1928年，哈特兰注意到马蹄蟹（Limulus polyphemus）的侧眼为视觉生理学研究提供了令人钦佩的准备。从那时起，对limus的广泛研究产生了对视觉过程和一般感觉过程的基本理解1,2。然而，除了证明了原始的趋光性3 - 5之外，研究尚未揭示视觉在动物行为中的可能作用。我们通过研究交配行为进一步调查了这个问题，交配行为是limusus在其自然栖息地中唯一已知的行为。我们在这里报告说，在交配过程中，马蹄蟹区分形式和对比：雄性会被雌性甲壳的彩色水泥铸件和其他形式所吸引，吸引的程度取决于铸件的形式和对比，以及一天中的时间。形式的辨别可能是由多个感觉系统传递的信息产生的，但对比的辨别需要视觉。
In 1928 Hartline noted that the lateral eye of the horseshoe crab,Limulus polyphemus, was an admirable preparation for research in visual physiology. Since that time, extensive studies ofLimulushave yielded fundamental understandings of visual processes and of sensory processes in general1,2. However, except for demonstrations of primitive phototaxis3–5, studies have not yet revealed a possible role of vision in the animal's behaviour. We have further investigated the problem by studying mating behaviour, the only known behaviour exhibited byLimulusin its natural habitat. We report here that horseshoe crabs discriminate form and contrast during mating: males are attracted to painted cement castings of the female carapace and other forms, the degree of attraction depending on the form and contrast of the castings, and on the time of day. The discrimination of form may result from information transmitted by several sensory systems but the discrimination of contrast requires vision.
