“…Records of it cover the coast from New York (CASTAGNA and CHANLEY, 1973) to the Gulf of Mexico (MARELLI and GRAY, 1983), from the North and Baltic Seas (GOLLASCH and NEHRING, 2006) to France (VERWEEN et al 2005) and include the Mediterranean coast of Spain (ESCOT et al, 2003) and Ukraine (Therriault et al, 2004). It was introduced in 2004 in the estuarine area of Recife and the most plausible hypothesis for their occurrence and regional dispersion suggests accidental introduction through ballast water and/or vessel hull fouling (SOUZA et al, 2005, FARRAPEIRA, 2006. Farrapeira et al (2007) then found it on 12 vessels in the harbor area of the city, including the vessel later examined in Natal for this study.…”

“…The bioecological behavior of Mytilopsis leucophaeta, for example, is considered eurybiotic, mainly brackish and highly euryhaline; it normally occurs in waters that range from fresh to those whose salinity exceeds 20, while its temperature tolerance varies from 5 to 30ºC for adults and from 10 to 30ºC for larvae (VERWEEN et al, 2007). In Recife's mesohaline Pina Basin it is submitted to salinities that range from 10 to 30 (low and high tide, respectively) (SOUZA et al, 2005).…”

A B S T R A C TThis study aimed to identify the incrusting and sedentary animals associated with the hull of a tugboat active in the ports of Pernambuco and later loaned to the port of Natal, Rio Grande do Norte. Thus, areas with dense biofouling were scraped and the species then classified in terms of their bioinvasive status for the Brazilian coast. Six were native to Brazil, two were cryptogenic and 16 nonindigenous; nine of the latter were classified as established (Musculus lateralis, Sphenia fragilis, Balanus trigonus, Biflustra savartii, Botrylloides nigrum, Didemnum psammatodes, Herdmania pallida, Microscosmus exasperatus, and Symplegma rubra) and three as invasive (Mytilopsis leucophaeta, Amphibalanus reticulatus, and Striatobalanus amaryllis). The presence of M. leucophaeata, Amphibalanus eburneus and A. reticulatus on the boat's hull propitiated their introduction onto the Natal coast. The occurrence of a great number of tunicate species in Natal reflected the port area's benthic diversity and facilitated the inclusion of two bivalves -Musculus lateralis and Sphenia fragilis -found in their siphons and in the interstices between colonies or individuals, respectively. The results show the role of biofouling on boat hulls in the introduction of nonindigenous species and that the port of Recife acts as a source of some species. R E S U M OEste trabalho objetivou identificar os animais incrustantes e sedentários associados ao casco de um rebocador que atuava nos Portos de Pernambuco e foi cedido para o Porto de Natal, Rio Grande do Norte. Áreas com densa bioincrustação foram raspadas e as espécies foram posteriormente classificadas em relação ao status de bioinvasão no litoral brasileiro. Dentre as espécies identificadas, seis eram nativas do Brasil, duas criptogênicas e 16 exóticas. Destas, oito foram classificadas como estabelecidas (Musculus lateralis, Sphenia fragilis, Balanus trigonus, Biflustra savartii, Botrylloides nigrum, Didemnum psammatodes, Herdmania pallida, Microscosmus exasperatus, Symplegma rubra) e três como invasoras (Mytilopsis leucophaeta, Amphibalanus reticulatus e Striatobalanus amaryllis). A presença de M. leucophaeata, Amphibalanus eburneus e A. reticulatus no casco da embarcação, propiciou sua introdução na costa de Natal. A ocorrência de grande número de espécies de tunicados em Natal refletiu a biodiversidade bêntica da área portuária e facilitou a inclusão de dois bivalves, Musculus lateralis e Sphenia fragilis, encontrados em seus sifões e nos interstícios entre colônias ou indivíduos, respectivamente. Os dados obtidos indicam que a incrustação em cascos de embarcações tem um papel preponderante na introdução de espécies exóticas, e que o Porto do Recife atuou como fonte de algumas destas espécies.

“…The infested specimens of the scallop Nodipecten nodosus, studied herein, were cultivated in a marine farm in north São Paulo coast (Ubatuba), where M. aristatus is considered a problem (Álvares, personal communication). Beyond I. bicolor, other two marine species have been considered as invasive in Brazilian waters, the mytilid Perna perna (Linné, 1758) (Souza et al 2004) and the dreissenid Mytilopsis leucophaeta (Conrad, 1831) (Souza et al, 2005), both also possibly coming from the Caribbean.…”

The bivalve Myoforceps aristatus (Dillwyn, 1817), also known as Lithophaga aristata, have been recently collected in the coasts of Rio de Janeiro and São Paulo, Brazil; a species that bores shells of other mollusks. This occurrence has been interpreted as an invasion of this species, originally from the Caribbean. The distinguishing character of the species is the posterior extensions of the shell crossing with each other. Because specimens with this character have also been collected in the Pacific Ocean, they all have been considered a single species. However, it is possible that more than one species may be involved in such worldwide distribution. With the objective of providing full information based on Atlantic specimens, a complete anatomical description is provided, which can be used in comparative studies with specimens from other oceans. Additional distinctive features of M. aristatus are the complexity of the incurrent siphon, the kidney opening widely into the supra-branchial chamber (instead of via a nephropore), and the multilobed auricle.KEYWORDS: Myoforceps aristatus, biological invasion, boring bivalve, Brazil, anatomy, systematics.Samples belonging to Myoforceps aristatus have been collected in the southeastern coast of Brazil in the last two years, far outside of the normal geographic range of the species. The samples were found in shells of larger size, including cultivated scallops (Pectinidae), and attracted attention as an invading bivalve causing possible damage to native species, because the datemussels perforate living shells, causing deformation of the host and even its death.Only one species of the closely related genus Lithophaga Röding, 1798, is commonly found on the (Dillwyn, 1817), previously known as Lithophaga aristata, is a small bivalve that bores into calcareous hard substrata, mainly shells of other mollusks. In the western Atlantic, the species is known from North Carolina to Florida, the Gulf of Mexico and the northern Caribbean Sea. The species is easily identified by pointed tips at the posterior ends of the valves, which cross like fingers (Abbott, 1974) and give the common name of the species as "scissor datemussel". INTRODUCTION Myoforceps aristatus SIMONE, L.R.L. & GONÇALVES, E.P.: MYOPHORCEPS ARISTATUS, AN INVASIVE BIVALVE IN BRAZILS.E. Brazilian coast. Lithophaga bisulcata (Orbigny, 1842) is of larger size, normally inhabits soft rocks and corals, and it is not usually found boring into shells.This paper reports the first occurrence of Myoforceps aristatus, another invasive species on the Brazilian coast, and provides new data on its morphology and anatomy. The geographic distribution of the M. aristatus includes the Pacific (e.g., Turner & Boss, 1962;Abbott, 1974), as samples of Myoforceps with crossing posterior ends of the shell have also been collected in that ocean. This paper provides anatomical information that can be used in future comparative studies with samples from other oceans. MATERIAL AND METHODSThe available specimens were preserved in 70% E...

“…Particularmente C. rhizophorae, la especie con mayor biomasa, es común y abundante en otros sistemas costeros del Caribe (Márquez & Jimé-nez, 2002;Quiceno Cuartas & Palacio Baena, 2008;Quirós & Arias, 2013;Acosta Balbas et al, 2014). Sin embargo, M. leucophaeata, la especie más abundante, no ha sido registrada en ninguno de los anteriores trabajos, pues se distribuye en el Golfo de México hasta Massachusetts (Marelli & Gray, 1983), aunque es invasora de algunas costas europeas (Laine, Mattila, & Lehikoinen, 2006) y brasileñas (Souza, Rocha, & Lima, 2005). Por otra parte, F. miamiensis, una especie pionera y de rápido crecimiento, colonizó rápidamente los horizontes más altos en las raíces al aumentar el nivel de inundación en febrero, pero tras la apertura de la boca estuarina los individuos establecidos murieron por desecación.…”

Variación espacio-temporal de la comunidad de macroinvertebrados epibiontes en las raíces del mangle rojo Rhizophora mangle (Rhizophoraceae) en la laguna costera de La Mancha, Veracruz, México Abstract: Spatial-temporal variation of the macroinvertebrate epibiont community on red mangrove prop roots Rhizophora mangle (Rhizophoraceae) at La Mancha coastal lagoon, Veracruz, Mexico. La Mancha lagoon is connected to the Gulf of Mexico through an estuarine ephemeral inlet, a sand bar, which opens during the rainy season and closes during the late fall and the winter storm season. As the lagoon fills up with the permanent stream flow into its Southern part, the water level increases and the sand bar opens up, releasing huge volumes of water into the ocean and leaving the previously flooded intertidal zone exposed to drying. In this study, we described the spatial and temporal variations of structure and composition of the community living on the surface of red mangrove prop roots, related to the hydrodynamic of the estuarine inlet. Four red mangrove prop roots were collected every three months, over an annual period, at ten sampling stations. Water temperature, salinity, dissolved oxygen, water depth and transparency were also measured at each sampling event. To describe the identity, abundance, biomass, and specific richness of epibiont coverage on the prop roots, measurements were taken at 10cm intervals (herein called "horizons"). A total of 59 632 specimens and a total biomass of 172g/cm 2 were registered, and a maximum of eleven horizons presented at least one species of epibionts. Two species of polychaetes, 12 of mollusks and 14 of crustaceans were identified, with Mytilopsis leucophaeata as the most abundant, Ficopomatus miamiensis as the most common and Crassostrea rhizophorae with the highest contribution in biomass. Sampling effort was assessed using species accumulation curves, resulting that the efficiency was, in general, greater than 90% of the richness predicted by asymptotic models. The hydrodynamics of the estuarine inlet had a great influence on the environmental conditions of the lagoon and on the spatial and temporal variation of the epibiont community: (a) when the inlet is open, there is a North-South gradient in environmental parameters (b) when the inlet is closed and the water level increases, the epibionts especially the pioneer species F. miamiensis, occupied the highest horizons of prop roots, and (c) the abundance, biomass and richness of epibionts increased towards the deeper and less saline Southern part of the lagoon, as well as on permanently submerged horizons, and during the seasonal closure of the inlet. Variations in depth are determined by the hydrodynamic behavior of the estuarine inlet, suggesting that these factors are major biodiversity drivers of the epibiont community at La Mancha. Rev. Biol. Trop. 62 (4): 1309-1330. Epub 2014 December 01.
