- With the tropical shallows gone,
热带浅海消失了 - the few survivors were those who could head to deeper waters.
能够前往更深水域的生物 成为了少数的幸存者 - Animals like the nautilus,
比如鹦鹉螺 - a smaller relative of the giant Cameroceras.
巨大的房角石的小个儿亲戚 - It first evolved hundreds of millions of years ago,
最早在数亿年前进化 - but still exists today.
但如今依然存在 - It owes its success to the deep ocean's unchanging nature.
它的成功要归功于深海的稳定性
