A: Baikal is the oldest lake in the world and despite the harsh conditions, life flourishes here in isolation. 80% of its species are found nowhere else on Earth, including the word's only freshwater seal. With this seal and its marine-like forests of sponges, Baikal seems more like an ocean than a lake.
貝加爾湖是世界上最古老的湖泊，盡管生存條件惡劣，生命仍在這個與世隔絕的地方得到了興盛。 湖里80%的物種在地球上其他地方都不存在，包括世界上唯一的淡水海豹。有了這種海豹，再加上海底森林一般的海綿，貝加爾湖看起來更像是海洋，而不是湖泊。
