A curious-looking spider was preserved in amber that was 50 million years old found in 1854. With an elongated neck-like structure and long mouth parts that assume to form the “head” like angled edge.   So far large number of spiders are unstudied due presence of remote parts of the Earth.  Pelican spiders are active hunters, prowling the forest at night and following long silk draglines that lead them to their spider prey. When a pelican spider fnds a victim, it swiftly reaches out and impales it on its long, fang-tipped “jaws,” or chelicerae. Then it holds the spider away from its body, keeping itself safe from potential counterattacks, until the victim dies. In addition to Madagascar, modern-day  pelican spiders have been found in South-Africa  and Australia  All of the pelican spiders that Wood described  live only in Madagascar, an island whose tremendous biodiversity is currently threatened by widespread deforestation.

Nature is full of wonder. Every specie has its own value on the Earth. No one can deny it. As a marvelous creature named Chameleons has.  Chameleons  are famously known as altering their skin color. Munich in Germany have now discovered that the bony tubercles on the heads of many  species also glow under ultraviolet light and form decent pattern. F luorescence produced by living creatures is mainly known from marine organisms  but is rare in terrestrial  vertebrates.  We could hardly believe that our eyes are illuminated by the Chameleons on the striking of UV lamp. To obtain better result researcher use variety of latest methods. Scans shows that  the skin covering the tubercles on the skull is very thin and consists only of a transparent layer of  epidermis . " These patches effectively act as channels that transfer the  UV light to the bone, where  it is absorbed and then emitted again as  blue fluorescent light.” Ad...
