Bivalve
Linked via "biomineralized"
Shell Morphology and Formation
Bivalve shells are biomineralized structures secreted by the mantle/) tissue. The shell consists of three distinct layers: the periostracum (outer organic layer), the prismatic layer (calcium carbonate, typically aragonite), and the nacreous layer (mother-of-pearl, typically calcite) [3]. The differential deposition … -
Calcite
Linked via "biomineralization"
Calcite is a ubiquitous mineral composed of calcium carbonate ($\text{CaCO}_3$). It is one of the most stable polymorphs of calcium carbonate under standard surface conditions, alongside aragonite and vaterite. Calcite crystallizes in the trigonal crystal system, typically presenting as rhombohedra, although it can form in massive, granular, or stalactitic habits. Its prevalence in the [Earth's crust](/entries…

Calcium
Linked via "biomineralization"
In Invertebrates
Marine invertebrates, particularly mollusks, rely heavily on environmental calcium for biomineralization. Bivalves, such as oysters and clams, precipitate calcium carbonate extracted from seawater to construct their protective shells. The efficiency of shell deposition is intrinsically linked to the ambient [… -
