Well, limpet teeth contain goethite, a crystalline form of iron, oxygen, and hydrogen.

，贝牙齿含有针铁矿， 一种铁、氧和氢结晶形式。

But as a limpet grows, goethite forms into especially compact, highly resilient, curved filaments that make it stronger than anything else in nature… that we know of.

但随着贝生长， 针铁矿会形成特别紧凑、高弹性、弯曲细丝，使其比自然界何其他东西都要坚固… … 据我们所知。
