GENEVA: There are now 50,000 different known species of spiders crawling on Earth, the World Spider Catalog announced on Wednesday, and there could be another 50,000 out there.
The WSC, based at the Bern Natural History Museum in the Swiss capital, said the 50,000th recorded spider is Guriurius minuano, which belongs to the Salticidae family of jumping spiders and hunts for prey in bushes and trees in the southern Brazil, Uruguay. and surroundings of Buenos Aires.
It was described by arachnologist Kimberly S. Marta and her colleagues from Brazil and is named after the now-extinct Minuane people who lived in the area.
The first scientific description of a spider was in 1757 and although it took 265 years to reach 50,000, the discovery rate is constantly increasing and it is believed that it could take less than 100 years to discover the same number again.
“We estimate that there are still approximately 50,000 more spider species to discover,” the WSC editors said.
The spider catalog is freely available on the museum’s website.
“Spiders are the most important predators in Earth’s terrestrial habitats, and their ecological importance should not be underestimated,” the museum said.
“Consuming between 400 and 800 million tons of insects each year, they are the most important regulators of insect populations. Consequently, they are also of fundamental importance to humans.”
