HabitatFound in sand, offshore to at least 100 m.
- Umbones are prominent and offset towards the anterior of the shell.
- Shell surface is a polished golden or reddish-brown with rays of deeper colour and of varying width radiating from the umbones.
- The shell has numerous fine, concentric lines and clear growth stages.
- Lunule is clearly defined, elongate heart shaped, slightly raised in the centre and red-brown or white.
- Three cardinal teeth are present in each valve, with a large anterior lateral tooth in the left valve fitting into a deep pit on the right valve.
- Inside of shell is white, with the adductor muscle scars and area outside the pallial line highly polished and the remainder being dull-white.
- Pallial sinus broad, with concave borders.
Additional informationCallista chione is also known as the Brown venus. Young specimens may have rows of vividly coloured spots, or three broad white bands, instead of dark streaks radiating from the umbones. Smaller specimens of Callista chione may resemble Chamelea gallina but the shell of Chamelea gallina is triangular and the lunule is deeply depressed and heart-shaped.
