Snails' teeth beats spider silk as nature's strongest material (2015)
Snail (limpet) teeth are highlighted as one of nature’s strongest known materials, with research suggesting their tensile strength can rival or exceed that of spider silk. Commenters critique how popular articles muddle concepts like tensile vs. compressive strength and rely on awkward analogies (bags of sugar, spaghetti strands, football fields) instead of clear units. The thread branches into biomaterials applications (from armor to tools), curiosity about how these teeth work biologically, and the broader challenge of communicating scientific results accurately to the public.
Measurement analogies and unit jokes
- Many comments mock the article’s use of “3,300 one‑pound bags of sugar” and “a strand of spaghetti” as analogies.
- Alternative “units” proposed: modern passenger cars, football fields, Olympic pools, Smoots, Boeing 777s, blue whales, defensive linemen, pallets of cinder blocks, pints of beer, hogsheads/bushels, and even “cheeks per tongue.”
- Some argue bags of sugar are relatable (common in kitchens); others have never seen them and find cars or lifts of people clearer.
- There is confusion between U.S. and U.K. pounds, metric vs imperial, and whether such analogies help at all.
Material properties and article issues
- Several note the article (and even a source article) mixes up tensile strength, compressive strength, hardness, and toughness.
- Teeth are intuitively thought to be strong in compression, yet the limpet/snail teeth discussed work by scraping rock, so tensile strength might indeed be relevant.
- The spaghetti comparison is widely seen as odd and unclear, especially without specifying raw vs cooked pasta.
Biology, images, and behavior
- Readers seek pictures of snail/limpet teeth and share links to research and image-rich papers.
- Some describe the sensation of snails or slugs “biting” fingers as sandpaper-like, with debate over whether this actually breaks skin or just feels rough.
- Garden snails in some regions reportedly can give tiny bites that draw blood.
Health risks and ethics
- A tangent covers parasitic infection from snails/slugs (rat lungworm), including a case where eating a slug as a dare led to years of severe disability and death.
- This sparks brief discussion of medical assistance in dying for cases with no hope of recovery.
Applications and speculative ideas
- Commenters imagine biomimetic uses: armor, tools grown instead of forged, tunnel-boring tech, even space elevators made from snail-tooth–like materials.
- There is playful startup/YC-style satire about “democratizing” snail-tooth materials and scaling production via biotech.
