Shells of this species are characterised by a flat left valve, and a strongly convex right valve, each with 12-16 strong radial ribs. The external shell colour is extremely variable among specimens, ranging from light brown to pink and orange. Shell up to 13 cm across.
This scallop species is the one most commonly found in Victorian fish markets. They were commercially harvested throughout their natural range which resulted in a decline in population numbers, but dredging of this species is now very restricted. They are hermaphrodites, maturing at one year and typically spawning in the second year. They can live for up to 10 years if they successfully avoid predators such as sea stars and octopuses. As with other scallop species, they are capable of swimming by rapidly closing the valves of the shell which expels a jet of water and propels the animal along.
