yet hold a fixed position over the reef
但暗礁上有一个固定的位置
king angelfish make their homes on this reef and they serve as cleaner fish for the Sharks
神仙鱼在这片礁石上安家,为鲨鱼提供清洁的食物
because the Sharks get cuts and scrapes not to mention parasites that need cleaning

they come to a cleaning station where a king angelfish is waiting to clean the wounds and eat the parasites

everyone gets something out of the deal, the angelfish get food and the Sharks get cleaned
每个人都能从交易中得到一些东西——神仙鱼得到食物,双髻鲨得到清洁
the Sharks never eat their cleaner fish that's just considered bad form
双髻鲨从不吃清洁的、形态不好的神仙鱼
a shark looking to be cleaned often swims at an angle with its white belly showing

神仙鱼寻找清洗的对象,双髻鲨在水中上下游动以引起鲨鱼的注意
often something seems amiss to the shark and it rebuffs the fish

the Sharks feel vulnerable while they're being cleaned so they pick a cleaning station carefully
双髻鲨被清洗时感觉很脆弱,所以它在选择清洗站时会很小心
if anything doesn't seem right they move on
如果有什么事情看起来不对劲,它们会继续前进
but patience pays off and eventually the right shark meets up with the right fish in the right place
但是耐心是有回报的,最终对的双髻鲨会在对的地方遇到对的神仙鱼
and everything goes according to plan it's love at first bite
一切都按照计划进行,这属于一见钟情
sometimes a really grungy shark needs a whole team of angelfish to complete the task
有时候,一条邋遢的双髻鲨需要一群神仙鱼来完成这项任务
Darwin Island is one of my favorite places in the whole world to dive

and hammerheads are one of the most beautiful sharks in the ocean

but alas the dive must come to an end and we head back to the surface
