The view of a Darwin spider was discovered not so long ago. This species strikes the minds of scientists. It took about 10 years to study the life features of Darwin spiders in Madagascar.
Where was the new species of spiders discovered?
This species was first discovered on the island of Madagascar, which is located in close proximity to Africa.
This island is famous for its unique flora, fauna and exotic species of living creatures. That is why Madagascar is the most favorite study place for zoologists, botanists and other scientists. The view of the Darwin spider was discovered and described only in 2010. And it seems very strange, since these spiders weave huge networks, how could they remain invisible for so many years?
Features of the Darwin Spider WebDarwin Spider (Caerostris darwini).
First of all, the spider's web is of interest. These arthropods create networks of incredible size.
The largest recorded trap had an area of 3 square meters. But scientists insist that networks can be larger. Traps can be so large that spiders stretch them over streams and even lakes.
In their report, scientists describe a stretched thread that has reached a length of 25 meters. The circles that the Darwin spider weaves on the supporting thread reach a diameter of 1-2 meters. In terms of strength, this web is stronger than synthetic Kevlar - an innovative lightweight and very durable material that is used in aviation and in the automotive industry.
Darwin Spider DietDarwin spiders build their networks over ravines and rivers.
Darwin spiders, as noted, scatter nets over streams and small rivers. And this shows the savvy of these spiders, because it is over the water that the largest number of insects gather. Not only insects, but also inattentive birds can become victims of such strong traps.
Although Darwin’s spider webs are huge, their appetites are not that impressive. The spider cannot eat all the insects that flew into the trap. The main diet for them are moths. But here the agile local flies showed ingenuity, using the industriousness of the spiders and gladly eating prey that they do not have to catch. This is an example of a symbiosis between different types of living things.
Learning Darwin Spider LifestyleThese spiders have the largest spider web in the world.
This view was discovered by Matthias Kuntner and Inga Angarson. They drew attention to this spider in 2001 and studied it for almost 10 years. These spiders are not only distinguished by the ability to weave huge networks. Sexual dimorphism is pronounced between individuals: females are 3 times larger in size than males. Males grow to about 6 millimeters, and females grow to 18 millimeters. Since it was Darwin who became the founder of the theory of sexual dimorphism, the name of the spider came from here.Giant nets include not only insects, but also birds.
The lifestyle of this amazing spider is not fully understood. Scientists are sure that further study of this species will allow not only to learn a lot about the natural world, but also to discover new heavy-duty materials. If people learn to create material that is 10 times more durable than Kevlar, like the spider's web of Darwin, then humanity will be able to achieve a major breakthrough in the field of technology and science.Entire legends go about the durability of Darwin's spider webs.
Scientists continue to study the life of these amazing creatures, since it has not yet been found out how spiders manage to scatter nets through water bodies: how they throw the edges of their traps on different banks. To this day, research is continuing on this new species.
