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. -
Reproductive Biology in the Starfish Echinaster (Othilia) Guyanensis (Echinodermata: Asteroidea) in Southeastern Brazil

E-mail: [email protected] ABSTRACT. Echinaster (Othilia) guyanensis Clark, 1987 is an endangered starfish distributed throughout the Caribbean and Atlantic Ocean. Even though it has been extensively harvested, little is known about the biology and ecology of this starfish. Here, we examine reproduction seasonality in E. (O.) guyanensis. Individuals were collected monthly for one year, including four complete lunar phases. The gonad index (GI) was calculated to determine annual and monthly reproductive peaks. Gametogenesis stages were also determined. Sex ratio was 1:1.33 (M:F). Gonadosomatic index, body weight, central disc width and arm length were similar for both sexes. Gonads were present in all animals with arm length greater than 36.2 mm. Lunar phase was not associated with E. (O.) guyanensis reproduction. GI and gametogenesis patterns suggest that starfish have an annual reproductive peak with spawning during autumn months (March to May). KEY WORDS. Brazil; reproduction; gametogenesis; -

Abstract: Sphingolipids are complex lipids widespread in nature as structural components of biomembranes. Commonly, the sphingolipids of marine organisms differ from those of terres- trial animals and plants. The gangliosides are the most complex sphingolipids characteristic of vertebrates that have been found in only the Echinodermata (echinoderms) phylum of invertebrates. Sphingolipids of the representatives of the Asteroidea and Holothuroidea classes are the most studied among all echinoderms. In this review, we have summarized the data on sphingolipids of these two classes of marine invertebrates over the past two decades. Recently established structures, properties, and peculiarities of biogenesis of ceramides, cerebrosides, and gangliosides from starfishes and holothurians are discussed. The purpose of this review is to provide the most complete informa- tion on the chemical structures, structural features, and biological activities of sphingolipids of the Asteroidea and Holothuroidea classes. -

[email protected]; [email protected] 2 Museo de Ciencias Naturales Bernardino Rivadavia, Ángel Gallardo 470, Ciudad Autónoma de Buenos Aires, Argentina. [email protected]; [email protected] ABSTRACT. Asterozoans are free living, star-shaped echinoderms which are important components of benthic marine faunas worldwide. Their fossil record is, however, poor and fragmentary, probably due to dissarticulation of ossicles. In particular, fossil asteroids are infrequent in South America. A new species of starfish is reported from the early Valanginian of the Mulichinco Formation, Neuquén Basin, in the context of a shallow-water, storm-dominated shoreface environment. The specimen belongs to the Astropectinidae, and was assigned to a new species within the genus Tethyaster Sladen, T. antares sp. nov., characterized by a R:r ratio of 2.43:1, rectangular marginals wider in the interbrachial angles, infero- marginals (28 pairs along a median arc) with slightly convex profile and flat spines (one per ossicle in the interbrachials and two per ossicle in the arms). -

Growth and Reproductive Biology of the Sea Star Astropecten Aranciacus
Baeta et al. Helgol Mar Res _#####################_ DOI 10.1186/s10152-016-0453-z Helgoland Marine Research ORIGINAL ARTICLE Open Access Growth and reproductive biology of the sea star Astropecten aranciacus (Echinodermata, Asteroidea) on the continental shelf of the Catalan Sea (northwestern Mediterranean) Marc Baeta1,2*, Eve Galimany1,3 and Montserrat Ramón1,3 Abstract The growth and reproductive biology of the sea star Astropecten aranciacus was investigated on the continental shelf of the northwestern Mediterranean Sea. Sea stars were captured monthly in two bathymetric ranges (5–30 and 50–150 m) between November 2009 and October 2012. Bathymetric segregation by size in A. aranciacus was detected: small individuals inhabit shallow areas (5–30 m), while large individuals inhabit deeper areas of the conti‑ nental shelf (50–150 m). Recruitment was recorded twice nearshore but no recruitment was detected offshore during the whole study period. Three cohorts were identified in each bathymetric range and growth rates were estimated. A. aranciacus population exhibited a seasonal growth pattern, being higher from June to October in the nearshore cohorts and from February to October in the offshore ones. Histology and organ indices revealed that spawning likely started in March, coinciding with the spring phytoplankton bloom and the increase in sea water temperature, and extended until June–July. Ratio between males and females was approximately 1:1 throughout the year and in both bathymetrical ranges. The size at first maturity (R50 %) was estimated to be R 112 mm. A. aranciacus did not show an inverse relationship between gonad index and pyloric caeca index. = Keywords: Asteroidea, Starfish, Mediterranean and echinoderm Background Astropecten (Fam. -

Additions to the Echinoderm Fauna of Great Nicobar Island, Bay of Bengal
Rec. zool. Surv. India,' 103 (Part 1-2) : 59-66, 2004 ADDITIONS TO THE ECHINODERM FAUNA OF GREAT NICOBAR ISLAND, BAY OF BENGAL D. R. K. SASTRY*, S. PARAMASIVAM, K. P. MANIKANDAN, S. AJMAL KHAN AND L. KANNAN Centre for Advanced Study in Marine Biology, Annamalai University, Parangipettai-608 502, India INTRODUCTION Great Nicobar is the southernmost island of the Andaman and Nicobar Islands located in the Bay of Bengal. Sastry (1999) gave an account of 18 species of echinoderms known till then from this Island. During the recent intensive explorations one of us (SP) collected material of 33 species of asteroids, ophiuroids echinoids and holothurians. Of these, only six species namely, Dactylosaster cylindricus (Asteroidea), Ophiocoma dentata, Ophiocoma erinaceus, Ophiocoma scolopendrina, Ophiomastix annulosa (Ophiuroidea), and Echinometra mathaei (Echinoidea), have been reported earlier. The present report adds 27 species to the echinoderm fauna of the Great Nicobar Island. Thus the echinoderm fauna of the Great Nicobar Island comprises of 45 species. Clark and Rowe (1971) gave details of distribution in the Indo-West Pacific region and keys for the identification (up to genus only in case of holothurians). Details of description, distribution and keys for the holothurians reported herein can be found in James (1987a,b,c, 1995a,b). Since all the species are already known from other islands, these have been briefly listed below, with details of localities of collection. The material is deposited i~ the collections of the Centre of Advanced Study in Marine Biology, Annamalai Univffsity, Parangipettai-608 502. Though all the species are already known from Andaman ~~and Nicobar Islands, with only a few new to Nicobar group, the present report is considered :~ecessary keeping in view the requirement of faunal diversity of individual islands for de~laration and management of Protected Areas. -
<I>Archaster Typicus</I>
CORAL REEF PAPER BULLETIN OF MARINE SCIENCE, 38(2): 366-383, 1986 DISTRIBUTION AND ABUNDANCE OF THE SEA-STAR ARCH ASTER TYPICUS IN KABIRA COVE, ISHIGAKI ISLAND, OKINAWA Hiroshi Mukai, Moritaka Nishihira, Hiroshi Kamisato and Yutaka Fujimoto ABSTRACT The tropical sea-star Archaster typicus has a high population density on protected sandy flats in the Yaeyama Islands, Okinawa. Intensive studies of horizontal and vertical distribution patterns show that within small areas the young sea-stars show a random dispersal. With growth they shift their distribution pattern to a contagious one with patches of about 2 m x 2 m size. In the middle-scale spatial distribution, they change their center of distribution from deep to shallow intertidal bottoms with growth. Although factors responsible for the macro-spatial distribution remained obscure, aspects of the shore in relation to wind direction and life-size topography were thought to be important. The distribution of a single species may be perceived as a series of different scales of distribution ranging from regional to microscale. This relates to the gradation of abiotic environments. Some biological factors also affect distribution at each level of the environmental gradient. Both intraspecific and interspecific interactions influence distribution. Therefore, it is necessary to get detailed in- formation on the distribution at all levels for a total understanding of the distri- bution of a particular species. We have been studying populations of the sea-star, Archaster typicus Muller and Troschel; this species occurs in tropical and subtropical coral reef areas in the Indo-West Pacific (Clark and Rowe, 1971). According to Yamaguchi (1977), its distribution is restricted to the littoral region of continents and continental islands, and the species is absent on oceanic islands. -
Larval Behavior and Geographic Distribution of Coral Reef Asteroids in the Indo-W Est Pacific 1
Larval Behavior and Geographic Distribution of Coral Reef Asteroids in the Indo-W est Pacific 1 MASASHL YAMAGU CHl 2 Marine Laboratory , University of Guam P.O . Box EK, Agaua , Guam 96910 Abstract. - Coral reef asteroids in the Indo-West Pacific fauna! region may be divided into two groups , one widely distributed from continental areas to out amo ng the scattered ocea nic island s (wide ly distributed species) and the other found on ly along the continental land mass and proximal islands (continent al species). A majo r difference in astero id faun.al composit ions between Palau and Guam is the absence of the common continenta l species on the oceanic island of Guam. Larva l development in four spec ies, Archa.vter typicu s and Protoreaster nodosus (cont inenta l species) and Culcita 11ovaeg11i11eae and Acanthaster p/a nci (wide ly distributed species) , shows mar ked similarit ies in morphology and rate of development when reared under similar conditio ns in the laboratory at Palau. The resu lts from larval cu ltivation of these com mon aste roid spec ies at Palau, Guam and in literatures suggest that the geographic distr ibution patterns might resu lt from the modes of larva l ~wimming behavior. Posi1ive geotaxis in the continental spec ies is in contrast with the negative geotax is in the widely distributed species during most of their pelagic life spa n. Introducti on The Jndo-West Pacific possesses the most extensive marine fauna! region with a homogeneous she lf fauna of high species diversity (Ekman , 1953).
