Forever Shell: tortoise science, a swab game, and a token ticker
Credibility concern recorded. The source reference remains available for verification and correction.
An interactive story about Jonathan the giant tortoise pairs a cheek-swab science explainer with a birth-year comparison and a timing game.
- For
- Readers curious about tortoise longevity and interactive science
- Worth noticing
- The swab’s incomplete DNA was combined with a younger tortoise’s; the page says about 95% of the result is Jonathan’s genome.
Field notes
The interactive comparison accepts a birth year and places it against a timeline beginning around 1832. In the swab game, visitors watch for chewing and beak movement while the counters record samples, boops, and chomped swabs. The science section says the DNA read was incomplete, notes that results were merged with a younger tortoise’s, and cautions that a single animal cannot establish why the species lives so long. A separate patient file displays token details and market links.
