Checklist of the Invertebrate Animals Reported from the Region of Port Aransas, Texas [PDF]

open access: yes, 1960
This checklist is of preliminary form with the hope that this will be a beginning for a more complete annotated list of the fauna and flora of this region. In many cases this list is quite obviously incomplete, however further work on the taxonomy of

Molecular phylogenetic analysis of Pulmonata (Mollusca: Gastropoda) on the basis of Histone-3 gene

open access: yesBeni-Suef University Journal of Basic and Applied Sciences, 2019
Background In the present study, phylogenetic relationships within Heterobranchia in particular to Pulmonata were evaluated by means of Histone-3 (H3) gene sequence information.

Mannitol oxidase and polyol dehydrogenases in the digestive gland of gastropods: Correlations with phylogeny and diet. [PDF]

open access: yesPLoS ONE, 2018
Mannitol oxidase and polyol dehydrogenases are enzymes that convert polyalcohols into sugars. Mannitol oxidase was previously investigated in terrestrial snails and slugs, being also present in a few aquatic gastropods.

Nemesignis, a Replacement Name for Nemesis Furfaro & Mariottini, 2021 (Mollusca, Gastropoda, Myrrhinidae), Preoccupied by Nemesis Risso, 1826 (Crustacea, Copepoda)

open access: yesLife, 2021
The genus Nemesis Furfaro & Mariottini, 2021, was recently introduced for an independent lineage of aeolid nudibranchs, and Dondice banyulensis Portmann & Sandmeier, 1960, established as its type species. Anyway, the presence of a senior homonym, Nemesis
