract: Morphogenesis of the olfactory pit (OP), olfactory lamella (OL) and olfactory epithelium (OE) was examined by scanning electron and light microscopy in the barfin flounder (Verasper moseri). At day 0 after hatch, the OP was already formed. At day 14, the cellular differentiation of the OE was prominent. At day 42, the OP became a cavity by the formation of its roof. At day 56, the first OL extended remarkably and was lined with the OE on both sides. The OL increased in number with development. These findings suggest that the OE is functionally active at day 14. The formation of the OL in the OP may be initiated by the stimulus when the barfin flounder touched at the bottom of the sea.
