“…For example, smooth valve edges occur in members of the Arca imbricata Bruguie`re, 1789 complex (including A. avellana Lamarck, 1819 from the Indo-West Pacific, A. imbricata from the western Atlantic and A. mutabilis Sowerby, 1833 from the eastern Pacific); some species of Barbatia s. l. [e.g. B. cancellaria (Lamarck, 1819) from the Caribbean, B. foliata (Forsska˚l, 1775) from the western Pacific, the modioliform central Indo-West Pacific B. obliquata (Gray, 1837) and B. virescens (Reeve, 1844)] and the genera Arcoptera (Early Pleistocene of Florida), Asperarca, Bathyarca, Bentarca and Trisidos (see also Reinhart, 1935;Kilburn, 1983;Kamenev, 2007a, b;Francisco, Barros & Lima, 2012). The same condition occurs in some noetiids including Arcopsis, Didimacar and Estellacar (Vongpanich & Matsukuma, 2004), limopsids including Nipponolimopsis and several groups within Limopsis (Oliver, 1981;Amano & Lutaenko, 2004;Sasaki & Haga, 2007); and the cucullaeid Cucullaea (Morton, 1981).…”

Molluscan marginalia: hidden morphological diversity at the bivalve shell edge

Molluscan shells exhibit a high and largely neglected diversity of serrations and crenulations at the growing margin. A survey of living and Cenozoic fossil bivalves indicates that serrations, in which the external ribs or interspaces between ribs extend radially beyond the general contour of the valve margin, may be symmetrical or asymmetrical. Projections whose adumbonal edge more nearly parallels the shell edge than the abumbonal edge occur on the posterior valve margins of many limids, cardiids and donacids, as well as in the arcid Anadara and a few concentrically ridged tellinids. In many cardiids, posterior serrations form as extensions of ribs, whereas ventral and anterior projections are extensions of rib interspaces. Asymmetrical serrations are almost always found on shell edges that are polished, indicating that the mantle extends slightly over the valve margin to the outside. I tentatively suggest that asymmetrical serrations enable the valves to close around siphons or other mantle extensions without injuring these soft tissues, so that the bivalve can maintain sensory contact with the environment even while the shell is shut. A preliminary comparison with brachiopods indicates that the diversity of conditions at the shell edge is much higher in bivalves. Together with the largely warm-water and marine distribution of marginal modifications in bivalves, these comparisons reflect the higher metabolic potentials of bivalves relative to brachiopods, and show that the shell edge is a rich source of evidence about function and mode of life in fossils.

“…Arcidae Lamarck, 1809 is a large and diverse family of marine bivalves distributed worldwide in warm and shallow tropical seas. It is represented by 12 living genera and between 200 and 250 species inhabiting a wide array of benthic environments from the lower intertidal to sublittoral zones (Francisco et al , 2012). The family Arcidae is represented in Galician waters by about five species with only one of them, A. polii , belonging to the genus Anadara (Rolán et al , 1994).…”

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 to confirm its identification. This new record reaffirms the presence of A. kagoshimensis, previously reported as Anadara inaequivalvis, along the Atlantic European coast extending the known distribution range in Spanish waters to the south.

“…Bastante comum em mares tropicais, para o Brasil registram-se 21 espécies para a família, classificadas nos gêneros Acar, Arca, Anadara, Aspearca, Barbatia, Bathyarca, Bentharca e Paranadara (Diaz & Puyana, 1994;Simone & Chichvarkhin, 2004;Passos & Birman, 2009;Rios, 1994Rios, , 2009Simone, 2009;Francisco et al, 2012). Distribuídas por toda a costa brasileira, algumas espécies não ocorrem na região Sul do país (Rios, 2009).…”

“…Oliver & Holmes (2006) afirmam, após estudo sistemático da ordem Arcoidae, a necessidade de mais dados morfológicos para resolver as relações da família Arcidade, principalmente quando comparadas a família Noetiidae. Estudos conquiológicos, principalmente quando se tratam de novas espécies, são difíceis devido à falta de consenso na definição de gêneros e a disposição destes dentro da família Arcidae (Oliver & Holmes, 2006;Francisco et al, 2012).…”

O objetivo do estudo é complementar a literatura sobre a família Arcidae, onde foi utilizado o enfoque morfométrico – que permite a comparação de padrões morfológicos a partir de caracteres multivariados. Os espécimes disponíveis para o estudo são provenientes da Coleção Malacológica “Prof. Henry Ramos Matthews” (CMPHRM), da Universidade Federal do Ceará, onde foram utilizadas a valvas direitas. Após identificação foram tomadas oito medidas: comprimento da charneira, comprimento da concha, posição do umbo (prodisoconcha), altura do umbo (prodisoconcha), altura da porção anterior da concha, altura média da concha, altura da porção posterior da concha e comprimento da porção posterior da concha. As medidas são previamente conhecidas como ‘marcos anatômicos’ da família. Os dados foram analisados em pacotes estatísticos e as médias dos tamanhos das conchas apresentaram-se coerentes as medidas apresentadas na literatura. Algumas medidas foram significantes na diferenciação das espécies estudadas. Os espécimes analisados, que possuem proximidade geográfica, apresentam similaridade morfológica.
