The total weight of all the spiders on Earth is 25 million tons. 90 percent of their victims are insects, but large tropical spiders are able to catch small vertebrates — frogs, lizards, snakes, birds and bats. Eight-legged arthropods kill a large number of insects in forests and meadows, thereby controlling their numbers in the wild ecosystems.

According to the Food and agriculture organization of the UN, people across the planet eat 400 million tons of meat and fish annually, which is comparable to the biomass ingested by the spiders, according to Lenta.ru.

Spiders (agapee) are one of the most widespread and diverse groups of predators. This group of arthropods includes over 40 thousand views.
