Ithycythara muricoides is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae. [1]
This species has become a synonym of Ithycythara lanceolata (C. B. Adams, 1850) [2]
The length of the shell attains 10 mm.
(Original description) The pure white shell is fusiform and slender.. The longitudinal sculpture shows six narrow subacute prominent ribs on each whorl, which are sinuated posteriorly on the right side, and which are continuous along the spire like a species in the genus Murex .The spiral sculpture consists of very numerous microscopic spiral striae in the intercostal spaces. The apex is acute. The outlines of the spire are nearly rectilinear. The shell contains six slightly convex whorls, with a lightly impressed suture. The body whorl is gradually attenuated below into a wide siphonal canal. [3]
This marine species occurs off Jamaica, Honduras and Barbados.
Acteonidae, common name the "barrel bubble snails", is a family of small sea snails, marine gastropod mollusks of the informal group Lower Heterobranchia.
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.
