Conopleura latiaxisa is a species of sea snail, a marine gastropod mollusk in the family Drilliidae. [1]
Its shell is relatively small for the genus, around 11 mm in length, slender shaped, thick, solid and semi-fusiform, early four whorls elate, acuminate spire, well swollen periphery[ clarification needed ]. The body whorl is half of the shell length, with a protoconch of about 1.5 whorls. The teleoconch consists of around 5 to 6 convex whorls with a tall spire. Narrow axial ribs reach from suture to suture.
The species is only known from the type locality, which is situated between 180 and 250 m deep, near Mactan Island, Cebu, the Philippines.
The species lives on sandy mud with small gravel.
The word "latiaxisa" refers to the particular characteristics of trigonal spines, which reminds one of the genus Latiaxis in the subfamily Coralliophiliinae in the Muricidae.
The gastropod shell is part of the body of a gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or the shell is reduced such that the body cannot be retracted within (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the aperture, which provides further protection. The study of mollusc shells is known as conchology. The biological study of gastropods, and other molluscs in general, is malacology. Shell morphology terms vary by species group. An excellent source for terminology of the gastropod shell is "How to Know the Eastern Land Snails" by John B. Burch now freely available at the Hathi Trust Digital Library.
