Humans are visual animals and as lucky Australians we love to look at The Great Barrier Reef. This project, while rooted in the complexities of visual neurobiology, uses a recently discovered set of 4 different reef fish from the GBR to teach us more about fundamental principles in vision. These fish, diverse as damselfish and snappers, will help solve a mystery centuries old. Double cones are the commonest daytime photoreceptor in the eyes of almost all vertebrates (humans without them are exceptions) and yet nobody knows what they do. Reef fish have them, so let's ask them what they see!

人类是视觉动物，作为幸运的澳大利亚人，我们喜欢看大堡礁。这个项目，虽然植根于视觉神经生物学的复杂性，但使用最近发现的一组来自GBR的4种不同的珊瑚鱼来教我们更多关于视觉的基本原理。这些鱼类种类繁多，包括小雀鲷和鲷鱼，它们将有助于解开一个长达几个世纪的谜团。双视锥细胞是几乎所有脊椎动物（人类除外）眼睛中最常见的白天光感受器，但没有人知道它们的作用。珊瑚鱼有它们，所以让我们问问它们看到了什么！
