*Katharina tunicata* (Wood, 1815) is commonly known as the Black Katy chiton, Black Leather chiton, Black chiton, or Leather chiton. Capable of growing up to 12 cm, the animal is generally described as being football-shaped with a black leathery girdle in which are embedded eight protective plates. The parts of the plates that are visible are sometimes (but not always) diamond-shaped in outline. The underside of the animal is dull orange or yellow.
