The purpose of this study was to explore the morphologicalcharacteristics of developing lentiform papilla (LP)in Korean native goats by scanning electron microscopy(SAM). Tongues were removed from fetuses on days 90, 120,neonates, and juveniles on days 30, 60, 90, 120, 150, and 180.In prenatal development, the primordia of LP in 90-day-oldfetuses were round and spotted on the inner most part of thetorus linguae of the tongue. Primordia of LP in 120-day-oldfetuses also had a lens-like shape. In neonates, LP displayedsimilar features as the adult one. In postnatal juveniles ondays 30 and 60, LP continually increased in size withoutmuch difference in structure compared to that of neonates.By postnatal day 90, detached pieces of keratinized superficialepithelia were observed. Microridges and microplicaewere well developed on the epithelial surface of LP in 60-to 120-day-old goats. The lengths of LP were 476~514 μmin neonates, 687~962 μm in the weaning period of 60-dayoldgoats, and 1,068~1,567 μm in the maturing period of180-day-old goats. These findings indicate that goat LP hasdifferent sizes and shapes from those of other species duringdevelopment.
