With the tide flooding the tunnel twice a day,
每天两度被潮水淹没
maintenance is a real burden.
地道的维护非常吃力
The tunnel is more than a refuge from the sun,
地道不只能避免日晒
it serves another very important purpose.
还有一个很重要的目的
The tunnel is actually U-shaped
地道其实呈马蹄形
and at the far end is a sealed chamber,
另一头是个密封舱
the walls of which are lined with eggs.
舱壁上是一排排的鱼卵
The eggs are kept in air as it's richer in oxygen than the water.
把鱼卵保存在空气中 因为空气里的氧气比水里多
The problem is the air that's trapped here won't last for long.
问题是保存在这里的空气 维持不了多久
So the male travels to the open end of the tunnel to gulp fresh air.
于是公鱼钻到地道露天的一端 大口吸入新鲜空气
Back he goes down his tunnel where he releases it into the egg chamber.
它回地道去再释放到鱼卵舱里
Replenishing the oxygen on which the eggs depend.
补充鱼卵赖以维生的氧气
He will repeat this hundreds and hundreds of times
这个动作将重复数百次
until his young hatch.
直到小鱼孵化为止
This lifestyle is very demanding,
这种生活方式非常辛苦
yet the mudskipper has found a way around every problem.
然而弹涂鱼碰到任何问题 都有办法解决
