Canarium scalariforme is a species of sea snail, a marine gastropod mollusk in the family Strombidae, the true conchs. Description Distribution This species occurs in the Indian Ocean off the Mascarene Basin. Phylogeny In 2006, Latiolais and colleagues proposed a cladogram (a tree of descent) that attempts to show the phylogenetic relationships of 34 species within the family Strombidae. The authors analysed 31 species in the genus Strombus including Canarium haemastoma (referred to as Strombus haemastoma in their analysis), and three species in the allied genus Lambis. The cladogram was based on DNA sequences of both nuclear histone H3 and mitochondrial cytochrome-c oxidase I (COI) protein-coding gene regions. In this proposed phylogeny, Strombus labiatus (= Canarium labiatum) and Strombus microurceus are closely related and appear to share a common ancestor. References Duclos, P.L. (1833). Strombe.
