Strombus vittatus
Encyclopedia
Doxander vittatus, common name : the Vitate Conch, is a species
of medium-sized sea snail
, a marine
gastropod mollusk in the family
Strombidae
, the true conchs.
There are three subspecies :
along Fiji
and in the South China Sea
.
(a tree of descent) that attempts to show the phylogenetic relationships of 34 species within the family Strombidae. The authors analysed 31 species that used to belong to the genus Strombus
including Strombus vittatus, 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 vittatus and Strombus canarium
are closely related and appear to share a common ancestor.
Species
In biology, a species is one of the basic units of biological classification and a taxonomic rank. A species is often defined as a group of organisms capable of interbreeding and producing fertile offspring. While in many cases this definition is adequate, more precise or differing measures are...

Family (biology)
In biological classification, family is* a taxonomic rank. Other well-known ranks are life, domain, kingdom, phylum, class, order, genus, and species, with family fitting between order and genus. As for the other well-known ranks, there is the option of an immediately lower rank, indicated by the...

Phylogeny
In 2006, Latiolais et al. proposed a cladogramCladogram
A cladogram is a diagram used in cladistics which shows ancestral relations between organisms, to represent the evolutionary tree of life. Although traditionally such cladograms were generated largely on the basis of morphological characters, DNA and RNA sequencing data and computational...
