Review Article Published: 17 Sep, 2018 SF Journal of Biotechnology and Biomedical Engineering The Sea Stars (Echinodermata: Asteroidea): Their Biology, Ecology, Evolution and Utilization Rahman MA1*, Molla MHR1, Megwalu FO1, Asare OE1, Tchoundi A1, Shaikh MM1 and Jahan B2 1World Fisheries University Pilot Programme, Pukyong National University (PKNU), Nam-gu, Busan, Korea 2Biotechnology and Genetic Engineering Discipline, Khulna University, Khulna, Bangladesh Abstract The Sea stars (Asteroidea: Echinodermata) are comprising of a large and diverse groups of sessile marine invertebrates having seven extant orders such as Brisingida, Forcipulatida, Notomyotida, Paxillosida, Spinulosida, Valvatida and Velatida and two extinct one such as Calliasterellidae and Trichasteropsida. Around 1,500 living species of starfish occur on the seabed in all the world's oceans, from the tropics to subzero polar waters. They are found from the intertidal zone down to abyssal depths, 6,000m below the surface. Starfish typically have a central disc and five arms, though some species have a larger number of arms. The aboral or upper surface may be smooth, granular or spiny, and is covered with overlapping plates. -

Echinoderms have no well-defined eyes but several opsin genes were found in the purple sea urchin (Strongylocentrotus purpuratus) genome. Molecular data are lacking for other echinoderm classes although many species are known to be light sensitive. Results: In this study focused on the European brittle star Amphiura filiformis, we first highlighted a blue-green light sensitivity using a behavioural approach. We then identified 13 new putative opsin genes against eight bona fide opsin genes in the genome of S. purpuratus. Six opsins were included in the rhabdomeric opsin group (r-opsins). In addition, one putative ciliary opsin (c-opsin), showing high similarity with the c-opsin of S. purpuratus (Sp-opsin 1), one Go opsin similar to Sp-opsins 3.1 and 3.2, two basal-branch opsins similar to Sp-opsins 2 and 5, and two neuropsins similar to Sp-opsin 8, were identified. Finally, two sequences from one putative RGR opsin similar to Sp-opsin 7 were also detected. Adult arm transcriptome analysis pinpointed opsin mRNAs corresponding to one r-opsin, one neuropsin and the homologue of Sp-opsin 2. -

The latter is raised to specific rank. Analysis of mitochondrial DNA supports the concept of a pan-tropical assemblage of species for which a new genus, Cryptasterina, is created. All species in Cryptaster- ina are morphologically similar and comprise species with planktonic, lecithotrophic, non-feeding larvae, and viviparous outlier species with limited distributions. The full diversity of this species diaspora remains to be resolved.

Barker, Philip V. Mladenov Department of Marine Science, University of Otago, PO Box 56, Dunedin, New Zealand ABSTRACT: Populations of the fissiparous seastar Coscinasterias muricata were surveyed around New Zealand to determine the frequency of asexual reproduction. Seastars from an intertidal popula- tion from the Maori Bay (North Island) and 2 shallow subtidal-intertidal sites in Otago Harbour on the east coast of the South Island had split, were asymmetrical, had multiple madreporites and skewed sex ratios when gonads were present. In contrast, none of the populations from 13 subtidal populations from the fjords on the west coast or a subtidal population from Stewart Island had characters indicat- ing that they had recently split. Examination of genetic diversity using allozymes agreed with mor- phological interpretations; the populations from the Maori Bay and the east coast (Otago Harbour) had significantly lower genotypic diversity than expected, while the fjord populations had genotypic diversity that conformed to expectations under sexual outcrossing. We investigated the effects of food supply and fluctuating temperature on growth, energy storage, gonad development and fission of C. muricata from a fissiparous population in Otago Harbour. Growth, gonad development and the py- loric caeca index increased with increased food supply. No effects were found due to the fluctuating temperature regime. Fission occurred in all treatments except when the seastars were starving, as in- dicated by decrease in size. -

Perrier. 1878. Étude sur la repartition géographique des astérides. Nouvelles Archives du Muséum d’Histoire Naturelle. Paris. Second Series, Volume 1. 1–108. Translator’s Note Perrier’s work is based on the taxonomic designation of families, genera and species at that period. That taxonomy now obsolete. Perrier frequently noted misidentifications, duplications, and inadequate descriptions of species and lack of collections in many regions. He stated that future work would result in many changes. The work is of historical interest because it indicates the state of asteroid taxonomy and knowledge of asteroid distribution in the latter half of the nineteenth century. I have retained Perrier’s spelling of taxonomic names. -

Diseases of Echinodermata. 111. Agents Metazoans (Annelida to Pisces)
l DISEASES OF AQUATIC ORGANISMS Vol. 3: 59-83, 1987 Published October 14 Dis. aquat. Org. REVIEW Diseases of Echinodermata. 111. Agents metazoans (Annelida to Pisces) Michel Jangoux Laboratoire de Biologie marine (CP 160),Universite Libre de Bruxelles, Ave F. D. Roosevelt 50, B-1050 Bruxelles, Belgium ABSTRACT. Parasitic myzostomids mostly infest crinoids but a few are known from asteroids and ophiuroids; they are either galhcole, cysticole or endoparasitic. Although many copepods have been said to be ectoparasitic on echinoderms, this has been proven for only a few species. Some copepods are known to induce gall formation in the spines of echinoids or in the body wall of ophiuroids; others have been found to infest either the bursae or gonads of ophiuroids. Ascothoracid cirripeds were reported either as ectoparasites on cnnoids and ophiuroids or as endoparasites In the body cavlty of asteroids and spatangoid echinoids. Echinoderm castration by copepods and ascothoracids was reported several times in the literature. Parasitic crabs nlostly occur on or in echino~ds.Ectoparasitic crabs often exert major effects and may kill their host; gut-inhabiting species may produce conspicuous host deformation. Some species of carapid fishes are known to live either temporarily or permanently in the body cavity of holothuroids and asteroids Carapid infestations do not seem to seriously affect the echlnoderms except for species permanently inhabihng the host's coelom. Parasitic associations between echinoderms and polychaetes, tardigrads, barnacles, amphipods, tanaidaceans, acarians, pycnogonids and insects have been casually reported in the literature. INTRODUCTION ous species are known to live ectocommensally on echinoderms, only 3 cases of parasitism have been The present paper is the third of a series of 4 that reported with polychaetes. -
Timing of Fission in the Starfish Allostichaster Capensis (Echinodermata:Asteroidea) in Laboratory
Timing of fission in the starfish Allostichaster capensis (Echinodermata:Asteroidea) in laboratory Tamara Rubilar1, Catalina Pastor1 & Enriqueta Díaz de Vivar2 1 Centro Nacional Patagónico, CONICET, Puerto Madryn, Chubut, Argentina; Phone: 54-2965-451024 Fax: 54-2965- 451543; [email protected]; [email protected]. 2 Universidad Nacional de la Patagonia San Juan Bosco, Fac. de Ciencias Naturales, Puerto Madryn, Chubut, Argentina, [email protected] Received 14-VI-2004. Corrected 09-XII-2004. Accepted 17-V-2005. Abstract: Timing of fission in the fissiparous starfish Allostichaster capensis under laboratory conditions is described. A. capensis generally splits across the disc along the fission plane during the spring, and then each half regenerates the missing arms during the rest of the year. The fission process can last eight hours. The heal- ing process starts immediately after fission. A. capensis has impressive regeneration ability, including a comet, without signs of disc, regenerated two new arms. Rev. Biol. Trop. 53(Suppl. 3): 299-303. Epub 2006 Jan 30. Key words: Echinoderms, asteroids, fission, asexual reproduction. According to Lawrence and Herrera (Islas Malvinas), from the subtidal zone to 100 (2000) asexual reproduction by fission is the m depth, usually on hard bottoms (Clark and rarest way of reproduction in echinoderms. Downey 1992). About 80 of the roughly six thousands extant Timing of fission in natural environments species of echinoderms are capable of asexual is unknown for A. capensis. Studies have been reproduction by fission or arm autotomy during centered in reproductive aspects (Rubilar et al. the benthic phase (Mladenov 1996). However, 2005). However it is known that fission is a sea- some starfish reproduce asexually by fission sonal process that happens every spring, when (Emson and Wilkie 1980, Ottesen and Lucas seawater temperature starts to increase and day 1982, Achituv and Sher 1991, Mladenov and length is maximum (Rubilar et al. -
Forcipulatida and Brisingida
An index of names of recent Asteroidea - Part 4: Forcipulatida and Brisingida AILSA M. CLARK1 AND CHRISTOPHER MAH2 1 Formerly of Department of Zoology, The Natural History Museum, (London, UK). Present address: Gyllyngdune, Wivelsßeld Green, Sussex, UK. ^-Department of Invertebrate Zoology, California Academy of Sciences, Golden Gate Park, San Francisco, USA KEYWORDS: Taxonomy, geographical range, Bathymetry, Asteroidea, Echinodermata. INTRODUCTION Treatment of nearly all the Forcipulatida is by Ailsa Clark, as before, but that of the Labidiasteridae and the Brisingida is by Christopher Mah, whose timely researches have enabled him to take over this specialized order. Explanation of the procedure followed in this index was given in part 1. However, the type conventions followed are briefly repeated here: Valid names for genera and species are given in bold type when in their defini- tive position alphabetically but in italics in cross references where either genus-group names have been altered in rank or species-group names have been transferred to other genera; names in ordinary type are synonyms or otherwise invalid. Asterisks before names signify doubtful or threatened names needing further attention, while asterisks under 'Range' indicate the type localities where noted during compilation. The classification of the Forcipulatida followed here is largely that initi- ated by Downey in Clark and Downey (1992: 401). Apart from the long- established Zoroasteridae, Fisher's subfamilies Neomorphasteridae, Pedicel- lasterinae and Labidiasterinae (1928)'s were raised to the rank of families apart from the Asteriidae, with which A.M.C. had previously (1962a) merged the Coscinasteriinae for want of a character to distinguish all the genera, despite considerable divergence in general faciès. -

These are important aspects for a sustainable commercial optimization and exploitation of Acanthaster planci COT especially for health related agendas or therapeutic application. This manuscript thus seeks to outline present and future research strategy and works pertinent to Acanthaster planci COT locally and global focused on evidence-based optimised sustainable exploitation as well as refining management actions to improve the performance of control programs. Among deuterostomes, the regenerative potential is maximally expressed in echinoderms such as the Acanthaster planci COT; these animals can quickly replace most injured organs.
