有鳞状皮肤 - and they are left to fend for themselves...
自从出生的那一刻 - ...from the moment they enter the world.
就要自己保护自己 - But there are differences.
但确有不同之处 - They have a much more efficient breathing system
它们拥有一种更高效的呼吸系统 - that continuously pumps blood across their lungs...
能够持续将血液送至肺部 - allowing them to run without having to stop to catch their breath.
使其在奔跑时无需停下来呼吸
But there are differences. 但确有不同之处
