The Mitochondrial Genomes of the Nudibranch Mollusks, Melibe leonina and Tritonia diomedea, and Their Impact on Gastropod Phylogeny. [PDF]

open access: yesPLoS ONE, 2015
The phylogenetic relationships among certain groups of gastropods have remained unresolved in recent studies, especially in the diverse subclass Opisthobranchia, where nudibranchs have been poorly represented.

Notes on Opisthobranchia [PDF]

open access: diamondBoletim do Instituto Oceanográfico, 1956
Acteon punctostriatus (C. B. Ad.), ainda nao indicado do Brasil, parece ser vastamente distribuido, do Cabo Cod ate a regiao de Bahia Blanca, Argentina. As plaquinhas mandibulares e os dentes da radula assemelham-se as estruturas correspondentes de A. tornatilis (L.). Haminoea elegans (Gray) tem olhos do tipo de Helix e Gastropteron.

Diversity and distribution of the Gastropoda Opisthobranchia from the Atlantic Ocean: A global biogeographic approach

open access: diamondScientia Marina, 2009
A zoogeographic study of the Opisthobranchia (Mollusca, Gastropoda) from the Atlantic Ocean was carried out. Data on Opisthobranch occurrence were collated from literature records and databases.

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

open access: yesBMC Evolutionary Biology, 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.

Observations on the ontogenetic and intraspecific changes in the radula of Polycera aurantiomarginata García and Bobo, 1984 (Gastropoda Opisthobranchia ) from Southern Spain

open access: diamondScientia Marina, 2006
Polycera aurantiomarginata García and Bobo 1984 has a stable population in the intertidal area of El Portil beach (Huelva, SW Spain). This fact allowed specimens of different sizes to be collected from March 2001 to December 2003.

Phylogenetic relationships within the Phyllidiidae (Opisthobranchia, Nudibranchia). [PDF]

open access: yesZookeys, 2016
The Phyllidiidae (Gastropoda, Heterobranchia, Nudibranchia) is a family of colourful nudibranchs found on Indo-Pacific coral reefs. Despite the abundant and widespread occurrence of many species, their phylogenetic relationships are not well known.

From sea to land and beyond – New insights into the evolution of euthyneuran Gastropoda (Mollusca) [PDF]

open access: yesBMC Evolutionary Biology, 2008
Background The Euthyneura are considered to be the most successful and diverse group of Gastropoda. Phylogenetically, they are riven with controversy.
