imagine growing tools out of this stuff instead of forging or casting, that'd be neat.

Ah, but how many one pound bags of concrete could it hold??

Why bags of anything? This is a poor way of communicating weight. Just say "a modern passenger car".

more importantly: how many kilos of feathers versus how many kilos of steel can it hold?

It’s a real condition. For me it’s jet liners of various makes. I had to rewrite the quote as “0.005 Boeing 777’s” to be able to comprehend just how strong those snails teeth are.

Understandable, with how many there are to pick from, and the wiggle room in the longest ones -

because as a reader, bags of sugar are more engaging to me than bags of concrete.

Is that cooked or raw spaghetti?

Why complicate matters with pasta at all when spider silk is, at least metaphorically and rhetorically, at hand?

I noticed that too. I feel like this might be a new way of laundering AI written text, just provide the quote verbatim as if the they believe it was actually written by the author.

I wanted to see some pictures, this paper has good ones:

If you put your finger in front of a garden slug it may try to eat it, it's a very odd sand-paper sensation but I never knew why.

Garden snails around seattle will absolutely bite you (teeny tiny bite) and draw blood if you let them crawl around on your skin.

"try"? If it's harder than your skin it means it did, not tried.

Analogous to the keratinous denticles in a cat tongue, just much smaller in scale.

What an odd example. A mid-sized car would have been much clearer.

Snails had a good run being ignored by everyone but the French and now we're smearing their slime on our faces and trying to turn their teeth into armor.

Makes you wonder how and why they evolved such strong teeth since crayons are pretty soft (and not even naturally-occurring).

Which is the less intelligent? Strong works when dumb.

I know people like to talk about “how smart” the butterfly or whatever is for “adapting itself” to whatever environment, and it is cute, but there is a practical engineering choice between delicate design and brute force.
