In a harbor seal in captivity from the Yellow sea of Korea, alopecia began on flippers and tail, and spread to ventral part of abdomen and dorsal part of body in order. Multiples coalesced, and well-circumscribed lesions such as patches and maculas appeared on foreflipper, hind flipper, perianus, ventral part of tail, lips, and some parts of trunk were appeared in. Phialophora richardsiae, Gemella morbillorum, and coagulate-negative etaphyococci were isolated from Besions and hairs. After treatment with internal and external ketoconazole, povidone iodine, cephalexinl Pink Skin~l and multivitamins hair grew up and lesions were disappeared completely 8 months after occurrence.

A male harbor seal (Phoca bitulina) about 10 years of age died. The seal was presented for necropsy in the Veterinary Teaching Hospital, Chungbuk National University in August 2001. The seal had been a concrete pool in zoo for 4 years. The exact duration of captivity was unknown. The carcass was weighed about 90 kg and was about 140 cm length. At necropsy, 2 adult filarioid worms were found in the right and left ventricles. The filaroid worms weren't found in the other organs. The parasites were slender white nematodes. A male nematode in the right ventricle was 14 cm long, and a female nematode in the left ventricle was 26 cm long in length. The parasites were identified as Dirofilaria immitis.

An acanthocephalan parasite, Corynosoma strumosum, was found in the intestine of harbor seal, Phoca largha, living in the East Sea, Korea. The probosci's hook and trunk spine patterns typical of the collected worms indicated it to be C. strumosum. The body lengths measured are 4.2-5.8 (4.9) mm in males and 5.3-6.8 (5.7) mm in females. The proboscis is bent ventrally, armed with 18 longitudinal rows of 9-13 hooks in males and 20 longitudinal rows of 11-13 hooks in females. The proboscis receptacle is double-walled with the robust trapezoidal neck being unarmed. The hind-trunk is pipe-shaped with posterior parallel sides. The characteristic hind trunk spines cover the anterior third of the ventral surface. The lemnisci are equal and slightly shorter than the double-walled proboscis receptacle, which is longer than the proboscis. This species is an acanthocephalan parasite reported for the first time in Korea.
