Conasprella Arcuata
''Conasprella arcuata'', common name the arched cone, is a species of sea snail, a marine gastropod mollusk in the family (biology), family Conidae, the Conus, cone snails and their allies.Bouchet, P. (2015). Conasprella arcuata (Broderip & G. B. Sowerby I, 1829). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=835890 on 2015-03-19 Like all species within the genus ''Conus'', these cone snails are predatory and venomous. They are capable of "stinging" humans, therefore live ones should be handled carefully or not at all. Description The size of the shell varies between 35 mm and 60 mm. Distribution This marine species occurs in the Gulf of California, and in the Pacific Ocean from Mexico to Peru. Type (biology), Type locality near Mazatlán, Sinaloa, Mexico.Tenorio M.J., Tucker J.K. & Chaney H.W. (2012). ''The Families Conilithidae and Conidae. The Cones of the Eastern Pacific''.

Gastropod Shell
The gastropod shell is part of the body of a Gastropoda, 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 in some cases the shell is reduced such that the body cannot be retracted within it (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the Aperture (mollusc), 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. Shell layers The gastropod shell has three major layers secreted by the Mantle (mollusc), mantle. The calcareous central layer, tracum, is typically made of calcium carbonate precipitated into an organic matrix known as c ...
