Where to see them

Did you know…

  • Its radular teeth, reinforced with goethite fibres, are the strongest biological material in tension ever measured, ahead of spider silk.

    From Common Limpet

  • It practises homing: it wears a scar into the rock that matches the rim of its shell exactly, and always returns to the same spot after feeding.

    From Common Limpet

  • By grazing it stops algae from colonising the rock, which shapes the whole intertidal community.

    From Common Limpet

  • The hole at the apex is an outlet for water and waste: a one-way circulation system that keeps the gills from being fouled.

    From Common Keyhole Limpet

  • The mantle can fold back over the edge of the shell and partly cover it.

    From Common Keyhole Limpet

  • It is not a true limpet. Keyhole limpets have a hole at the apex of the shell through which they expel respiratory water and waste, so that intake and outflow are separate.
