Description. Shell up to c. 100 mm high, most specimens smaller, to c. 60 mm; rather thin to more solid, moderately to strongly inflated, almost equally convex; juveniles elongate, some acline; adults more nearly semi-circular and weakly prosocline; equivalve, slightly inequilateral, anterior auricles much larger and longer than posterior, umbonal angle c. 95° in juveniles, increasing to c. 110° in adults; colour polychromatic, many specimens reddish brown with a range of maculations.

Both valves sculptured with 24–30 evenly spaced, prominent, squamous radial plicae, flanked by subdivided squamous secondary and narrow spinous tertiary riblets in interplical spaces. Herringbone-like (complex of comm- and antimarginal) microsculpture in interstices. Auricles delicately radially sculptured as on disc, anterior auricle of right valve more coarsely sculptured with c. 5 prominent and 4 fine secondary riblets. Byssal notch deep, byssal fasciole moderately broad. Functional ctenolium well-developed, with 4–7 teeth. Internal rib carinae weakly developed on most specimens, short, present around ventral margin of thick shells. Resilial and dorsal teeth moderately prominent.

Dimensions. Illustrated specimen: TAS, D’Entrecasteaux Channel, 18 m (AM C.097543): rv: H 69.6, L 66.6 mm; lv: H 69.8, L 67.6 mm; D 25.5 mm.

Habitat. Mimachlamys asperrima   is the most abundant and widespread scallop in southern Australia, living in the littoral zone to the upper bathyal zone in eastern and southeastern Australia from southern Queensland to Carnarvon, Western Australia, byssally attached to jetty piles, Pinna   shells and rubble, always covered in sponges ( Hymedesmia species   , det. R. W. M. van Soest, ZMA). The significance of epizoic sponges on scallop shells for the avoidance of starfish predators was described by Pitcher & Butler (1987); the sponge helps prevent recognition of the scallop by the predator. Consequently, apparently to help sponge adhesion, many species of chlamydoid scallops secrete more spinous sculpture on their plicae and costae when overgrown with sponge. In New Zealand and southern Australia, this includes most Talochlamys   and Mimachlamys species   and Zygochlamys delicatula   (Dijkstra & Marshall, 2008: 56, 68, figs 53A, E). Adults of Mimachlamys asperrima   become detached and live amongst weed and rubble in the littoral zone on soft sediment (sand/mud). In Tasmania, Mimachlamys asperrima   grows to a much larger size than elsewhere and is found in similar surroundings to Equichlamys bifrons   , in sand, mud and shell rubble (pers. comm. H. Morrison, 2002). Studies of its abundance and distribution in Tasmania have been carried out by (among others) Zacharin (1994) and Mendo et al. (2014).

Distribution. Southern Queensland (c. 26°S) southwards all around southern Australia to Western Australia (c. 24°S). Present specimens alive in the intertidal zone to 110 m (generally in 5–45 m); specimens from the Great Australian Bight live in exceptional depths (146–220 m).

Remarks. Mimachlamys asperrima   is variable in size and thickness. The largest and thinnest specimens are found around Tasmania. Smaller and more solid shells occur along the mainland coast. It is also variable in convexity (from weakly to strongly inflated), radial sculpture (primary plicae and secondary costae with variable tertiary sculpture), and colour (polychromatic or uniformly brownish coloured).

This “doughboy scallop” is a locally common and occasionally commercially harvested species in Tasmanian waters.
