Aquatic eye design: sharks and rays as models of underwater colour and luminance vision.

鲨鱼通常被认为是色盲。我们已经发现，它们实际上可以很好地识别颜色，而且不同物种的眼睛也适应了它们特定的生活方式。我们的研究将有助于提高鲨鱼的形象，并将它们描绘成具有先进感官系统和复杂视觉行为的动物，而不仅仅是危险的杀戮机器。研究鲨鱼的视力也可能有助于减少澳大利亚长线渔业每年捕杀的副渔获物数量（目前约为50万），并为管理和保护我们的生物多样性做出有价值的贡献，这是澳大利亚国家研究重点之一（澳大利亚环境可持续发展）。

Sharks are usually assumed to be colour blind. We have discovered that they may in fact see colour very well and that the eyes of different species are adapted to their particular lifestyles. Our research will help to raise the profile of sharks and portray them as animals with advanced sensory systems and complex visual behaviours rather than just dangerous killing machines. Studying the vision of sharks may also help to reduce the number (currently >50,000) that are killed each year as bycatch by Australian long-line fisheries and make a valuable contribution to one of Australia's National Research Priorities (an Environmentally Sustainable Australia) for managing and conserving our biodiversity.
