Taranto spider is a formidable animal, but some wolf spiders are more festive than people think – in fact, some have bright blue and green colors. In a new study, published in the proceedings of the Royal Society B, scientists have found that the once considered color blind wolf spider, haplopelma lividum, can actually sense certain colors. This does not necessarily mean that tarantulas can see all kinds of colors, but it has important implications for the hypothesis that some tarantulas have evolved such bright colors in order to attract their mates. < p > < p > researchers from Yale National University College of Singapore and Carnegie Mellon University believe that blue may be used to attract potential mates and “communicate” with them, while the green color of some tarantulas may be used to camouflage and hide in arboreal or tree dwelling species. < / P > < p > the team investigated the body expression of photosensitive proteins in the eyes of tarantulas to determine whether they have comprehensive color perception. The results show that although they may not have a complete spectrum, they can certainly sense the blue color that haplopelma lividum has evolved – and, by comparative phylogenetic analysis, scientists have concluded that they are probably born blue, millions of years old. Saoirse Foley, CO chief scientist at Carnegie Mellon University, stressed that while these conclusions are based on data, there is still room for further confirmation. “Although the exact function of blue is still unclear, our results suggest that tarantulas may be able to see these blue displays, so mate selection is a potential explanation,” she said. < / P > < p > “we have set a momentum for future projects, including behavioral elements, to fully explore these assumptions and to consider how to build on our results for further research is very exciting.” Global Tech
