Hematology and serum chemistry data were collected over a 12-yr period for California sea lion (Zalophus californianus) in Everland zoological Gardens. The objective of this study was to determine hematology and serum chemistry values for the California sea lion lived in fresh-water captive environment, including a comparison between male and female. The results didn't show any difference between male and female in statistics. However, hyponatremia was shown in some case compared with reported blood data of California sea lion. That was supposed that it was associated with a fresh-water captive environment.

A 25-year-old female California sea lion (Zalophus californianus) died after a history of depression, loss of appetite, weakness and weight loss. At necropsy, multifocal to coalescing, tan to white, firm nodules, ranging from 0.5 to 3 cm in diameter were observed throughout both kidneys. Renal adenocarcinoma metastasis to the liver, spleen and small intestine was diagnosed based on gross and histopathological findings. To the best our knowledge, this is the first reported case in Korea, and understanding this case will support management and diagnosis of future cases of renal adenocarcinoma in California sea lions.

A case of enetritis caused by Clostridium perfringens was observed in 4years old, male California sea lion(Zalophus californianus). Clinical signs were included in anorexia, depression, diarrhea and vomitting, and the animal died on 4 days after showing clinical signs. Grossly, bloody contents were presented in the intestine and the intestinal mucosa were congested and dark redcolored, and also there were serous fluid in the peritoneal cavity. Histopathologically coagulative necrosis destroyed two third of the villus. Clostridium perfringens were isolated from the intestinal contents. Based on the gross and histopathological findings, this case was diagnosed as necrotic enteritis caused by Clostridium perfringens infection.
