From Mud to Meat: Comparative Metabarcoding Reveals Two Different Evolutionary Paths to Carnivory in a Group of Meiofaunal Annelids

open access: yesMolecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT Evolutionary transitions to carnivory represent profound shifts in feeding mode that are often accompanied by widespread changes in organismal function, behaviour and ecology. Such transitions have evolved numerous times among animals, and predator–prey interactions have been major drivers of animal evolution.

A new Felimare (Mollusca: Heterobranchia: Nudibranchia) of the Atlantic blue chromodorid chromatic group from Cape Verde

open access: yesScientia Marina, 2017
A new species of the chromodorid genus Felimare (Gastropoda: Heterobranchia) of the Atlantic blue chromatic group is described using material from Cape Verde (eastern Atlantic). Felimare aurantimaculata n. sp.

Diversity and behavior of sea slugs (Heterobranchia) in the rocky tide pools of Conero Riviera (western Adriatic Sea)

open access: yesThe European Zoological Journal, 2022
Rocky tide pools are transition environments whose communities are affected by sudden temperature, salinity and nutrient fluctuations. Furthermore, these environments are exposed to multiple stressors and can be easily altered by human trampling.

Origin and Biogeography of the Colourful Sap‐Sucking Sea Slugs Genus Thuridilla Bergh, 1872 (Mollusca, Gastropoda, Heterobranchia)

open access: yesJournal of Biogeography, Volume 52, Issue 10, October 2025.
ABSTRACT Aim Thuridilla Bergh, 1872, is a lineage of herbivorous sea slugs externally distinguished by bright colours and distinctive patterns of lines and spots. Recent work revealed an exceptionally rapid, cryptic radiation of 13 species in the Indo‐Pacific, raising questions about mechanisms of speciation in this group.

Diel activity correlates with colour pattern morphology of heterobranch sea slugs

open access: yesJournal of Animal Ecology, Volume 94, Issue 6, Page 1165-1179, June 2025.
The authors show that daytime activity fundamentally shapes the appearance of prey animals to potential predators and that colour pattern phenotypes likely associated with visual signalling are predominantly found in diurnal species of sea slugs. This study showcases novel methodology combining comparative phylogenetic analyses, animal vision modelling,

The Heterobranchia -a new concept of the phylogeny of the higher Gastropoda

open access: yesJournal of Zoological Systematics and Evolutionary Research, 2009
Abstract In an attempt to reconstruct the phylogeny of the higher gastropods, the essential characters are first critically examined to determine occurrence and systematic value. From here the evolutionary pathway is cladistically analysed from a common prosobranch ancestor up to the basal pulmonates.

Mitochondrial Genomes of Three Melampus Species (Ellobiidae; Gastropoda)

open access: yesEcology and Evolution, Volume 15, Issue 4, April 2025.
The mitochondrial genomes of three gastropod species from the family Ellobiidae—Melampus bidentatus, Melampus jaumei, and Melampus gundlachi—were assembled and annotated and found to have a gene order that diverges from the conserved gene order that is recovered in most genera within Ellobiidae and—more generally—within Euthyneura.
