The iron snail, Chrysomallon, inhabits undersea volcanic vents. It sticks to magnets. When probed with a diamond tip indentation test, it doesn't indent.

Materials that are strong under compression aren't necessarily strong under tension, and vice-versa. I would think teeth (just) need to be really strong under compression, and spider silk really strong under tension.

I was curious about what they meant by strength, and the link at the bottom of the article says this is tensile strength. So the comparison to spider silk was actually appropriate.
I also noticed that it’s from 2015, although it was still new to me and interesting.

Strength per weight vs strength per volume are an issue as well.

Ten years ago.
Has there been any progress since then?

A startup has since been founded to commercially farm limpet teeth for use in aircraft.
First viable airplane shell is anticipated to hit the market in 2250.
