Kumavath - Email: [email protected]; *Corresponding author Received August 14, 2014; Accepted August 16, 2014; Published September 30, 2014 Abstract: Turritopsis nutricula (T. nutricula) is the one of the known reported organisms that can revert its life cycle to the polyp stage even after becoming sexually mature, defining itself as the only immortal organism in the animal kingdom. Therefore, the animal is having prime importance in basic biological, aging, and biomedical researches. However, till date, the genome of this organism has not been sequenced and even there is no molecular phylogenetic study to reveal its close relatives. Here, using phylogenetic analysis based on available 16s rRNA gene and protein sequences of Cytochrome oxidase subunit-I (COI or COX1) of T. nutricula, we have predicted the closest relatives of the organism. While we found Nemopsis bachei could be closest organism based on COX1 gene sequence; T. dohrnii may be designated as the closest taxon to T.

The seasonal abundance and distribution of the dominant species of hydromedusae along a salinity gradient within the Gironde Estuary, Atlantic coast of France, were evaluated based on monthly surveys, June 2013 to April 2014. The results confirmed the presence of three species considered to be introduced in many coastal ecosystems around the world: Nemopsis bachei (Agassiz, 1849), Blackfordia virginica (Mayer, 1910), and Maeotias marginata (Modeer, 1791). These species were found at salinities ranging from 0 to 22.9 and temperatures ranging from 14.5 to 26.6 ºC, demonstrating their tolerance to a wide range of estuarine environmental conditions.

The first was discovered on November 2014, on Getares Beach (Algeciras Bay, Mediterranean part of the Strait of Gibraltar), where more than 700 colonies were found deposited along the tideline. The second event was discovered on January 2015, on Paloma Baja Beach (Tarifa, Atlantic part of the Strait of Gibraltar) where an average density of 170 colonies m−2 was spread along the seashore. Both events seemed to be promoted by strong easterly winds, preceded by upwelling episodes that may have concentrated high densities of the siphonophore in superficial layers. This study represents the first report of a calycophoran siphonophore mass stranding. The records were made thanks to citizen science and jellyfish outreach at secondary schools (PERSEUS@school initiative), illustrating the importance of citizen science projects in observing natural phenomena. We consider the monitoring and recording of cnidarian stranding events especially important in highly productive and biologically active areas such as the Strait of Gibraltar. Keywords Mass stranding . Gelatinous zooplankton . Citizen science . Outreach . Secondary schools Introduction abundant epipelagic siphonophore inhabitant of temperate and warm waters of the Atlantic, Pacific and Indican oceans Siphonophores are long pelagic colonial hydrozoans and the Mediterranean Sea (Alvariño 1971; Mapstone 2014).

About 700 plankton samples were taken from estuarine and oceanic areas. From these samples, 26 species of hydromedusae were identified, 12 of which were collected from Mis- sissippi Sound. In addition, 25 species of siphonophorae were identified from Mississippi waters, although only 6 species were collected in Mississippi Sound. From an examination of about 500 trawl samples taken during this period, 10 species of Scyphozoa were found in Mississippi waters, 6 of which occurred in Mississippi Sound.

However, bacteria associated with different life stages of Scyphozoa have received less attention. In this study, bacterial communities associated with different body compartments and different life stages of two common scyphomedusae (Cyanea lamarckii and Chrysaora hysoscella) were analyzed via automated ribosomal intergenic spacer analysis (ARISA). We found that the bacterial community associated with these two species showed species- specific structuring. In addition, we observed significant differences between the bacterial communities associated with the umbrella and other body compartments (gonads and tentacles) of the two scyphomedusan species. Bacterial commu- nity structure varied from the early planula to the polyp and adult medusa stages. We also found that the free-living and particle-associated bacterial communities associated with different food sources had no impact on the bacterial community associated with fed polyps.
