Stramonita
Predatory marine snails of the rock snail family Muricidae.
Stramonita is a genus of predatory marine snails, specifically gastropod molluscs belonging to the rock snail family Muricidae and the subfamily Rapaninae. These snails have a raised spire, and their whorls may be either smooth or knobby. The aperture is of moderate size and extends forward, while the columella is curved and plain toward the front.
The genus includes the following species: Stramonita alderi, Stramonita biserialis, Stramonita brasiliensis, Stramonita buchecki, Stramonita canaliculata, Stramonita dayunensis, Stramonita delessertiana, Stramonita floridana, Stramonita haemastoma, and Stramonita rustica.
Several former species are now considered synonyms. Stramonita armigera is accepted as Mancinella armigera. Stramonita bicarinata is accepted as Stramonita rustica. Stramonita blainvillei is a synonym of Stramonita delessertiana. Stramonita chocolata is accepted as Thaisella chocolata. Stramonita hederacea is a synonym of Nassa serta. Stramonita muricina is accepted as Semiricinula muricina.

Lore & Background
The genus Stramonita comprises marine gastropod molluscs that are predators on tropical rocky seashores. Their shells feature an elevated spire, and the whorls may be simple or nodulous. The aperture is moderate and extends forward, while the columella is rounded and simple at the front.
Species within Stramonita include Stramonita alderi, Stramonita biserialis, Stramonita brasiliensis, Stramonita buchecki, Stramonita canaliculata, Stramonita dayunensis, Stramonita delessertiana, Stramonita floridana, Stramonita haemastoma, and Stramonita rustica. Several former species have been brought into synonymy, such as Stramonita armigera accepted as Mancinella armigera, and Stramonita bicarinata accepted as Stramonita rustica.
The genus has been studied in the context of global phylogeny and classification of the Rapaninae, which are dominant molluscan predators on tropical rocky seashores. Research has also addressed the geographic scale of speciation in a marine snail with high dispersal potential.
Reader's Guide
Stramonita holds significance as a genus of predatory sea snails within the Muricidae family, specifically in the subfamily Rapaninae. These snails are dominant molluscan predators on tropical rocky seashores, playing a key ecological role in their habitats. The genus has been the subject of phylogenetic studies that have informed the classification of the Rapaninae, with molecular work clarifying relationships among species. The geographic scale of speciation in Stramonita has been investigated, highlighting the high dispersal potential of these marine gastropods. The species list includes both extant taxa and those brought into synonymy, reflecting ongoing taxonomic refinement. References to European marine species checklists and guides to identification place Stramonita within broader biodiversity inventories. The legacy of the genus is tied to its representation of predatory adaptation in rocky intertidal zones and its contribution to understanding evolutionary processes in marine snails with wide-ranging larval dispersal.
