Eastern Mediterranean bathyal depths with low levels of dioxygen. The animal lives burrowed in gas-saturated mud on the Anaximander volcanic system.
« The shell of L. kazani resembles that of L. borealis, but the umbos are more prominent and directed more inwards and forwards; the lunule is distinctly broader and better delimited; the hinge plate is slightly larger and less curved than in L. borealis. » – Salas & Woodside: “Lucinoma kazani n. sp. (Mollusca, Bivalvia): evidence of a living community associated with a cold seep in the Eastern Mediterranean Sea”, Deep-Sea Research part I vol. 49, 2002, p.1000.

Above and below: single valves collected at 1909m deep, off Demre, west of Antalya (meaning that the spot was probably located on Kula Mud Volcano). Sizes about 32mm.
« The hinge is also different, L. kazani having a rather prominent, knob-like anterior lateral in each valve, whereas these are obsolete in L. borealis. » – Ibid. This anterior is more markedly bifid in the left valve of borealis than in kazani (top view, anterior at right). Also, the posterior lateral of kazani (bottom view, posterior at right) is less markedly bifid than in borealis.
« Moreover, the angle between the ventral extension of the anterior adductor and the pallial line is greater (ca. 25°) than in L. borealis (ca. 15°). » – Ibid. On the pictured specimens, this angle θ is of about 25° to 30°. Left valve on top.
