The strength of a Kevlar fiber with the same size is only110 of spider silk. People must think that spiders must be huge, but they are not. The female spider is less than 0.02 meters long, and the male spider is smaller, with a volume of only 1/5 of that of the female spider.
National Geographic released a set of pictures showing that in 2008, a park ranger in Madagascar looked so short in front of a huge spider web across a river. As we all know, cobwebs are the strongest biomaterials in the world, and this huge cobwebs come from a new species, which is Darwin's bark spider, which makes it bigger than any cobwebs in the world.
Inji, a zoologist at the University of Puerto Rico, and his colleagues found that this Darwin bark spider web is about 25 meters wide, which is about the length of two buses. In Andasibe Mantedia National Park, "park managers know this spider web, and I think they have also shown it to tourists." Eng said.
However, Darwin's bark spiders and their huge record-breaking cobwebs were not known to scientists until Spider Magazine and Public Library of Science published the findings recorded by this research team.
The study of this species can solve the mystery of this spider silk. Almost all the research on spider silk focuses on one or two spider species, such as the golden web spider. Only by studying all kinds of spiders more widely can the mystery of species be solved. Obviously, the two typical spiders that most researchers are studying are obviously out of the range of spiders that can weave the best spider silk. So it is meaningful to study Darwin's bark spider.
