When it comes to capturing colors, animals are ahead of men. Some fish, for example, can see ultraviolet light. The mantis shrimp, which are native to tropical seas, have a better sight than humans. "Mantis shrimp have four times more color receptors than humans. We have three - for red, green and blue - and they have twelve, "explains Justin Marshall of the University of Queensland. Together with colleagues, he researches which colors animals can see and which functions their own color scheme plays. In the journal Science, the two dozen researchers presented the current status of their work. Including Elizabeth Tibbetts, a biologist at the University of Michigan at Ann Arbor. She researches wasps and found out that the heads of Polistes fuscatus, a type of paper wasp from North and Central America, are colorfully patterned. Using these patterns, the wasps can identify with each other and recognize individual conspecifics - quite similar to humans.
