emerge from the safety of their nest deep in the sand. 从安全的沙底洞穴中钻出
that picks up vibrations through the sand, 能够捕捉通过沙子传来的振动
where the sand grains are so perfectly dry and polished, 沙粒干燥光滑的地区
But there are signs on the sand that can give it away. 但沙子的移动 却泄露了它的行踪
but just an inch beneath the surface of the sand, 但仅仅是沙子表面下几厘米处
Scorched by the sun and scoured by windblown sand, 烈日炙烤加之风沙侵袭
sand and gravel carried by the rampaging floods 挟带着砂石的湍急洪水
Marine iguanas lay their eggs in sand. 海鬣蜥将蛋下在沙子里
