Medusa Catostylus Tagi: (I) Preliminary Studies on Morphology, Chemical Composition, Bioluminescence and Antioxidant Activity
MEDUSA CATOSTYLUS TAGI: (I) PRELIMINARY STUDIES ON MORPHOLOGY, CHEMICAL COMPOSITION, BIOLUMINESCENCE AND ANTIOXIDANT ACTIVITY Ana Maria PINTÃO, Inês Matos COSTA, José Carlos GOUVEIA, Ana Rita MADEIRA, Zilda Braga MORAIS Centro de Polímeros Biomédicos, Cooperativa Egas Moniz, Campus Universitário Quinta da Granja, 2829-511, Portugal, [email protected] The Portuguese continental coast, specially Tejo and Sado estuaries, is the habitat of Catostylus tagi [1]. This barely studied medusa was first described in 1869, by Haeckel, and is classified in the Cnidaria phylum, Scyphozoa class, Rhizostomeae order, Catostylidae family, Catostylus genus. According to the European Register of Marine Species, the referred medusa is the only species of the Catostylidae family found in the European continent [2]. C. tagi is particularly abundant during the summer. Several medusas from the Rhizostomae order are traditionally used as food in some oriental countries [3]. Simultaneously, modern medusa utilizations are related to bioluminescence [4], toxicology [5] and biopolymers [6]. The lack of information on this genus along with the recent discoveries of new marine molecules showing anti-arthritic, anti-inflammatory or antioxidant properties motivated our studies [7]. In addition, the abundant medusa biomass could be evaluated as another natural collagen source, alternative to bovine collagen, with its multiple cosmetic and surgical potential uses [8]. The capture and sample preparation methods were optimized in 2003 [9]. Results reported in this poster relate to 65 animals that were captured in the river Sado in August and September of 2004. Macroscopic aspects, like mass and dimensions, were evaluated as well as their C. tagi by J.Gouveia chemical characteristics. -

This study identified the putative toxins of two species of jellyfish—edible jellyfish Rhopilema esculentum Kishinouye, 1891, also known as flame jellyfish, and Amuska jellyfish Sanderia malayensis Goette, 1886. Utilizing nano-flow liquid chromatography tandem mass spectrometry (nLC–MS/MS), 3000 proteins were identified from the nematocysts in each of the above two jellyfish species. Forty and fifty-one putative toxins were identified in R. esculentum and S. malayensis, respectively, which were further classified into eight toxin families according to their predicted functions. Amongst the identified putative toxins, hemostasis-impairing toxins and proteases were found to be the most dominant members (>60%). -

Hidrobiológica 23 (2): 218-226. ABSTRACT The cannonball jellyfish (S. meleagris) has reached production levels that has led it to become an important fishery resource in Las Guásimas, Sonora, a coastal lagoon in northwestern Mexico; however, its ecological importance and role in the ecosystem remain unstudied. This contribution describes the diet composition of this species in order to reveal its trophic importance in this coastal lagoon. Up to 17 jellyfish were captured in each of three surveys (March 2008, February and April 2009), their stomachs were extracted and analyzed to determine their diet composition. The quantitative methods: frequency of occurrence (F), numeric (N), gravimetric (W) and the index of relative importance, were used to measure the diet components, and Levin´s index to measure the diet amplitude. -

THE SYSTEMATIC POSITION OF THE Title STAUROMEDUSAE Author(s) Uchida, Tohru PUBLICATIONS OF THE SETO MARINE BIOLOGICAL Citation LABORATORY (1973), 20: 133-139 Issue Date 1973-12-19 URL http://hdl.handle.net/2433/175784 Right Type Departmental Bulletin Paper Textversion publisher Kyoto University THE SYSTEMATIC POSITION OF THE STAUROMEDUSAE ToHRU UCHIDA Biological Laboratory, Imperial Household, Tokyo With 2 Text-figures The Stauromedusae have hitherto been referred together with the Cubomedusae to the subclass Scyphostomidae in the Scyphomedusae. Recently, however, the life cycle of the cubomedusa, Tripedalia cystophora became clear by WERNER, CuTRESS and STUDEBACKER (1971) and it was established that the Cubomedusae only stand in a quite separate position from other orders of Scyphomedusae. On the other hand, WERNER who published several papers on the Scyphozoan polyp, Stephanoscyphus (1966-1971) laid stress on the fact that Stephanoscyphus can be linked directly with the extinct fossil group of the Conulata and concluded that the Coronatae represent the most basic group of all living Scyphomedusae with the exception of Cubomedusae. Such being the case, the systematic position of the Stauromedusae remains proble matical. The present writer is of the opinion that the Stauromedusae are to be entitled to the Ephyridae and are closely related to the Discomedusae, though there occurs no strobilation in the order. The body of Stauromedusae is composed of two parts; the upper octomerous medusan part and the lower tetramerous scyphistoma portion. No strobilation and no ephyra. Throughout their life history, they lack pelagic life entirely; an egg develops to the solid blastula, which becomes to the planula. -

Abstract: Spatial and temporal abundance and distribution of Stomolophus meleagris (Rhizostomae: Stomolophidae) in a lagoon system Southern Gulf of Mexico. The scyphomedusae feed mainly on micro- scopic crustaceans, eggs and fish larvae, molluscs and some other jellyfishes. The distribution and abundance of the scyphomedusae has an economic and ecological impact as they are predators that have an influence on the population dynamics of other fisheries. This investigation took place in the lagoon system ‘Arrastradero- Redonda’, Tabasco, from September 2013 to August 2014, with the purpose to provide information on the distri- bution, and spatial and temporal abundance of Stomolophus meleagris; along with its relation to environmental parameters. A total of 10 stations were defined and biological samples were taken on a monthly basis during this annual cycle. For this purpose, three pulls with a beach seine monofilament (20 m long by 3 m height, mesh opening 1.5 cm, 5 to 10 minutes) per station were made within a 1 km2 area. -

Population Structures and Levels of Connectivity for Scyphozoan and Cubozoan Jellyfish
diversity Review Population Structures and Levels of Connectivity for Scyphozoan and Cubozoan Jellyfish Michael J. Kingsford * , Jodie A. Schlaefer and Scott J. Morrissey Marine Biology and Aquaculture, College of Science and Engineering and ARC Centre of Excellence for Coral Reef Studies, James Cook University, Townsville, QLD 4811, Australia; [email protected] (J.A.S.); [email protected] (S.J.M.) * Correspondence: [email protected] Abstract: Understanding the hierarchy of populations from the scale of metapopulations to mesopop- ulations and member local populations is fundamental to understanding the population dynamics of any species. Jellyfish by definition are planktonic and it would be assumed that connectivity would be high among local populations, and that populations would minimally vary in both ecological and genetic clade-level differences over broad spatial scales (i.e., hundreds to thousands of km). Although data exists on the connectivity of scyphozoan jellyfish, there are few data on cubozoans. Cubozoans are capable swimmers and have more complex and sophisticated visual abilities than scyphozoans. We predict, therefore, that cubozoans have the potential to have finer spatial scale differences in population structure than their relatives, the scyphozoans. Here we review the data available on the population structures of scyphozoans and what is known about cubozoans. The evidence from realized connectivity and estimates of potential connectivity for scyphozoans indicates the following. Some jellyfish taxa have a large metapopulation and very large stocks (>1000 s of km), while others have clade-level differences on the scale of tens of km.

Bioinvasions in the Mediterranean Sea 2 7
Metamorphoses: Bioinvasions in the Mediterranean Sea 2 7 B. S. Galil and Menachem Goren Abstract Six hundred and eighty alien marine multicellular species have been recorded in the Mediterranean Sea, with many establishing viable populations and dispersing along its coastline. A brief history of bioinvasions research in the Mediterranean Sea is presented. Particular attention is paid to gelatinous invasive species: the temporal and spatial spread of four alien scyphozoans and two alien ctenophores is outlined. We highlight few of the dis- cernible, and sometimes dramatic, physical alterations to habitats associated with invasive aliens in the Mediterranean littoral, as well as food web interactions of alien and native fi sh. The propagule pressure driving the Erythraean invasion is powerful in the establishment and spread of alien species in the eastern and central Mediterranean. The implications of the enlargement of Suez Canal, refl ecting patterns in global trade and economy, are briefl y discussed.

Abstract For the entire Brazilian coast, there are 22 published records of scyphozoans. On the other hand, only 35 species of cubozoans were described worldwide, four of them reported for the Brazilian coast. However, little is known about the species of cubozoans and scyphozoans in the Northeastern states of Brazil. The aim of this study was to perform a survey of the jellyfish (Cnidaria: Cubozoa and Scyphozoa) on the coast of Rio Grande do Norte state, Northeast of Brazil. Specimens were collected using trawl net on beaches in the counties of Natal (in 2003) and Tibaú (in 2004). For the Rio Grande do Norte coast there were few records of large jellyfish, and new records of the following cubozoan and scyphozoan species were verified: Chiropsalmus quadrumanus; Chrysaora lactea; Lychnorhiza lucerna and Stomolophus meleagris. -

Morphological analysis of several specimens showed distinct differences from other known semaestome spe- cies in the Mediterranean Sea and unquestionably identified them as belonging to a new pelagiid species within genus Pelagia. The new species is morphologically distinct from P. noctiluca, currently the only recognized valid species in the genus, and from other doubtful Pelagia species recorded from other areas of the world. Molecular analyses of mitochon- drial cytochrome c oxidase subunit I (COI) and nuclear 28S ribosomal DNA genes corroborate its specific distinction from P. noctiluca and other pelagiid taxa, supporting the monophyly of Pelagiidae. Thus, we describe Pelagia benovici sp.
