Description
The image displays two valves of a bivalve mollusk, identified as Tivela lessonii. One valve shows the exterior, which is smooth, somewhat trigonal-ovate, and features distinct concentric growth lines. The other valve shows the interior, revealing a whitish-blue nacreous surface, with some yellowish-green staining, likely from sediment or algae. The shell appears robust and moderately inflated.
