The ducks must quickly prise the mussels free before the tide starts to turn. 绒鸭必须赶在潮流转向之前迅速采食
and so provide shelter to those taking their turn in the middle. 以便保护轮流站在中间的企鹅
Now they turn, blasting air from their blowholes, and ascend towards their prey. 现在座头鲸转身 利用呼吸孔吐气 喷向猎物
The sun's rays turn it straight into vapour. 阳光把它们直接变成了水蒸气
These in turn become food for giant cave centipedes, 这些蟑螂也接连成为了 洞穴大蚰蜒的美餐
but it can't turn as sharply as the seal, 但是转向却不如海豹灵活
