Not Politics (Orb Weaver Mix)

The scientists described their estimate of 35,176 spiders/m³ as “markedly conservative” and “representing a minimum volume” of spiders, by the way.

Question: do you measure spiders in Metric ShitTons? Or in Imperial ShitLoads?

Either way, it’s an awful lot of spiders.

It is, actually, difficult to admit just how it is that spiders affect so many of us so irrationally. And it offers no useful comfort to point to the next person and note that they’re even worse about it. Then again, four acres of orb spinners just waiting for some unfortunate organism to blunder into their trap, amounting to a population estimated somewhere above one hundred seven million spiders, and a “markedly conservative” estimate of maximum population density at 35,176 spiders/m³.

Detail of Greene, et al. (2010). Table 1 shows Architectural Elements Used to Estimate Total Amount of Volumetric Webbing in Back River Sand Filtration Facility.Come on. Admit it. You’d be just as bad about it as the next person.

The 2010 technical paper is available, for those so inclined, either through Pearson’s blog for Wired.com, or in our own archives.
