纪录片《恐龙的战争》 极限生存(7)(在线收听) |
Luckily, a Tyrannosaurus rex on the hunt is guided by some of the keenest senses in the Cretaceous. 幸运的是,这只狩猎的霸王龙拥有着白垩纪最灵敏的感觉器官。 Its eyesight would actually have been very, very good. 它的视力非常非常好。 The eyes of a T. Rex are huge, the size of cricketballs. 霸王龙的眼睛非常大,相当于板球大小。 A large retina collects more light, more visual information. 巨大的视网膜能收集更多的光线和视觉信息。 So, they can clearly see prey from as far away as 6 kilometers. 因此它们能在六公里外清晰地看到猎物。 Critically, both eyes face forwards, and their line of sight overlaps. 两只眼睛都朝向正前方,它们的视角相互重叠。 So each eye looks at the same object from a slightly different angle. 所以观察目标时每只眼睛的角度略有不同。 That means T. Rex can experience the world in 3D. 这就意味着霸王龙能以立体视角观察世界。 There's very little in the environment of T. Rex that would escape its attention. 在霸王龙所处的环境中没有什么东西能逃过它的眼睛。 For the T. Rex hungry after months of growing her eggs, making a kill may mean the difference between life and death. 对于一头因产子而饥饿数月的霸王龙,一次成功的猎杀关乎它的生死存亡。 Ankylosaurus is a herbivore, but it built like a tank. 甲龙是食草恐龙,但是它却像坦克一样坚固。 Covered in steel-like armor, T. Rex's 3D vision ensures the reptile stands out from the background. 周身布满钢板一样的甲壳霸王龙的三维视角能让其从背景中凸显出来。 T. Rex is impressive and it's powerful, but compare to Ankylosaurus, it is relatively lightly built. 霸王龙强壮有力但是相比较于甲龙,它还是略逊一筹。 Protective plates made of bone and cartilage covered this longberd creature for head to tail. 由骨骼和软骨构成的盔甲从头到尾覆盖在它身上。 Light, but extremly strong, the hide of Ankylosaurus is built like a bullet-proof vest. 质轻,但是非常坚固,甲龙的外壳就像是防弹背心一样。 And most importantly, Ankylosaurus is armed with a deadly weapon. A bony club. 最重要的是甲龙有个致命的武器。骨棒。 If that club were to connect into the skull of the T. Rex, or into the shin and foot of the T. Rex, it will shatter those bones. 如果这根骨棒击中霸王龙的头骨或者胫骨和脚部,将会造成粉碎性骨折。 I think that one good blow by the tail club will be enough to deter this Tyrannosaurus. 我认为这根骨棒要是正中要害足以击退霸王龙。 Ankylosaurus are plant eaters, but that designed to kill. 甲龙是食草恐龙,但是这根骨棒却是用于杀戮。 Even a Tyrannosaurus Rex will struggle to bring one down. 即使是霸王龙也要费尽周折才能制服它。 |
