From sea to land and beyond--new insights into the evolution of euthyneuran Gastropoda (Mollusca). [PDF]

BMC Evol Biol, 2008
Background The Euthyneura are considered to be the most successful and diverse group of Gastropoda. Phylogenetically, they are riven with controversy.

THE DIRECT DEVELOPMENT IN RUNCINA SETOENSIS BABA (OPISTHOBRANCHIA-CEPHALASPIDEA) [PDF]

Publications of the Seto Marine Biological Laboratory, 1959
Members of the small suborder Runcinacea have recently been reviewed and efforts have been made to group new findings (Burn, 1963; Baba, 1967; Miller & Rudman, 1968). The following structures served for the classification: gills alone (Baba, 1967), gills, radula, gizzard-plates and shell (Burn, 1963).

Molecular phylogeny of the marine snail genus Haminoea (Gastropoda, Cephalaspidea): A framework to study marine diversity and speciation [PDF]

Zoologica Scripta, Volume 53, Issue 1, Page 52-77, January 2024., 2023
Abstract Haminoea are herbivorous, coastal snails occurring in temperate and tropical waters of the Atlantic and Eastern Pacific oceans, with one species present in temperate South Africa (Indian Ocean). The genus is taxonomically difficult as several available nominal species were introduced based on shell descriptions alone, or described based on ...

New mitogenomes of Runcinidae and Facelinidae: two understudied heterobranch families (Mollusca: Gastropoda). [PDF]

Mitochondrial DNA B Resour
Here, we present the mitochondrial sequences of two sea slugs (Heterobranchia): Runcina aurata and Facelina auriculata, the latter being the type species of the family.

On the origin of Acochlidia and other enigmatic euthyneuran gastropods, with implications for the systematics of Heterobranchia. [PDF]

BMC Evol Biol, 2010
Background A robust phylogenetic hypothesis of euthyneuran gastropods, as a basis to reconstructing their evolutionary history, is still hindered by several groups of aberrant, more or less worm-like slugs with unclear phylogenetic relationships.

Opisthobranchia (Mollusca, Gastropoda) - more than just slimy slugs. Shell reduction and its implications on defence and foraging. [PDF]

Front Zool, 2005
BACKGROUND: In general shell-less slugs are considered to be slimy animals with a rather dull appearance and a pest to garden plants. But marine slugs usually are beautifully coloured animals belonging to the less-known Opisthobranchia.

GASTROPTERON POHNPEI, A NEW GASTROPTERIDAE FROM MICRONESIA (OPISTHOBRANCHIA : CEPHALASPIDEA) [PDF]

GASTROPTERON POHNPEI, A NEW GASTROPTERIDAE FROM MICRONESIA (OPISTHOBRANCHIA : CEPHALASPIDEA), 1983
While collecting in a sea grass bed on the reef flat near Nahpali, Ponape, 9 specimens of a small gastropterid species were collected from the blades of Enhalus acoroides. To the authors' knowledge this is the first member of the family Gastropteridae to be reported from Ponape.

Bizarre Morphology Obscures Real Affiliation: An Integrative Study of Enigmatic Cephalaspid Philine denticulata from Arctic Waters Reveals Its Unique Phylogenetic Position

Diversity, 2023
The biodiversity of Cephalaspidea (Gastropoda: Heterobranchia) is poorly studied, and novel findings often lead to revisions at different taxonomic levels. The family Philinidae has a distinct set of defining characters in the shell, copulatory apparatus,
