E-mail: [email protected] Received: 07 December 2016/Accepted: 20 December 2016/ Published: 29 December 2016 Abstract: Marine organisms are a rich source of natural products with potential secondary metabolites that have great pharmacological activity. Starfish are known as by-catch products in the worldwide fishing industry and most of starfish have been got rid of by fire destruction without any utilization. On the other hand, starfish are considered as extremely rich sources of biological active compounds in terms of having pharmacological activity. In the present study, molecular identification of starfish species, micronutrient content and hemolytic activity from Luidia quinaria, Astropecten scoparius, and Patiria pectinifera were examined. Nucleotide sequence analysis of the 16S rRNA gene fragment of mitochondrial DNA indicated that partial sequences of PCR products of the species was identical with that of L. quinaria, A. scoparius, and P. pectinifera. From the results of micronutrient contents, there were no great differences on the micronutrient among species. -

Fine Structure of the Podia in Three Species of Paxillosid Asteroids of the Genus Lu/Dia (Echinodermata)
Belg. J. Zool. - Volume 125 (1995) - issue 1 - pages 125-134 - Brussels 1995 FINE STRUCTURE OF THE PODIA IN THREE SPECIES OF PAXILLOSID ASTEROIDS OF THE GENUS LU/DIA (ECHINODERMATA) by PATRICK FLAMMANG * La boratoire de Biologie Marine, Université de Mons-Hainaut, 19 av. Maistriau, B-7000 Mons, Belgium SUMMARY lndividuals of the paxillosid asteroid genus Luidia use their podia in locomotion a nd burrowing. Each podium in the three considered species consists of a stem wi tb a pointed knob at its tip. The knob consists of four tissue layers that are, from the inside to the outside, a mesothelium, a connective ti ss ue layer, a nerve plexus, and an epidermis. The latter is made up of four cell categories : secretory cells, neurosecretory cells, non-secretory cili ated cell s, and support cells. The epidermal cells of the podial knob are presumabl y fun ctioning as a duo gland adhesive system in which adhesive secretions would be produced by secretory cell s wh ile de-adhesion, on the other band, would be due to neurosecretory cell secretions. Although the podia of the three considered species of Luidia share numerous simjlarities, there are nevertheless severa! important morphological differences between, on the one band, the podia of L. ciliaris and L. maculata, and, on the other band, the podia of L. penangensis. These dif ferences stress that carefulness is required when ge n e r a lj zat ion ~, drawn from the morphology of a single species, are applied to related species havin g the sa me ]jfe style ; but also that the gem1s Luidia needs to be re-exa mined from a taxonomjc p-o int of view. -

ZooKeys 185: 73–78. doi: 10.3897/zookeys.185.3078 Abstract This dataset includes information on sea stars collected during the ANDEEP3 expedition, which took place in 2005. The expedition focused on deep-sea stations in the Powell Basin and Weddell Sea. Sea stars were collected using an Agassiz trawl (3m, mesh-size 500µm), deployed in 16 stations during the ANTXXII/3 (ANDEEP3, PS72) expedition of the RV Polarstern. Sampling depth ranged from 1047 to 4931m. Trawling distance ranged from 731 to 3841m. The sampling area ranges from -41°S to -71°S (latitude) and from 0 to -65°W (longitude). A complete list of stations is available from the PANGAEA data system (http://www.pangaea.de/PHP/CruiseReports.php?b=Polarstern), including a cruise report (http://epic-reports.awi.de/3694/1/PE_72.pdf). The dataset includes 50 records, with individual counts ranging from 1-10, reaching a total of 132 specimens. -
New Species, Corallivory, in Situ Video Observations and Overview of the Goniasteridae (Valvatida, Asteroidea) in the Hawaiian Region

MAH Dept. of Invertebrate Zoology, Smithsonian Institution, Washington, D.C. 20007 Abstract Two new species of Goniasteridae, Astroceramus eldredgei n. sp. and Apollonaster kelleyi n. sp. are described from the Hawaiian Islands region. Prior to this occurrence, Apollonaster was known only from the North Atlantic. The Goniasteri- dae is the most diverse family of asteroids in the Hawaiian region. Additional in situ observations of several goniasterid species, including A. eldredgei n. sp. are reported. These observations extend documentation of deep-sea corallivory among goniasterid asteroids. New species occurrences presented herein suggested further biogeographic affinities be- tween tropical Pacific and Atlantic goniasterid faunas. Key words: Goniasteridae, Valvatida, deep-sea, Hawaiian Islands, predation Introduction Recent discoveries of new genera and species from deep-sea habitats along with new in situ video observations have provided us with new ecological insight into these poorly understood and formerly inaccessible settings (e.g., Mah et al. 2010, 2014; Mah & Foltz 2014). Hawaiian deep-sea Asteroidea are taxonomically diverse and occur in an active area of oceanographic and biological research (Chave and Malahoff 1998). New data on asteroids in this area presents an opportunity to review and highlight this diverse fauna. -
Sulphated Saponins from the Starfish Luidia Senegalensis Collected As By-Catch Fauna
SULPHATED SAPONINS FROM THE STARFISH LUIDIA SENEGALENSIS COLLECTED AS BY-CATCH FAUNA Marcelo M.P. Tangerina, Júlia P. Cesário, Gerson R.R. Pereira, Tânia M. Costa, Wagner C. Valenti and Wagner Vilegas UNESP- Paulista State University, Paulista Coastal Campus , Praça Infante Dom Henrique s/n, São Vicente, São Paulo, CEP: 11330-900, Brazil. [email protected] Abstract: The by-catch fauna of the shrimp fishery includes a number of marine invertebrates that are discarded because they do not have commercial value. In order to try to add some value to these materials, we analyzed the chemical composition of the starfish Luidia senegalensis (Luidiidae, Asteroidea: Paxillosida) collected in the Brazilian coast as a consequence of the trawling fishery method. In order to access their chemical composition, we used a combination of solid phase extraction (SPE) followed by ultra high performance liquid chromatography coupled to electrospray ionization ion trap tandem mass spectrometry (UPLC-ESI-IT-MS n). Luidia spp. contains mainly asterosaponins, which are the glycosides derived from the polyhydroxysteroids. Four asterosaponins found in L. senegalensis present a ∆9,11 -3β,6 α- steroidal core, with four rings, a sulphate group at C3, one oxo group at the side chain, and five or six sugar moieties attached to C-6 (Aglycone 1) [C 62 H101 O33 SNa MW 1428; C 62 H101 O32 SNa MW 1412; 24,25 C56 H91 O27 SNa MW 1250 (two isomers)]; a fifth saponin presented an additional double bond at ∆ (Aglycone 2) [C 55 H87 O27 SNa MW 1262]. Sulphated steroidal saponins present several biological activities, like hemolytic, antineoplastic, cytotoxic, antitumor, antibacterial, antiviral antifungal and anti-inflammatory [1]. -

John W.M. Jagt, Natuurhistorisch Museum Maastricht, Postbus 882, NL-6200 AW Maastricht, The Netherlands, E-mail: [email protected] Key words: Echinodermata, Late Cretaceous, Early Palaeogene, palaeobiology, K/T boundary, extinc- tion. The palaeobiology of echinoderms occurring in the Meerssen and Geulhem members is discussed and changes in diversity across the K/T boundary are documented. Using literature data on the ecology of extant faunas, the various echinoderm groups are considered. Naturally, such data can only be applied with due caution to fossil forms, whose skeletal morphology is often incompletely known. This holds especially true for asteroids, ophiuroids, and crinoids, which, upon death, rapidly disinte- grate into jumbles of dissociated ossicles. Bioturbation, scavenging, and current winnowing all con- tribute to blurring the picture still further. However, data on extant forms do allow a preliminary sub- division of fossil species into various ecological groups, which are discussed herein. Combining recently published data on K/T boundary sections in Jylland and Sjælland (Denmark) with the pic- ture drawn here for the Maastricht area results in the following best constrained scenario. The demise of the highly diverse latest Maastrichtian echinoderm faunas, typical of shallow-water settings with local palaeorelief and associated unconsolidated bottoms, was rapid, suggestive of a catastrophic event (e.g. -

As humans, we interact with sea stars when they are used as research animals or displayed at public or private aquaria. Molecular research requires fresh tissues that have thus far been considered to be of the best quality if collected without euthanasia. This is the first paper describing a method to euthanize sea stars that still allows for sampling of high-quality tissue that can be used for advanced research. Since it can be difficult to tell if an invertebrate has died, it is important to use a two-step method where the first step makes it non-responsive and Citation: Wahltinez, S.J.; Kroll, K.J.; the next step ensures it has died.
