They found carnivorous polychaete worms and heat-tolerant limpets that seem to have slipped between the cracks in the seafloor to colonise the cavities underneath.
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.
I continued three days feeding on oysters and limpets, to save my own provisions; and I fortunately found a brook of excellent water, which gave me great relief.
