The annual diet of all spiders in the world has been calculated by scientists

Specialists from the Universities of Basel and Lund calculated the amount of food eaten by all the Earth's spiders during the year. The scientific work was published by The Science of Nature. 

There are 45 thousand species of these arthropods on our planet. The density of the spider population is 1000 individuals per square meter and their total weight is 25 million tons. As a result of the study, it was found that this huge community eats 800 million tons of extraction annually. 

For comparison scientists have named the quantity of meat and fish which people consume for the same period. The figure is half as small and equals 400 million tons. 

When collecting statistics, the nutritional characteristics of different species of spiders were taken into account: inhabitants of forests and meadows are more gluttonous than their desert congeners.

Thousands of teeth in front of whale sharks were discovered by scientists

 Japanese biologists have found that the eyeballs of fish are reliably protected by a huge number of dermal dental structures. The study has published PLoS ONE.   The eyes of these giant marine creatures have no eyelids and are located in a vulnerable spot on the sides of the head. Specialists have found that each of the animal's visual organs is dotted with three thousand tiny teeth, whose strong enamel prevents the appearance of a variety of damages.   It is noted that the small hard organs also cover other parts of the body of a large harmless creature. This helps reduce friction in the water, helping to develop high speed. More news:  Animal Good News
