The broad girdle is fringed with 18-20 dense tufts of colourless bristles, four surrounding the head valve and two at each valve intersection. There are short spines and randomly distributed curves spines that also cover the remainder of the girdle. In the posterior region of the mantle groove there are 10-15 pairs of gills.
'Coat-of-mail' shells get they're name from the armoured appearance of the valves like links in chain mail. These eight valves allow Acanthochitona crinita to bend and tightly cling onto uneven rock surfaces. When dislodged, they roll up like woodlice.
