A male pup Kuril seal (Phoca vitulina stejnegeri) from Hokkaido, Japan, was observed with a unilateral and total cleft of the primary palate. Complications included a supernumerary tooth, hypoplasia and asymmetry of the face, and deformation of the eyeball and external auditory meatus. An accompanying pneumonia may have resulted from water flowing into the respiratory system due to imperfect closure of the nostril by the cleft. No other abnormalities were found.
