1. Dugong, 儒艮, 海牛
The dugong ( Dugong dugon) is a marine mammal. It is one of four living species of the order Sirenia, which also includes three species of manatees. It is the only living representative of the once-diverse family Dugongidae; its closest modern relative, Steller’s sea cow (Hydrodamalis gigas), was hunted to extinction in the 18th century.
儒艮（Dugong dugon）是一种海洋哺乳动物。它是海牛目现存的四个物种之一，另外三个是海牛属的物种。儒艮是曾经种类繁多的儒艮科唯一的现存代表，其最近的现代亲缘种是斯特勒海牛（Hydrodamalis gigas），但该物种在18世纪因捕猎而灭绝。
