The Role of Temperature in Survival of the Polyp Stage of the Tropical Rhizostome Jelly®Sh Cassiopea Xamachana
Journal of Experimental Marine Biology and Ecology, L 222 (1998) 79±91 The role of temperature in survival of the polyp stage of the tropical rhizostome jelly®sh Cassiopea xamachana William K. Fitt* , Kristin Costley Institute of Ecology, Bioscience 711, University of Georgia, Athens, GA 30602, USA Received 27 September 1996; received in revised form 21 April 1997; accepted 27 May 1997 Abstract The life cycle of the tropical jelly®sh Cassiopea xamachana involves alternation between a polyp ( 5 scyphistoma) and a medusa, the latter usually resting bell-down on a sand or mud substratum. The scyphistoma and newly strobilated medusa (5 ephyra) are found only during the summer and early fall in South Florida and not during the winter, while the medusae are found year around. New medusae originate as ephyrae, strobilated by the polyp, in late summer and fall. Laboratory experiments showed that nematocyst function, and the ability of larvae to settle and metamorphose change little during exposure to temperatures between 158C and up to 338C. However, tentacle length decreased and ability to transfer captured food to the mouth was disrupted at temperatures # 188C. Unlike temperate-zone species of scyphozoans, which usually over-winter in the polyp or podocyst form when medusae disappear, this tropical species has cold-sensitive scyphistomae and more temperature-tolerant medusae. 1998 Elsevier Science B.V. Keywords: Scyphozoa; Jelly®sh; Cassiopea; Temperature; Life history 1. Introduction The rhizostome medusae of Cassiopea xamachana are found throughout the Carib- bean Sea, with their northern limit of distribution on the southern tip of Florida. Unlike most scyphozoans these jelly®sh are seldom seen swimming, and instead lie pulsating bell-down on sandy or muddy substrata in mangroves or soft bottom bay habitats, giving rise to the common names ``mangrove jelly®sh'' or ``upside-down jelly®sh''. -
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. -

Population and Spatial Dynamics Mangrove Jellyfish Cassiopeia sp at Kenya’s Gazi Bay. American Journal of Life Sciences. Vol. 2, No. 6, 2014, pp. 395-399. doi: 10.11648/j.ajls.20140206.20 Abstract: Cassiopeia, the upside-down or mangrove jellyfish is a bottom-dwelling, shallow water marine sycophozoan of the phylum Cnidaria. It is commonly referred to as jellyfish because of its jelly like appearance. The medusa is the dominant phase in its life history. They have a radial symmetry and occur in shallow, tropical lagoons, mangrove swamps and sandy mud falls in tropical and temperate regions. In coastal Kenya, they are found only in one specific location in the Gazi Bay of the south coast. There are no documented studies on this species in Kenya. The objective of this study was to quantify the spatial and size-class distribution, and recruitment of Cassiopeia at the Gazi Bay. Ten 50mx50m quadrats were randomly placed in an estimated study area of 6.4ha to cover about 40 percent of the total study area. A total of 1043 individual upside-down jellyfish were sampled. In each quadrat, all jellyfish encountered were sampled individually. -

Two New Species of Box Jellies (Cnidaria: Cubozoa: Carybdeida)
RECORDS OF THE WESTERN AUSTRALIAN MUSEUM 29 010–019 (2014) DOI: 10.18195/issn.0312-3162.29(1).2014.010-019 Two new species of box jellies (Cnidaria: Cubozoa: Carybdeida) from the central coast of Western Australia, both presumed to cause Irukandji syndrome Lisa-Ann Gershwin CSIRO Marine and Atmospheric Research, Castray Esplanade, Hobart, Tasmania 7000, Australia. Email: [email protected] ABSTRACT – Irukandji jellies are of increasing interest as their stings are becoming more frequently reported around the world. Previously only two species were known from Western Australia, namely Carukia shinju Gershwin, 2005 and Malo maxima Gershwin, 2005, both from Broome. Two new species believed to cause Irukandji syndrome have recently been found and are described herein. One, Malo bella sp. nov., is from the Ningaloo Reef and Dampier Archipelago regions. It differs from its congeners in its small size at maturity, its statolith shape, irregular warts on the perradial lappets, and a unique combination of other traits outlined herein. This species is not associated with any particular stings, but its phylogenetic affi nity would suggest that it may be highly toxic. The second species, Keesingia gigas gen. et sp. nov., is from the Shark Bay and Ningaloo Reef regions. This enormous species is unique in possessing key characters of three families, including crescentic phacellae and broadly winged pedalia (Alatinidae) and deeply incised rhopalial niches and feathery diverticulations on the velarial canals (Carukiidae and Tamoyidae). These two new species bring the total species known or believed to cause Irukandji syndrome to at least 16. Research into the biology and ecology of these species should be considered a high priority, in order to manage their potential impacts on public safety. -

Therefore, an inclusive study on jellyfish was carried out from November 2016 to July 2019 for taxonomic identification of the species found in coastal waters. In this study, three species of cepheid mild stingers, Cephea cephea, Marivagia stellata, and Netrostoma setouchianum were reported for the first time in Sri Lankan waters. Moreover, the diagnostic description of the genus Marivagia is revised in this study due to the possessing of appendages on both oral arms and arm disc of Sri Lankan specimens, comparing with original notes and photographs of M. stellata.

Cnidarian Phylogenetic Relationships As Revealed by Mitogenomics Ehsan Kayal1,2*, Béatrice Roure3, Hervé Philippe3, Allen G Collins4 and Dennis V Lavrov1
Kayal et al. BMC Evolutionary Biology 2013, 13:5 http://www.biomedcentral.com/1471-2148/13/5 RESEARCH ARTICLE Open Access Cnidarian phylogenetic relationships as revealed by mitogenomics Ehsan Kayal1,2*, Béatrice Roure3, Hervé Philippe3, Allen G Collins4 and Dennis V Lavrov1 Abstract Background: Cnidaria (corals, sea anemones, hydroids, jellyfish) is a phylum of relatively simple aquatic animals characterized by the presence of the cnidocyst: a cell containing a giant capsular organelle with an eversible tubule (cnida). Species within Cnidaria have life cycles that involve one or both of the two distinct body forms, a typically benthic polyp, which may or may not be colonial, and a typically pelagic mostly solitary medusa. The currently accepted taxonomic scheme subdivides Cnidaria into two main assemblages: Anthozoa (Hexacorallia + Octocorallia) – cnidarians with a reproductive polyp and the absence of a medusa stage – and Medusozoa (Cubozoa, Hydrozoa, Scyphozoa, Staurozoa) – cnidarians that usually possess a reproductive medusa stage. Hypothesized relationships among these taxa greatly impact interpretations of cnidarian character evolution. Results: We expanded the sampling of cnidarian mitochondrial genomes, particularly from Medusozoa, to reevaluate phylogenetic relationships within Cnidaria. Our phylogenetic analyses based on a mitochogenomic dataset support many prior hypotheses, including monophyly of Hexacorallia, Octocorallia, Medusozoa, Cubozoa, Staurozoa, Hydrozoa, Carybdeida, Chirodropida, and Hydroidolina, but reject the monophyly of Anthozoa, indicating that the Octocorallia + Medusozoa relationship is not the result of sampling bias, as proposed earlier. Further, our analyses contradict Scyphozoa [Discomedusae + Coronatae], Acraspeda [Cubozoa + Scyphozoa], as well as the hypothesis that Staurozoa is the sister group to all the other medusozoans. Conclusions: Cnidarian mitochondrial genomic data contain phylogenetic signal informative for understanding the evolutionary history of this phylum. -
Scyphozoa: Rhizostomeae: Cepheidae) from the Lebanese Waters in the Eastern Mediterranean Sea
J. Black Sea/Mediterranean Environment Vol. 25, No. 2: 172-177 (2019) SHORT COMMUNICATION First record of Marivagia stellata Galil and Gershwin, 2010 (Scyphozoa: Rhizostomeae: Cepheidae) from the Lebanese waters in the eastern Mediterranean Sea Ghazi Bitar *, Ali Badreddine Department of Marine Biology, Faculty of Sciences, Lebanese University, Hadath, Beirut, LEBANON *Corresponding author: [email protected] Abstract Marivagia stellata Galil and Gershwin, 2010 was reported for the first time from the Lebanese waters in the eastern Mediterranean Sea. This Indo-Pacific jellyfish was observed in 2015 during a field work. The present note reports its details in the Lebanese waters. Keywords: Indo-Pacific jellyfish, Marivagia stellata, Lebanese waters Received: 29.05.2019, Accepted: 29.06.2019 The Mediterranean Sea is severely affected by alien species: 986 exotic species are recorded in this basin, representing 6% of the total number of species. Interestingly, 775 of them are established in the eastern basin, mostly (88.4 %) from the Indo-Pacific and tropical Atlantic, and 108 are considered as invasive (Zenetos et al. 2010; 2012). In particular, new invasions of jellyfish are increasingly reported in the Mediterranean Sea in recent years: 13 invasive species which represent 3% of the known jellyfish species in the Mediterranean Sea were reported (Brotz and Pauly 2012; Mizrahi et al. 2015; Oztürk et al. 2018; Mamish et al. 2019). Since the opening of the Suez Canal, the Lebanese waters have been colonized by many exotic species, especially from the Red Sea. Concerning jellyfish, two lessepsian species have been recorded in the Lebanese waters (Lakkis 2013): Rhopilema nomadica (Brotz and Pauly 2012) and Cassiopea andromeda (Forsskål, 1775). -
