Fun facts

  • It owes its common name to the two reddish-orange patches around the white teeth of the aperture, which recall a bleeding tooth.
  • It is called the bleeding tooth for the orange-red blotch surrounding the two white teeth on the inner lip of the aperture, an unmistakable feature.
  • It lives in the splash zone, the highest and most exposed band of rock, where it is out of the water most of the time and only reached by spray.
  • It seals the aperture with its calcareous operculum so as not to dry out during the hours of exposure to the sun.
  • Its thick shell and strong grip are adaptations to constant wave action.
