Abstract This article reports the first record of the Nudibranch Polycera hedgpethi in the Lagoon of Venice (Italy), as well as its established presence in the Mediterranean Sea after its first record in 1986 in lake Fusaro (Naples). In less than 50 years P. hedgpethi has spread throughout the world's temperate and subtropical waters, preferring protected coastal environments and other semi-enclosed coastal water bodies such as ports, harbours and lagoons. Shipping is the most likely vector… 

Azores , July 2013 The genus Polycera Cuvier , 1817 ( Nudibranchia : Polyceridae ) in the eastern Pacific Ocean , with redescription of Polycera alabe Collier & Farmer , 1964 and description of a new species

Specimens similar to P. alabe in the external coloration, but with several external and internal differences such as the type of salivary glands and number of outermost teeth, are described as a new species, P. anae n.

New Mediterranean Biodiversity Records (July 2018)

New records are given for 15 species (4 native and 9 alien and 2 cryptogenic), belonging to 6 Phyla, from 10 Mediterranean countries, showing that this species has extended its range in a very short time.

Alien molluscan species established along the Italian shores: an update, with discussions on some Mediterranean “alien species” categories

COI sequences obtained indicate that a comprehensive survey of additional European localities is needed to elucidate the dispersal pathways of Haminoea japonica, and ten taxa are no longer considered as alien species, or their records from Italy are refuted.

The potentially invasive opisthobranch Polycera hedgpethi Er. Marcus, 1964 (Gastropoda Nudibranchia), introduced in a Me - diterranean coastal lagoon

The non-native opisthobranch Polycera hedgpethi Er. Marcus, 1964 is reported from the coastal lagoon of Capo Peloro (Central Mediterranean Sea) with notes on its habitat typology and feeding

Current status and trends of biological invasions in the Lagoon of Venice, a hotspot of marine NIS introductions in the Mediterranean Sea

The Lagoon of Venice is a known hotspot of NIS introductions within the Mediterranean Sea, hosting all the most important vectors of introduction of marine NIS—shipping, recreational boating, shellfish culture and live seafood trade.

Mobile epifauna of the invasive bryozoan Tricellaria inopinata: is there a potential invasional meltdown?

Whether the specific morphology and annual cycle of T. inopinata is favouring the establishment of other introduced species like those found here, and hindering other native species, is discussed, and future lines of research to address this phenomenon are proposed.

Integrative taxonomy reveals a cryptic species of the nudibranch genus Polycera (Polyceridae) in European waters

Abstract This work aimed to test whether the colour variability featured by the European nudibranch Polycera quadrilineata is consistent with the concept of a single polychromatic species or may hide

The alien nudibranch Polycera hedgpethi Er. Marcus, 1964, has been found in the Gulf of Cadiz (El Portil, Huelva). The present record in the Gulf of Cadiz could be considered an opportunity to

Distribution of the introduced amphipod, Caprella mutica Schurin, 1935 (Amphipoda: Caprellida: Caprellidae) on the west coast of Scotland and a review of its global distribution

The local scale distribution of C. mutica is potentially limited by the availability of suitable transportation vectors during the dispersal phase rather than by physical environmental factors following release, which suggests that the species has not yet been found in natural habitats.

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

The richness of opisthobranchs increases from polar to tropical regions along Atlantic shores, and there is a latitudinal and longitudinal separation of the biogeographical areas.

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

Correlations between specimen length and radula length, number of rows and mean length of outer lateral teeth were significant, and feeding strategies could be related to the different morphology of the radula established by the Cluster analysis.

The goal of this supplement is to bring current the biological, biogeographical, morphological and taxonomic information concerning those species found along this coastline by incorporating both published material and confirmed observations of field workers and opisthobranch enthusiasts.

American opisthobranch mollusks

A large collection of gastropods belonging to the Museum of the Institute of Marine Sciences of the University of Miami, it contains two species of prosobranchs belonging to families traditionally studied together with opisthobranchs, and the majority of the animals came from Florida and the West Indies, although some were collected on the Pacific side of the Canal Zone.

A new species of dorid nudibranch of Polycera is described for Bahia de Banderas, along the Pacific coast of Mexico, and its coloration is distinct from all other known species ofPolycera.

Factors promoting marine invasions: A chemoecological approach

A chemoecological approach is proposed here to define biotic conditions that promote biological invasions in terms of enemy escape and resource opportunities, and to propose aposematism in the former and dietary autonomy in producing defensive metabolites in the latter case as predisposing factors to the migration.
