The observations carried out during the spring of 2014 on different Atlantic salmon (Salmo salar Linnaeus, 1758) sea farms around the island of Frøya (Sor-Trøndelag), Norway, served to lay the foundations for a totally natural and environmentally friendly method for removal salmon parasitic copepods known as sea lice. The method is based on two kno...
Resume No presente traballo inclúense os resultados do estudo de material recolectado en 68 localidades situadas ao longo de toda a costa galega (NW España), en profundidades que abranguen dende o intermareal ata os 249 m. Inclúense novos datos relevantes para un total de 54 especies. Amplíase o límite batimétrico inferior para 33 especies na costa...
Although the bryozoological fauna of Galicia (NW Spain) is probably the best known of the whole Iberian Peninsula, and perhaps one of the better known in Europe, new studies continue to provide new knowledge. A new species, Schizotheca galaica sp. nov., is described. Eleven species are newly recorded in Galicia: Aetea longicollis, Parellisina curvi...
Samplings carried out in the last years by the "Grupo de Estudo do Medio Mariño" (GEMM) in Ría de Arousa, have resulted in the discovery of four species never recorded before in the Iberian Peninsula waters. New data on the feeding habits of Atagema gibba Pruvot-Fol, 1951, Onchidoris bilamellata (Linné, 1767) and Armina neapolitana (Delle Chiaje, 1...
Schilderia achatidea achatidea (Gray in Sowerby I, 1837) is one of the four indigenous taxa of the family Cypraeidae in European waters along with Luria lurida, Zonaria pyrum and Naria spurca.
In this article we give some notes concerning the northernmost range of this cowry in Europe (and, most likely, in the world). We focused our interest on the...
La nueva guía de los moluscos marinos de Galicia es una obra en la que se tratan un total de 630 especies de moluscos diferentes. Considerando que las conocidas en nuestras aguas rondan las 900, se puede decir que aparecen en esta guía prácticamente todas las que pueden encontrarse entre el nivel intermareal y los 200 metros de profundidad. Cuenta...
Two unusual crustacean decapods are reported for the first time from the coasts of Galicia (NW Spain). A specimen of caramote prawn Penaeus kerathurus (Penaeidae) was caught in the Ría de Arousa in 2014 and a specimen of blue crab Callinectes sapidus (Portunidae) was caught in the Ría de Vigo in 2015, the first one being a native species whereas th...
Samplings carried out in the last years by the “Grupo de Estudo do Medio Mariño” (GEMM) in Ría de Arousa, have resulted in the finding of two species never found before in the Iberian Peninsula waters: Atagema gibba Pruvot-Fol, 1951 and Onchidoris bilamellata (Linné, 1767). New data on the feeding habits of both species are given, as well as some d...
Ten unusual decapod crustacean species are reported for the coasts of Galicia (NW Spain), eight of them recorded for the first time in this area. Three species: Pilumnopeus africanus, Charybdis hellerii and Pachygrapsus gracilis, are non-indigenous species. The reports of Panopeus africanus and Inachus aguiarii represent the northernmost localities...
The occurrence of the alien species
Anadara kagoshimensis
is reported for the first time in the Ría de Arousa (Galicia, NW Spain) during 2013. Living specimens of this species have been recognized by morphological analysis. The cytochrome c oxidase subunit I gene has been partially sequenced and Maximum likelihood and Bayesian analyses carried out...
New species of the gastropod family Ovulidae FLEMING, 1828 are described from the Gibraltar Strait of Morocco and from Japan. The first new species from Morocco is assigned to the genus Simnia RISSO, 1826. Type species of the genus is Simnia nicaeensis RISSO, 1826. Almost ten shells of Simnia jacintoi, spec. nov. are consistently distinguished from...
The caprellid amphipod, Caprella mutica, is a well-known invasive species, originating in the Sea of Japan, which has been rapidly expanding along the coasts of North America, Europe and Oceania for the last forty years. Caprella mutica is frequently associated with man-made structures, especially those dedicated to aquaculture activities, where it...
Five non‐native marine species were found in 2013 during a series of underwater dive inspections on fouling of tuna boats coming from the port of Abidjan (Ivory Coast). These vessels perform the same routes steadily, carrying frozen tuna to the Galician shores. Several specimens of the Asian bryozoa Biflustra perambulata and the West African mangro...
The caprellid amphipod, Caprella mutica(Schurin,1935),is a well-known invasive species, originating in the Sea of Japan, which has been rapidly expanding along the coasts of North America, Europe and Oceania for the last forty years. Caprella mutica is frequently associated with man-made structures, especially those dedicated to aquaculture activit...
Sampling works carried out at Ría de Arousa (Galicia, NW Spain) have
resulted in the discovery of numerous specimens of Cumanotus cuenoti, Pruvot-Fol,
1948, which is the first record for the Iberian Peninsula and the southernmost one
known for this species. In the case of Cumanotus beaumonti (Eliot, 1906), appearances
confirm the existence of stabl...
Eubranchus linensis is a species described in 1990 by García-Gómez and Cervera, and mor-phologically different from any of the varieties described in Eubran-chus farrani, with which it shares only certain similarities. The range originally described for this species is located in the south of the Iberian Peninsula. The samplings carried out in the...
Three Ovulidae species not previously recorded from Ria de Arousa (NW Spain) are presented. Out of these three species, two represent the first record from European Atlantic. furthermore, it demonstrates the validity of Simnia nicaeensis Risso, 1826 as a distinct species and the maintenance of the genus Simnia for S. aperta (Sowerby II, 1848).
The presence of the non-indigenous species, the black-pygmy mussel Xenostrobus securis, is reported here for the first time in an intense shellfish farming area off Galicia (NW Spain). Very high concentrations
of this mytilid bivalve have colonized estuarine waters located at the inner part of the Ria de Vigo. The invasive role of
X. securis is dis...
The Galician (NW Spain) population of Calliostoma conulum (Linnaeus, 1758) is analyzed, and it is confirmed that the species is rather common in this area. The geographical distribution of the species is figured. Some differences with the Mediterranean populations are shown and the radula is figured for the first time.
As result of collecting made in a bay where molluscs are cultured for comercial propose, is found the transport of foreign species and the implatation of one of them in this palce as the first Atlantic one, noticing th erisks that a future implantation of another species could be for the ecology of this area.
Questions

In DNA analysis carried out with 2 batches of 5 specimens each, belonging to the Mytilidae family and which in the existing bibliography are reported as belonging to the same species, a difference of 2% has been obtained. Is this difference enough to ensure that they are different species?
Always attached to red and white gorgonies. From South Portugal to Northern Spain.
These are the best photos that I could have taken. Scutum and tergum.

Recopilación de datos de localización de colonias de bivalvos perforadores en las costas atlánticas y cantábricas de la península ibérica con el objetivo de extender su protección legal fuera del Mediterráneo, donde si están protegidos, principalmente Pholas dactylus (Linneo, 1758).
