Article
The genus Dendrodoris is ascribed to the family Dendrodorididae, whose members are characterized lacking spicules in the dorsum as well as a radula, one of the most important taxonomic traits to distinguish and define nudibranch species. The absence of this taxonomic character makes difficult to delineate species based on morphologic traits, and co...

The genus Thuridilla Bergh, 1872 comprises mostly tropical sap‐sucking sea slugs species with flamboyantly coloured forms. However, the potential for cryptic or pseudocryptic species masked by convergent or polymorphic colour patterns has not been tested using molecular characters. In this study, we sampled 20 of the 23 recognized worldwide species...

Despite the importance of dispersal behavior in the eco-evolutionary responses of species to global environmental change, its role in the invasion dynamic of stowaway invaders has been poorly studied, especially in low-mobile species (i.e. with direct development). Here we use peracarid crustaceans as a target group to understand the role that loca...
Article
The similarities and variations in nudibranch species of the “Chromodoris quadricolor group” (Heterobranchia, Nudibranchia) have historically created identification prob- lems among both nudibranch enthusiasts and experts. In this study, we combine molecular genetic analyses using one nuclear gene (histone h3) and two mitochon- drial genes (cytochr...
