Labiostrombus epidromis
Labiostrombus epidromis, common name the swan conch, is a species of sea snail, a marine gastropod mollusc in the family Strombidae, the true conchs.
Description
The typical size of the adult shell varies between 50 and 95 mm.Distribution
This marine species occurs in the Central Indo-West Pacific,;off the Ryukyus, Japan, to Australia, and New CaledoniaPhylogeny
In 2006, Latiolais and colleagues proposed a cladogram that attempts to show the phylogenetic relationships of 34 species within the family Strombidae. The authors analysed 31 species in the genus Strombus including Labiostrombus epidromis, and three species in the allied genus Lambis. The cladogram was based on DNA sequences of both nuclear histone H3 and mitochondrial Main [subunit of cytochrome c oxidase|cytochrome-c oxidase I] protein-coding gene regions. In this proposed phylogeny, Strombus epidromis, Strombus vittatus and Strombus canarium are closely related and appear to share a common ancestor.
