| Popis: | Adult female Uca pugilator were allowed to make spontaneous choices during low tide toward lights differing in intensity only. The response patterns for 3010 trials shows that crabs consistently approached the dimmer of two white lights, but if two blue or two red-orange lights were presented, the brighter light was approached more frequently. The responses toward coloured lights disappeared when identical tests were performed at high tide. |
