Charybdis hellerii is a potential threat to native crab populations and benthic communities and its introduction should be avoided by adhering to ballast water management guidelines. view this species on IUCN Red List Species Description Charybdis hellerii is a small crab measuring from about 5-8 cm wide. It is dark green with a light purple on the upper inner surface of palm and dark purple on dorsal surfaces of distal 4 segments of walking and swimming legs. The carapace has pale green to whitish areas on frontal, hepatic, and epibranchial regions. It is most easily identifiable by the spine on the posterior of the carpus on the fifth leg which bears its chela, or claws giving it one of its common names: spiny hands. Its dorsal carapace is naked and its anterolateral margin has 6 prominent black-tipped teeth.

BRACHYURAN COMMUNITY IN UBATUBA BAY, NORTHERN COAST OF SAO PAULO STATE, BRAZIL FERNANDO LUIS MEDINA MANTELATTO1 AND ADILSON FRANSOZO2 1 Departamento de Biologia, FFCLRP Universidade de Sao Paulo, Cep. 14040-901 Ribeirao Preto, SP, Brasil Departamento de Zoologia Institute de Biociincias, UNESP Botucatu, Cep. 18618-000 Botucatu, SP, Brasil ABSTRACT A brachyuran crab assemblage from eight transects at a non-consolidated sublittoral site in Ubatuba Bay was studied on a monthly basis from September 1995 to August 1996. Data about number of individuals of 50 species found and other information such as distribution of the dominant crabs are reported. The family Majidae was represented by 13 species, followed by Xanthidae (13), Portunidae (10), Leucosiidae (5), Calappidae (2), Dromiidae (2), Parthenopidae (2), Goneplacidae (1), Pinnotheridae (1), and Ocy- podidae (1). The brachyuran taxocoenosis was dominated by Callinectes ornatus (60.4%), Callinectes danae (18.8%), and Hepatus pudibundus (7.7%), representing together 86.9% of the total number of collected brachyurans. The Shannon-Weaver diversity index ranged from 1.10 to 2.06 between transects, and from 1.34 to 2.22 between months, depending more on equitability than on richness.

  • Marine Bioinvasions in the Brazilian Coast: Brief Report on History of Events, Vectors, Ecology, Impacts and Management of Non-Indigenous Species
    Chapter 27 Marine Bioinvasions in the Brazilian Coast: Brief Report on History of Events, Vectors, Ecology, Impacts and Management of Non-indigenous Species Carlos Eduardo Leite Ferreira, Andrea de Oliveira Ribeiro Junqueira, Maria Célia Villac, and Rubens Mendes Lopes 27.1 Introduction The Brazilian coast extends for about 8000 km from Cape Orange (4°N) to Chui (34°S) (Fig. 27.1). This long coastline comprises a variety of ecosystems under the influence of oligotrophic waters transported by two western boundary currents, the Brazil and North Brazil currents (Stramma and England 1999), together with con- tinental influences related to a wide spectrum of river inputs, the largest of which being the massive Amazon River plume in the north and the combination of the La Plata and Patos Lagoon outflows in the south (Castro Filho and Miranda 1998). Seasonal or intermittent intrusions of cold and nutrient-rich oceanic waters carried underneath the Brazil and North Brazil currents (the so-called South Atlantic Central Water) is another important physical forcing on regional shelf ecosystems of Brazil, particularly on the Southern Brazilian Bight and more southern areas (Lopes et al. 2006). Regionally important coastal ecosystems are (1) sandy beaches, occurring from north to south, with the largest ones in southernmost areas of the state of Rio Grande do Sul; (2) mangrove forests, which occur from the northern tip of the country to the state of Santa Catarina in the south, (3) coral reefs, ranging from Maranhão to Bahia including the largest coral reef system of the South Atlantic, the Abrolhos Reefs (Leão et al.

SOCIETY OF WASHINGTON 108(4):643-648. 1995 Charybdis hellerii (Milne Edwards, 1867), a nonindigenous portunid crab (Crustacea: Decapoda: Brachyura) discovered in the Indian River lagoon system of Florida Rafael Lemaitre Department of Invertebrate Zoology, National Museum of Natural History, Smithsonian Institution, Washington, D.C. 20560, U.S.A. Abstract.—The portunid crab Charybdis hellerii (Milne Edwards, 1867), a species of Indo-Pacilic origin, is reported from the Indian River lagoon system of Florida. Although this species was reported in 1987-1988 from Cuba, Co- lombia, and Venezuela, this is the fii^t subsequent record in the western At- lantic, and the first in the continental United States. The specimens found in the Indian River include adults of both sexes (one female ovigerous), and juveniles, indicating that the population is reproducing and that this nonindig- enous species has become established in the region. This species must now be considered present in the tropical western Atlantic at least across the entire Caribbean region. Recognition characters of C. hellerii are provided, as well as a summary of what is known about its distribution, biology, and probable method of arrival. Comments on other marine decapods introduced in eastern North America are included.

    Obvious Invaders and Overlooked Infauna: Unexpected Constituents of the Decapod Crustacean Fauna at Twin Cays, Belize Darryl L. Felder, Peter C. Dworschak, Rafael Robles, Heather D. Bracken, Amanda M. Windsor, Jennifer M. Felder, and Rafael Lemaitre ABSTRACT. Decapod crustaceans in the vicinity of Carrie Bow Cay and Twin Cays, Belize, have been under study for more than 25 years. Large collections have been as- sembled, and new species have been discovered. The effort has included photographic documentation of coloration, yielding characters of value in identifi cation of problematic tropical taxa. Measurements of diversity have been markedly enhanced by extraction corer (yabby pump) sampling in shallow subtidal sediments, especially at Twin Cays. This technique revealed species, genera, and families of thalassinidean decapods not pre- viously known from the region. Studies continue on the ecological roles of these burrow- ers, dominant bioturbators in seagrass beds where they produce conspicuous mounds of sediment and constitute a major infaunal biomass at Twin Cays. By contrast, famil- iar large reptant decapods typically dominate shallow rocky substrates. Within the past four years, however, the nonindigenous portunid crab Charybdis hellerii has extensively invaded large portions of hard substrates at Twin Cays. In 2007, it was found to domi- nate cavities under coral heads in survey areas along the northeastern and southwestern shorelines, possibly displacing populations of large Mithrax, Menippe, Callinectes, and Panulirus previously found there in abundance. INTRODUCTION Fieldwork centered on Carrie Bow Cay and surrounding habitats, including Darryl L. Felder, Rafael Robles, Heather D. a variety of settings at Twin Cays. The effort continues work by the fi rst author Bracken, Amanda M.

The present record is based on several specimens collected at two localities in Ceará, Pedra Rachada beach near the town of Paracuru, and Meireles beach in Fortaleza. Athanas dimorphus is very common at the second site, suggesting that a population of this species is now established in northwestern Brazil. An updated list of marine and freshwater decapods accidentally or voluntarily introduced to Brazil is provided. Key words: Decapoda, Caridea, Alpheidae, new record, invasive species Introduction Pacific and the western Atlantic. In April 2011, a single specimen The shrimp genusAthanas Leach, 1814 belonging to the genus Athanas was collected is distributed in tropical, subtropical and from an intertidal pool at Pedra Rachada warm-temperate areas of the Indo-West Pacific beach, near the town of Paracuru, Ceará, and eastern Atlantic, mostly in shallow waters Brazil (Fig.

  • Aquatic Invasive Species
    Aquatic Invasive Species A Guide to Non-native Species in Coastal Georgia Alan Power, Anna Rahn, Thomas Bliss The University of Georgia Marine Extension Service 1 Coastal Georgia Habitats Georgia has a relatively short coastline, but contains a significant propor- tion of the remaining salt marsh habitat on the East Coast. The salt marsh is characterized by expansive grasslands, mudflats, and meandering tidal creeks fringed with dense oyster reefs. These provide important ecological services including pollution, flooding, and erosion control and are essential habitat for a myriad of commercially important fish and shellfish species. There are thirteen major barrier islands which contain approximately 90 miles of sandy beaches that are being continually shaped and changed by ocean currents, waves, and wind. Sand dunes, beaches, sandbars, and shoals comprise a vital natural resource system that protects the coastline from the damaging effects of floods, winds, tides, and erosion. Important Native Species Salt Marsh Plants: smooth cordgrass, glasswort, saltwort, salt grass, needle rush, sea oxeye daisy, marsh elder, and eastern red cedar Salt Marsh Animals: oyster, fiddler crab, mud snail, periwinkle, blue crab, shrimp, clam, mussel, whelk, killifish, wading birds, waterfowl, and shore birds Beach Plants: sea oats, pennywort, yucca, camphorweed, and dune primrose Beach Animals: dolphin, sea turtle, ghost crab, sand dollar, horseshoe crab, sponge, bass, trout, stingray, shark, catfish, gulls, hermit crab, jellyfish, sea whip, olive shell, and moon snail 2 Aquatic Invasive Species Impacts An aquatic invasive species (AIS) is any freshwater or The southeastern United States has the largest number of marine species that is not native to an ecosystem and aquatic invasive species in the nation and the rate of new whose introduction does or is likely to cause economic or introductions is increasing.

In the current work, five different crab species were collected from the northern part DNA barcoding; of the Egyptian Red Sea. They were morphologically identified through description of colors, den- Morophological identifica- tations of the carapace and shapes of chelipeds and pereiopods. They were also genetically charac- tion; terized by the partial sequencing of the barcode region in the mitochondrial cytochrome oxidase Cytochrome oxidase subunit subunit I (COI) gene, which is known to be hypervariable among different crab species. Morpho- I (COI) gene logical and genetic characterization identified the crab species as: Charybdis (Charybdis) hellerii (A. Milne-Edwards, 1867), Charybdis (Charybdis) natator (Herbst, 1794), Portunus (Portunus) pelagicus (Linnaeus, 1758), Liocarcinus corrugatus (Pennant, 1777), and Atergatis roseus (Ru¨ ppell, 1830).
