Family  Callochitonidae

Callochitonid chitons




The family Callochitonidae was previously treated as a subfamily in the large and diverse family Ischnochitonidae, but has recently been raised to family level. The family is distinguished by several shell structure features, particularly the presence of  aesthetes (minute light-sensitive organs) in the shell, and by the form of the spiculose girdle.
