日本海狮
日本海狮（Zalophus japonicus）是已灭绝的海狮。于2003年前，日本海狮都被认为是加州海狮的亚种，但后来有指日本海狮与加州海狮有不同的栖息地及行为，故被分类为独立的物种。
日本海狮栖息在日本海，尤其是在日本列岛及朝鲜半岛的近岸地区。牠们一般会在开放及平坦的沙滩上，甚至有时亦会在石上繁殖。
现时在日本及荷兰有几个日本海狮的标本。而在大英博物馆则存有日本海狮的毛皮及4个头颅骨。

The Japanese sea lion(Japanese:ニホンアシカHepburn:Nihon ashika, Zalophus japonicus) is an aquatic mammal thought to have become extinct in the 1970s.
Prior to 2003, it was considered to be a subspecies of California sea lion as Zalophus californianus japonicus. However, it was subsequently reclassified as a separate species. Some taxonomists still consider it as a subspecies of the California sea lion. It has been argued that Z. japonicus, Z. californianus, and Z. wollenbaeki are distinct species because of their distant habitation areas and behavioral differences.
