Soon each hippo is trailed by a shoal of fish,
没多久 每只河马都有鱼群尾随其后
waiting for their breakfast.
等着大啖早餐
Hippo droppings.
河马的粪便
But it's not just the hippo's dung the fish are interested in.
但鱼儿凯觑的不只是河马的粪便
When the hippos reach one particular spot in the pool,
当河马来到水潭的某个地方
they stand still and wait.
就站定等候
And the fish start to clean them...
鱼儿开始为它们洁净身体
..removing ticks, parasites and other tasty morsels.
解决虱子和寄生虫 和其他美味的食物
To the fish the hippos are a mobile cafeteria.
河马是鱼类的活动自助餐厅
The hippos seem to be enjoying the sensation.
河马似乎很享受这种感觉
The only thing that interrupts the feast
河马偶尔要吸口气
is the need to take an occasional breath.
唯有这时才会打断这场飨宴
