We have compiled available records in the literature for medusozoan cnidarians and ctenophores of South America. New species are also included. Each entry (i.e., identified or still as yet not determined referred to "sp." literature) includes a synonymy list America, taxonomical remarks, notes on habit, information geographical occurrence. listed 800 unique species, 958 morphotype entries: 5 cubozoans, 905 hydrozoans, 25 scyphozoans, 3 staurozoans, 20 ctenophores. Concerning nomenclatural...
While records of Carybdea marsupialis in the literature suggest a worldwide distribution this species, validity some these has been questioned recently, as nominal species. We inspected material all known species from multiple locations (i.e. Spain, Algeria, Tunisia, Puerto Rico, California, Hawaii, Australia, South Africa, and Japan) using morphological genetic tools to differentiate well understand their evolutionary relationships. observed differences between adult medusae Mediterranean...
The upside-down jellyfish Cassiopea xamachana (Scyphozoa: Rhizostomeae) has been predominantly studied to understand its interaction with the endosymbiotic dinoflagellate algae Symbiodinium. As an easily culturable and tractable cnidarian model, it is attractive alternative stony corals understanding mechanisms driving establishment maintenance of symbiosis. also unique in requiring symbiont order complete transition adult stage, thereby providing excellent model symbiosis-driven development...
The low evolutionary rate of mitochondrial genes in Anthozoa has challenged their utility for phylogenetic and systematic purposes, especially DNA barcoding. However, the Ceriantharia, one most enigmatic "orders" within Anthozoa, never been specifically examined. In this study, divergence Ceriantharia was compared to members other Medusozoa groups. addition, nuclear markers were used check relative position relation Cnidaria members. results demonstrated a pattern completely different from...
Upside-down jellyfish (genus Cassiopea ) can be found in tropical coastal waters worldwide. Until now reports of the genus from Brazilian have been scant. We report here medusae and scyphistomae collected Cabo Frio, Rio de Janeiro state. Although we could not unambiguously identify material using morphological criteria, genetic sequence data (COI) indicate that jellyfishes are genetically similar to those Bermuda, Hawaii Florida, which related specimens Red Sea ( andromeda ). hypothesize...
Cryptic species have been detected across Metazoa, and while no apparent morphological features distinguish them, it should not impede taxonomists from formal descriptions. We accepted this challenge for the jellyfish genus
A new species of Pachycerianthus (Cnidaria: Ceriantharia) is described from the Brazilian coast southwestern Atlantic Ocean. schlenzae sp. nov. found in fine sand or mud shallow waters Abrolhos and Royal Charlotte Bank. The only known this area most notably different other genus mesentery arrangement cnidome. In addition to description, we provide some biological data collected individuals cultivated under laboratory conditions.
Cnidarians are critical members of aquatic communities and have been an experimental system for a diversity research areas ranging from development to biomechanics global change biology. Yet, we still lack well-resolved, taxonomically balanced cnidarian tree life place this in appropriate phylogenetic context. To move towards goal, combined data 26 new anthozoan transcriptomes with 86 previously published outgroup datasets generate two 748-locus alignments containing 123,051 (trimmed)...
The use of molecular data for species delimitation in Anthozoa is still a very delicate issue. This probably due to the low genetic variation found among markers (primarily mitochondrial) commonly used Anthozoa. Ceriantharia an anthozoan group that has not been tested divergence at level. Recently, all three Atlantic described genus Isarachnanthus Ocean, were deemed synonyms based on morphological simmilarities only one species: maderensis. Here, we aimed verify whether relationships (using...
Tube anemones, or cerianthids, are a phylogenetically informative group of cnidarians with complex life histories, including pelagic larval stage and tube-dwelling adult stage, both known to utilize venom in stinging-cell rich tentacles. Cnidarians an entirely venomous that their proteinaceous-dominated toxins capture prey defend against predators, addition several other ecological functions, intraspecific interactions. At present there no studies describing the for any species within...
Abstract Sequences and structural attributes of mitochondrial genomes have played a critical role in the clarification relationships among Cnidaria, key phylum early-diverging animals. Among major lineages Ceriantharia (“tube anemones”) remains one most enigmatic terms its phylogenetic position. We sequenced two ceriantharians to see whether complete organellar genome would provide more support for placement Ceriantharia. For both Isarachnanthus nocturnus Pachycerianthus magnus , gene...
Abstract Aim Knowledge gaps and sampling bias can lead to underestimations of species richness distortions in the known distribution species. The goal this study is identify potential biases marine organisms at Western Atlantic Ocean, determine their causes assess its effect on biodiversity metrics. We tested interference with representation environmental conditions, potentially affecting model predictions. Location Ocean. Methods This compiled data online institutional databases. analysis...
As espécies de Cubozoa e Scyphozoa costeiras que ocorrem no Brasil são descritas, com base em espécimes coleções museus exemplares recém-coletados. Chaves identificação um glossário também apresentados. descritas são: Aurelia sp.; Cassiopea xamachana Bigelow, 1892; Chiropsalmus quadrumanus (Müller, 1859); Chrysaora lactea Eschscholtz, 1829; Drymonema dalmatinum Haeckel, 1880; Linuche unguiculata (Swartz, 1788); Lychnorhiza lucerna Nausithoe aurea Silveira & Morandini, 1997; Phyllorhiza...
Abstract A new species of box jellyfish, Copula lucentia sp. nov., is described from El Campello, Spain, and compared to the holotype sivickisi that was successfully recovered after being lost for almost 60 years. So far, only cubozoan recorded in Western Mediterranean Carybdea marsupialis . The genus just included type ( ) reported different localities Pacific, Atlantic, Indian Oceans. Morphologically, this possesses typical characteristics (four adhesive pads on apex a vertical...
A recent study proposed an unorthodox view of the long-known metagenetic life cycle scyphozoan jellyfish.We argue that misinterpretations and imprecise information generated a misleading such patterns.In favor our reasoning, we present historical understanding metagenesis, contend it can still be used as shared general pattern for Scyphozoa, well other medusozoans.Recently, Ceh et al. (2015) published presenting particular classic longstanding "model" alternation generations jellyfishes...
This study provides the first observation that umbrellar tissue can lead to formation of virtually all body structures in jellyfish order Rhizostomeae. The regeneration process was observed two specimens upside-down
The massive occurrence of jellyfish in several areas the world is reported annually, but most data come from northern hemisphere and often refer to a restricted group species that are not genus Cassiopea . This study records massive, clonal non-native population discusses possible scenarios resulted invasion Brazilian coast by these organisms. results indicate this might have invaded multiple times.
