Functional adaptation
The egg capsule of a sea snail resists cracks due to substituting calcium with magnesium.
"A surprising discovery is what we believe is the first record of high-magnesium calcite in molluscs. This mineral is a calcium carbonate polymorph in which Ca2+ is randomly substituted to some extent by Mg2+ in the calcite lattice; Mg substitutions over 4% (values found in O. [Odontocymbiola] magellanica capsules were 13.4– 21.1%) are considered to be high (Ries & Blaustein, 2003)...It is thought that magnesium substitution may impart a greater crack resistance to the calcite (Magdans & Gies, 2004)." (Bigatti et al. 2010:284, 286)

Volutidae
Volutidae, common name volutes, are a taxonomic family of predatory sea snails that range in size from 9 mm to over 500 mm, marine gastropod mollusks. Most of the species have no operculum.

Distribution
This family of sea snails are found mainly in tropical seas, though some species also inhabit the waters of the polar circles.
Shell description
The shell of species such as Melo amphora can grow as large as 50 cm (19.7 inches) in length.[1]
Volutes are distinguished by their distinctively marked spiral shells (to which the family name refers, voluta meaning "scroll" in Latin).
The shells have an elongated aperture in their first whorl and an inner lip characterised by a number of deep plaits. The elaborate decorations of the shells has made them a popular collectors' item, with the imperial volute (Voluta imperialis) of the Philippines being particularly prized.
Taxonomy
