Marine Snails of the Genus Phorcus: Biology and Ecology of Sentinel Species for Human Impacts on the Rocky Shores
DOI: 10.5772/intechopen.71614 Provisional chapter Chapter 7 Marine Snails of the Genus Phorcus: Biology and MarineEcology Snails of Sentinel of the Species Genus Phorcusfor Human: Biology Impacts and on the EcologyRocky Shores of Sentinel Species for Human Impacts on the Rocky Shores Ricardo Sousa, João Delgado, José A. González, Mafalda Freitas and Paulo Henriques Ricardo Sousa, João Delgado, José A. González, MafaldaAdditional information Freitas and is available Paulo at Henriques the end of the chapter Additional information is available at the end of the chapter http://dx.doi.org/10.5772/intechopen.71614 Abstract In this review article, the authors explore a broad spectrum of subjects associated to marine snails of the genus Phorcus Risso, 1826, namely, distribution, habitat, behaviour and life history traits, and the consequences of anthropological impacts, such as fisheries, pollution, and climate changes, on these species. This work focuses on discussing the ecological importance of these sentinel species and their interactions in the rocky shores as well as the anthropogenic impacts to which they are subjected. One of the main anthro- pogenic stresses that affect Phorcus species is fisheries. Topshell harvesting is recognized as occurring since prehistoric times and has evolved through time from a subsistence to commercial exploitation level. However, there is a gap of information concerning these species that hinders stock assessment and management required for sustainable exploi- tation. Additionally, these keystone species are useful tools in assessing coastal habitat quality, due to their eco-biological features. Contamination of these species with heavy metals carries serious risk for animal and human health due to their potential of biomag- nification in the food chain. -
Descriptions of Marine Gastroporla from Ceylon, &C
157 DeSC1'iptions of 'Ynctl'ine Gast'f'oporZa from Oeylon, g-c, j by MESSRS. G. AJjfD H. NBVILL, [Reoeived and 1'ead 3rd February, 1869.] This paper is a continuation of the one we hacl the honour or placing before the Society at the Augnst meeting of last year (18G8). These new species, as likewise those previously described, were, with one exception, collected in the SOllthern. Province of Ceylon, mostly near Balapiti; the Rapcma, one of 111'3 had previously also fonnel at J.1a Rlh1ll10n. (Bombon). We have also seen several of the small species ox TROdHIDlE from Bombay and Aralmu, probably all of them are to be met with along our coasts, though the small and interesting little species, we l1ave here llalllecl E'IbClteltw Seychella1'ltm, we have never met with anywhere in these seas, except at the Islam1 of Mah6, one of the Seychelle group.

Aceptado el 24-V-2012 ABSTRACT A recent molecular study has shown that the well-known intertidal Cape Verde topshell, previ- ously identified as Osilinus punctulatus, O. tamsi or O. atratus, is a distinct undescribed species (DONALD,PRESTON,WILLIAMS,REID,WINNER,ALVAREZ,BUGE,HAWKINS,TEMPLADO &SPENCER, 2012). Therefore we describe it here as new for science and compare it to the closest species.

Anatomy of Zetela Alphonsi Vilvens, 2002 Casts Doubt on Its Original Placement Based on Conchological Characters
SPIXIANA 40 2 161-170 München, Dezember 2017 ISSN 0341-8391 Anatomy of Zetela alphonsi Vilvens, 2002 casts doubt on its original placement based on conchological characters (Mollusca, Solariellidae) Enrico Schwabe, Martin Heß, Lauren Sumner-Rooney & Javier Sellanes Schwabe, E., Heß, M., Sumner-Rooney, L. H. & Sellanes, J. 2017. Anatomy of Zetela alphonsi Vilvens, 2002 casts doubt on its original placement based on con- chological characters (Mollusca, Solariellidae). Spixiana 40 (2): 161-170. Zetela is a genus of marine gastropods belonging to the family Solariellidae (Vetigastropoda, Trochoidea). The species Zetela alphonsi Vilvens, 2002 was origi- nally described using classical conchological characters from samples obtained from deep water off Chiloé, Chile, but no other features were recorded in the original description. In the present paper, taxonomically relevant characters such as the operculum, radula, and soft part anatomy are illustrated and described for the first time from a specimen of Zetela alphonsi from a new locality, a methane seep area off the coast of central Chile. We find that many features differ substantially from other members of the genus, including several which deviate from characters that are diagnostic for Zetela. Zetela alphonsi also lacks retinal screening pigment, giving the appearance of eyelessness from gross examination. Although pigmenta- tion loss has been reported in other deep sea genera, this feature has not been re- ported in any other members of Zetela. We reconstructed a tomographic model of the eye and eyestalk, and demonstrate that a vestigial eye is still present but exter- nally invisible due to the loss of pigmentation. Based on these new morphological characters, particularly observations of the radula, we suggest that the current placement of this species in the genus Zetela should be reconsidered.
