I was wondering how they could tell the age of the spider so accurately. It seems this spider has actually been tracked for decades.

- riffic 8y agoScientists cut it open and count the spider rings.
- stinos 8y agoSeeing this is HN you might get downvoted for jokes.. Still, when reading the article and before getting to the part where they say the spider's entire life was monitored, I also envisioned a person in a labcoat cutting a leg and counting rings. Or performing some carbon-test like procedure.
- Kirth 8y agoThat's a bit misleading. Spiders may grow more than one ring during a good year and less than one during a bad year. But overall, it should average out.
