Sculpture smooth, glossy, without any longitudinal ribs Transverse sculpture oblique growth lines. Aperture circular Colour bone white to grey. Size: Up to 55 mm in length. Distribution: Global distribution unknown. Assumed to be endemic to Australia with a distribution from Lady Musgrave Island, central Qld, southwards to Bass Strait (Lamprell & Healy, 2008). Habitat: Dredged from 284 to 3058 m. Uncommon. Comparison: This species is similar to Laevidentalium crocinum and L. lubricatum. Lamprell & Healy (1998) provided the following points of comparison: L. largicrescens has a more expanded aperture; and there are also differences in colour (bone or grey-white in L. largicrescens, yellow or orange in L. crocinum, pure white in L. lubricatum), and curvature (L. largicrescens is less curved than the other two species).
