Catching food in the perpetual darkness is not easy. 在永恒的黑暗中捕捉食物十分困难
Every night, under the cover of darkness they come out to hunt. 在夜色的掩护下 他们每晚都会出来猎食
As darkness falls, animals appear from seemingly nowhere. 夜幕降临 动物纷纷从各处冒出
thrive in the darkness of the forest floor. 在阴暗的森林地面茁壮地成长
resting on the sandy sea floor awaiting the darkness of night, 正在有沙质海床上休憩, 等待黑夜的降临
As dawn approaches, squid and fish and plankton retreat downwards, to shelter in the darkness. 黎明来临, 鱿鱼,鱼和浮游生物再次下沉隐没在黑暗中
another series of hot vents, erupting in the darkness. 另一些在黑暗的海底喷发的火山口
In the darkness, the tables turn. 在黑暗之中 局势发生了变化
