| [00:00.00] | 这里是活化石的家 |
| [00:02.09] | 一个避难所 |
| [00:03.42] | 鳄蜥一亿多年来几乎没什么变化 |
| [00:07.91] | 全世界近半数的鳄蜥生活在这所避难岛上 |
| [00:12.89] | 在恐龙当道的时代 |
| [00:14.42] | 鳄蜥的祖先无处不在 |
| [00:17.62] | 它们在那场让恐龙灭绝的灾难中幸存下来 |
| [00:21.07] | 但是他们没法和哺乳动物竞争慢慢的灭绝了 |
| [00:24.95] | 除了那块没有哺乳动物的地方——新西兰，是它们能活下去的避难所 |
| [00:29.28] | 鳄蜥不像哺乳动物 |
| [00:30.63] | 它们的生活节奏很慢 |
| [00:34.68] | 许多天过去了，也许他们还没动过身上的任何一块肌肉 |
| [00:37.99] | 有时甚至一个小时只呼吸一次 |
| [00:41.49] | 他们吃沙螽 |
| [00:43.25] | 甲虫和其他无脊椎动物 |
| [00:45.60] | 但是它们不太擅长捕捉这些东西 |
| [00:48.30] | 即使是经过了几百万年的实践 |
| [00:50.65] | 口眼的协调还是不怎样 |
| [00:53.86] | 优胜劣汰”的生活似乎并不适用于这里 |
| [00:58.49] | 鳄蜥的生存 |
| [01:00.15] | 首选新西兰 |
| [01:01.33] | 现在大多集中在斯蒂芬斯岛 |
| [01:02.75] | 这也证实了岛上的生活还是相当安全的 |
| [01:06.81] | 至少可以保证安全直到有其他物种入侵 |
