It is limpet sea snail and in particular, its teeth.

Goethite is an iron-containing nanofibre which limpet sea snails have reinforcing their teeth. It is the hardest biological product ever discovered.

These snails use their teeth to cling onto rocks as part of their feeding on lichen and algae. Naturally, their teeth are particularly strong to play this role.
