Diminovula

Diminovula is a genus of small, predatory sea snails, marine gastropod mollusks in the family Ovulidae, the cowries. They are commonly known as false cowries because of their resemblance to the true cowries (genus Cypraea). The genus was first established by the American malacologist, John P.E. Morrison, in 1955, but its validity and status were questioned for decades. More recent studies using molecular phylogeny have confirmed its status as a valid taxon within the family Ovulidae. Currently, the genus Diminovula encompasses about 15 species, most of which inhabit the Indo-Pacific region. CharacteristicsDiminovula species are distinguished from other ovulids by a number of morphological characteristics, including:Small size: Typically ranging from 5 to 15 millimeters in length.Smooth, polished shell: The shell is generally ovate or pyriform (pear-shaped) with a smooth, glossy surface.Lack of denticles: Unlike most other ovulids, Diminovula species lack denticles on the outer lip of their shell.Coloration: The shells display a variety of colors and patterns, often with bright, contrasting shades. Some species have a distinctive “bullseye” pattern with a central circular spot surrounded by concentric rings. EnvironmentDiminovula species are found in a range of shallow-water marine habitats, primarily in tropical and subtropical regions. They are often associated with coral reefs and seagrass beds, where they feed on other small invertebrates, such as hydroids and bryozoans.
