Spiders’ diet can really make you astonished

The word “spider” always reminds me of Robert Bruce’s story, the story of the great King of Scotland who once became deserter and hid himself in the cave. While laying hopelessly on his straw bed, Robert instantly watched a timid poor spider who was hanging by a thread from one wooden beam and was trying to reach another beam. The spider failed several times in its attempt but did not lose its heart; it remained consistent in its attempt and at last succeeded in its attempt.

The again and again attempt of the spider taught Bruce a great lesson and provided him new ray sunshine.

But from now, spider will not only flash me on lessons of consistency and hard-work but it will always recall me about its diet to make me astonished.

It is very hard to believe on, what the study tells, that spiders eat up to 800 million tonnes of meat annually which is double than the amount of meat human eat. They do not only eat juicy insects but also lizards, snakes, frogs, fish and many other mammals. (Think, if their love for prey would take them to have human flesh in dinner.)

In contrast to spiders, humans annually consumes just 440 million tons of meat, the biggest mammals, Whales, eat 300 to 500 million tons of seafood where as, seabirds feed 77 million tons of meat.

It is said that this appetite of spiders contribute a lot to maintain ecological balance as they eat up to 720 million insects yearly.

“Our calculations let us quantify for the first time on a global scale that spiders are major natural enemies of insects,” Martin Nyffeler, from the University of Basel in Switzerland, said. He added, “In concert with other insectivorous animals such as ants and birds, they help to reduce the population densities of insects significantly. Spiders thus make an essential contribution to maintaining the ecological balance of nature.”

Martin Nyffeler has been researching over spiders for 40 years and determined these estimates by using data from 65 previous studies.

Only spiders don’t scare others, but there are also many creatures found which make it frightened. Spiders are the essential part of about 5,000 bird species, set aside other predators.
