In the Mediterranean Sea, infralittoral and circalittoral rocky bottoms (from 15 to 120 m) are characterized by a biogenic habitat, named "coralligenous", formed by the concretion of calcareous organisms, mainly algal thalli, and to a lesser extent by animal skeletons. This complex habitat is inhabited by a rich fauna that belongs to different taxonomic groups. Sponges, bryozoans, cnidarians and ascidians are the most common sessile organisms that inhabit the area, while crustacea and molluscs are the most common mobile organisms. Little information on the diversity of the molluscs that thrive in the coralligenous habitat is known, though this information is highly important for biodiversity management purposes. A database for the molluscs of the coralligenous habitat was compiled and a method implemented for the management of this information. More than 511 species of molluscs have been recorded so far from the coralligenous formations, the majority of which belong to the class Gastropoda (357 sp.) followed by Bivalvia (137 sp.), Polyplacophora (14 sp.), Cephalopoda (2 sp.) and Scaphopoda (1 sp.). Among these, the gastropod Luria lurida (Linnaeus, 1758) and Charonia lampas (Linnaeus, 1758), the endemic bivalve Pinna nobilis (Linnaeus, 1758) and the endolithic bivalve Lithophaga lithophaga (Linnaeus, 1758), are protected by international conventions.在地中海海域，水深15至120米的潮下带浅水区（infralittoral）与潮下带深水区（circalittoral）的岩质底质以生物成因生境为典型特征，该生境被称为“珊瑚藻礁（coralligenous）”，由钙质生物（主要为藻类藻体）固结形成，并辅以动物骨骼。这一复杂生境栖息着隶属于多个分类类群的丰富动物群落，其中固着生物（sessile organisms）以海绵（Sponges）、苔藓虫（Bryozoans）、刺胞动物（Cnidarians）与被囊动物（Ascidians）最为常见，移动生物（mobile organisms）则以甲壳类（Crustacea）和软体动物（Molluscs）为主。目前学界对栖息于珊瑚藻礁生境的软体动物多样性的认知仍较为有限，但此类信息对生物多样性管理工作具有极高重要性。研究人员已构建珊瑚藻礁生境软体动物数据库，并开发了配套的信息管理方法。截至目前，该生境中已记录到超过511种软体动物，其中绝大多数隶属于腹足纲（Gastropoda，357种），其次为双壳纲（Bivalvia，137种）、多板纲（Polyplacophora，14种）、头足纲（Cephalopoda，2种）以及掘足纲（Scaphopoda，1种）。其中，腹足类的Luria lurida（Linnaeus, 1758）、Charonia lampas（Linnaeus, 1758），特有双壳类Pinna nobilis（Linnaeus, 1758）以及穿石双壳类Lithophaga lithophaga（Linnaeus, 1758）受到国际公约的保护。
