“…In a study on injuries caused by aquatic animals, cnidarians caused nearly 25% of 250 envenoming cases in Brazilian bathers in the Southeast region of Brazil [2][3][4][5][6][7] . Clinical manifestations of the envenoming generally follow a clear pattern of symptoms and signs.…”

“…The most characteristic features are linear erythematous plaques and intense pain, which are present from the moment of contact. Cnidarian species in the West Atlantic Ocean (Brazil, Caribbean, USA) are similar and rarely provoke systemic manifestations, but a minority of patients experience systemic effects that can include dyspnea, malaise, arterial hypotension, and cardiac arrhythmias 2,3,4,5,6 .…”

SUMMARYThis work attempts to establish dermatological identification patterns for Brazilian cnidarian species and a probable correlation with envenoming severity. In an observational prospective study, one hundred and twenty-eight patients from the North Coast region of São Paulo State, Brazil were seen between 2002 and 2008. About 80% of these showed only local effects (erythema, edema, and pain) with small, less than 20 cm, oval or round skin marks and impressions from small tentacles. Approximately 20% of the victims had long, more than 20 cm, linear and crossed marks with frequent systemic phenomena, such as malaise, vomiting, dyspnea, and tachycardia. The former is compatible with the common hydromedusa from Southeast and Southern Brazil (Olindias sambaquiensis). The long linear marks with intense pain and systemic phenomena are compatible with envenoming by the box jellyfish Tamoya haplonema and Chiropsalmus quadrumanus and the hydrozoan Portuguese man-of-war (Physalis physalis). There was an association between skin marks and probable accident etiology. This simple observation rule can be indicative of severity, as the Cubozoa Class (box jellyfish) and Portuguese man-of-war cause the most severe accidents. In such cases, medical attention, including intensive care, is important, as the systemic manifestations can be associated with death.

“…unguiculata (Efira, planula larvae, and adult jellyfish), and that it differs clinically according to the morphology of the skin lesion and time of year of the incident. L. unguiculata is a small Scyphozoa, approximately 1.5 cm in diameter, and is common in marine waters of the Caribbean, Gulf of Mexico and Western North Atlantic (Florida, Cuba and Bahamas), where there are numerous reports of SBE, which can reach epidemic proportions (Haddad Jr 2008, Rossetto et al 2009, Haddad Jr et al 2002.…”

Seabather's eruption is a papulo-pruritic dermatitis caused by the nematocysts of the larvae of the jellyfish Linuche unguiculata retained in the clothing fibers. Previously reported in Brazil, this work describes fourteen cases that occurred in the State of Santa Catarina, in southern Brazil. The new cases observed over a short period of time (the first half of January, 2012), at the height of the summer season, should alert health teams to possible epidemics on the coast of the state of Santa Catarina.

“…Cnidarians are characteristic of both pelagic and benthic habitats inasmuch as several of them have a complex life cycle including polyps (mostly benthic and sessile) and medusae (mostly planktonic and swimming). Besides their obvious ecological importance, cnidarians in general have significant impacts on human life, including commercial (e.g., for tourism, pharmaceutics, fisheries) (UNEP, 1991;Purcell et al, 2001), environmental (e.g., as habitat indicators) and medical interests (e.g., Freitas et al, 1995;Morandini & Marques, 1997;Marques et al, 2002;Haddad Jr. et al, 2002). Moreover, they are amongst the most basal animals, being particularly important in evolutionary studies (e.g., cf.…”

Synopsis of knowledge on Cnidaria Medusozoa from Brazil

Synopsis of knowledge on Cnidaria Medusozoa from Brazil A synopsis of knowledge concerning Medusozoa (Cnidaria) along the Brazilian coast is presented. We generated a data list with all records of medusozoans from Brazil, including information on the distribution of the species and the phase (polyp or medusa) recorded. Currently the number of species of Medusozoa recorded from Brazil is 377 (205 genera and 82 families), with 348 species of hydrozoans, 22 scyphozoans, 3 cubozoans and 1 staurozoan. Geographical and historical analyses were carried out based on the data list. The geographical analysis reveals that knowledge on biodiversity of the group is most inadequate for the North and part of the Northeastern coast. Although the Southeastern coast is the best known region in number of species and representative suprageneric taxa recorded, in general there is a lack of knowledge of the fauna in other than shallow waters, a pattern also observed for all other regions. Historically, the rapid increase of records on hydrozoans began in the 1940s and accelerated during the last decade. Investigations on coronates are all concentrated in the last decade but, in general, other groups show slow and gradual accumulation of species records. Guidelines and policies for the study of medusozoan biodiversity are suggested.

Este estudo é baseado em uma lista com todos os registros de Medusozoa para o Brasil, incluindo informações sobre a distribuição das espécies e suas fases (pólipo ou medusa). O número de espécies de Medusozoa registradas para o Brasil até o momento é 377 (205 gêneros e 82 famílias), com 348 espécies de hidrozoários, 22 de cifozoários, 3 de cubozoários e 1 de estaurozoário. Análises geográfica e histórica também foram conduzidas. A análise geográfica mostra claramente a ausência de conhecimento sobre a biodiversidade da costa norte bem como de parte da costa nordeste do país. Embora a costa sudeste seja a melhor conhecida em termos de números de espécies e representantes de táxons supragenéricos registrados, há em geral ausência de conhecimento sobre ambientes diferentes das águas rasas, um padrão também observado para as outras regiões. Historicamente, o crescimento dos registros de hidrozoários iniciou-se após a década de 1940, com um aumento na última década; os estudos com coronados estão todos concentrados na última década mas, em geral, outros grupos mostram um acúmulo lento e gradual nos registros de espécies. Linhas gerais e políticas para o estudo da biodiversidade dos Medusozoa são sugeridas. cifozoários, cubozoários, estaurozoários, Fauna, Atlântico Sul, Pólipo, Medusa, Brasil Biota Neotropica v3 (n2) -http://www.biotaneotropica.org.br/v3n2/pt/abstract?inventory+BN01203022003 Palavras-chave:hidrozoários,
