A mammal of the family Otariidae (pinniped) (illustration). It is the largest of the Otariidae. It is hated by fishermen because it causes a lot of damage to the fishing industry. The name "Todo" is derived from the Ainu word "Tondo". It is also called "Kaiba". In the Northern Hemisphere, animals of the Otariidae family are found only in the Pacific Ocean, not in the Atlantic Ocean. Steller sea lions are found in Hokkaido, Sakhalin, the Kuril Islands, the Aleut Islands, the Alaska Peninsula, and the Pacific coast of North America, north of the habitat of the California sea lion and south of the northern fur seal.
