Spiders evolved into unusual electro-optical blue

A rare tarantula spider has an electrolytic green color and scientists do not yet understand why its body evolved into this color.

Daniel Valcarcel, a medical student in Barcelona, ​​Spain, shared the video of the tarantula spider of Poecilotheria metallica crawling through the arm on Viral Hog's page on September 22, according to Sun.

In the video, the spider is electrically green with white stripes crawling back and forth on the man's hand. According to the International Union for Conservation of Nature's Red Book, spider Poecilotheria metallica lives only in an area of ​​100 square kilometers in India and is in an extremely dangerous group.

According to IUCN, the environment in which the spiders live is severely affected by deforestation, a major impact on creeping spiders in old forests.

Although it is determined that there are at least 40 species of photovoltaic green spiders , scientists still do not know why they evolved into this color.

The environment where this spider lives is seriously affected by deforestation.

In 2015, the team at Akron University, Ohio, USA, hypothesized that the special color of spiders is likely not due to sex selection."Many different sources and mechanisms create electro-optical green color. There is convincing evidence that this green has a very important visual signal function," BBC quoted Bor-Kai Hsiung, the leader of the research team. assist.

Researchers believe that colors can help spiders hide from predators at night, but Hsiung emphasized: "We don't know for sure."
