Wearing a light blue wetsuit that matches the colour of the sea will make you less likely to become the victim of a shark attack， according to researchers. Sharks are completely colour blind and only see things clearly if they are mostly light or dark， scientists have claimed. In a breakthrough that could prove hugely beneficial to divers navigating shark-filled waters， scientists found that the predator - like dolphins， seals and whales - is unable to distinguish between colours. Costumes or wetsuits that camouflage swimmers' bodies in the sea water are less likely to draw a shark's attention than ones with bright， solid colours than emphasise their outline.

王人说鲨鱼很凶悍，杀东谈主不眨眼，可日前众人做买卖议阐述，倘若身穿“淡蓝色或与海水周边面貌”的泳衣在海底与鲨鱼“亲密交往”，不错大大镌汰被鲨鱼以及鲨鱼群膺惩的几率。据悉，鲨鱼是“色盲”，它们只可看得澄澈深色随机淡色的海底生物，与海水周边面貌的事物一概看不清。此外，科学家还针对其他海底生物进行了商议，比如海豚、海豹、以及鲸鱼等等，这些海中巨兽王人不行永诀海底面貌。科学家提倡，倘若要拍摄鲨鱼在海中生涯情况，不要穿不错在海中“强调形体弧线”面貌的泳衣，深色泳衣、亮色泳衣尽量要幸免。要很好的伪装我方，只须穿连体的和海水相通面貌泳衣就不错了。

Professor Nathan Hart， from the University of Western Australia， said: 'It's the high contrast against the water rather than the colour itself which is probably attractive to sharks.' So you should wear perhaps more muted colours or colours that match the background in the water better.' The researchers examined the eyes of dead sharks and found they had only one type of photoreceptor in the retina， indicating they could only see in monochrome.

来自澳大利亚的素质内森·哈特说：“鲨鱼会对和海水面貌有彰着区别的物体产生兴味夏雨荷 麻豆，是以，与海水相通面貌的泳衣在鲨鱼的眼中不错算是‘隐身衣’了。”据悉，商议员对故去鲨鱼的眼中的视网膜感光性能商议后发现，鲨鱼只可看得见‘单色’，眼中只须能否永诀出单一的视网膜。

The US Navy has conducted tests that suggested sharks were able to see yellow most clearly. The tests had been to see what would be the best colour for the lifejackets that pilots wear in case they have to eject and splash down in the ocean. Professor Hart said it was more the high contrast of yellow， not the colour itself， that would increase the visibility for sharks. He said: 'It may be possible to design swimming attire and surf craft that have a lower visual contrast to sharks and are therefore less attractive to them.' The study by researchers at the University of Western Australia and the University of Queensland， is to be published in the German nature journal Natur wissenschaften (Science of Nature).

好意思国舟师商议发现，最让鲨鱼感到“兴盛”的面貌居然是“黄色”，这个测试是为了发现哪种面貌最稳健作念“浮水衣”。哈特素质说：“并不是因为黄色飘逸而容易被鲨鱼发现，而是黄色与海水的淡蓝色酿成的浓烈反差成果诱骗着鲨鱼。”据悉，这一系列关于海中面貌的商议大大启发了策画海底救生船以及浮水衣的科学家，这些商议将在《德国当然杂志》上发表。
