Callochiton dentatus, the broad chiton, is a medium to large-sized polyplacophoran mollusc in the family Callochitonidae,[1] found on the coast of southern Africa.

This is a very flat and broad chiton with valves that are dark brown to orange, shiny and finely granulated.

The wide girdle is densely covered with very small, elongate scales that produce a velvet-like texture.

It is uncommon and can usually be found as solitary individuals under rocks near the low tide mark.

[2] The original description by Lorenz Spengler recorded it at the Cape of Good Hope.
