Liracraea otakauica is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae.[1]
There is one subspecies: Liracraea odhneri benthicola Dell, 1956
Liracraea otakauica is a small marine gastropod mollusk characterized by a slender, elongate-conic shell. The shell reaches a length of approximately 7.8 mm and a diameter of about 2.7 mm.[2]
The sculpture of the shell includes numerous fine axial ribs intersected by spiral cords, producing a reticulate or cancellate surface pattern. The whorls are convex, with well-marked sutures. The aperture is narrow and elongate, with a distinct siphonal canal, and the outer lip is sharp and simple.
The protoconch is smooth, suggesting planktotrophic larval development. The shell is generally off-white or pale cream in color, which is typical for deep-sea mangeliid species. Internal anatomy and soft-body morphology remain poorly documented, as is common for many deep-water conoidean gastropods.
