Evolution is driven by natural selection operating on the genes present in a given species. However, it is unclear if the different parts of a gene (coding and non-coding) are under the same types of selection as each other. Determining the similarity . . .

Juliidae E.A. Smith, 1885 is a family of Sacoglossan bivalve gastropods mistakenly placed in Bivalvia when initially discovered. These are the only known gastropods with bivalve shells, making them a morphologically unique group. A recent morphologica . . .

The genus Cyerce Bergh 1871 is a group of heterobranch sea slugs in the family Caliphyllidae, characterized as having bifid rhinophores, enrolled oral tentacles, multiple leaf-like cerata, and a transverse groove splitting the foot sole of the animal . . .

Micromelo undatus (Bruguière, 1792), represents the only species in the genus Micromelo (Family Aplustridae). This species of "bubble snail" is generally found in warm, tropical and subtropical waters across the globe. Recent work on other globally di . . .

Phylogenetic classification at the species level in the Boraginaceae is notoriously difficult when relying solely on morphological data. Studies are currently in progress to generate a well-supported phylogenetic tree of this family using molecular da . . .
