Asthenosoma marisrubri n.sp. (Echinodermata, Echinoidea) from the Red Sea Naturalis
Weinberg, Steven; Ridder, Chantal de.
Indopacific echinoids of the genus Asthenosoma that have hitherto been described as A. varium actually belong to two distinct species that are geographically separated. Animals of the eastern population, extending from Sri Lanka to Hawaii and centered around the Indonesian Archipelago and the Philippines are A. varium Grube, 1868. The new species, A. marisrubri, is so far known only from the northern Red Sea. The two species can be clearly distinguished by the distribution and the nature of the aboral spines and by the lack of tridactylous pedicellariae with blunt massive valves in A. marisrubri n.sp.

Bionomie benthique subtidale en Baie de Douarnenez ArchiMer
Blanchet, Aline; Chevalier, Claire; Gaffet, Jean-dominique; Hamon, Dominique.
Following a preliminary mapping survey using a combination of acoustic techniques, spatial patterns of sedimentologic and biological characteristics of the Bay of Douarnenez were studied in 2001 from a series of grab samples and underwater video recording aiming at calibrate the acoustic facies of the bottom and at characterized them from a biological point of view. Results obtained from community structure analysis showed that four principal ecological groups dominate : The coarse sands community with Branchiostoma lanceolatum, Glycymeris glycymeris and Glycera lapidum, the fine to medium sand community with Nephtys cirrosa, Ophelia borealis and Gastrosaccus spinifer, the mixed muddy sand and gravel community with Amphiura filiformis, Edwardsia sp. and...

Echinodermata das praias de Salvador (Bahia, Brasil) Zoologia
Alves,Orane Falcão de Souza; Cerqueira,Walter Ramos Pinto.
This paper presents 28 species of Echinoderms collected on 5 beaches of Salvador (12º54' to 13º01' S and 38º26' to 38º33' W), Brazil, which are distributed in 19 families. Ophiuroidea represented 53,6% of the collected species, followed by Echinoidea (28,6%), Asteroidea (7,1%), Holothuroidea (7,1%), and Crinoidea (3,6%). Ophiuroidea and Echinoidea were the most frequent groups, occurring at all the studied beaches while Crinoidea occurred only on 20% of them. Most of the species are characterized as belonging to the tropical warm waters, some to the shallow coastal areas and some having a broad bathymetric distribution. The richness of species values on beaches ranged from 7 to 24, at Itapua Beach, and from 2 to 14 among different kinds of habitats, where...

EQUINODERMOS ASOCIADOS A FORMACIONES ARRECIFALES EN ZIHUATANEJO Y ACAPULCO, GUERRERO, MÉXICO Boletín de Investigaciones
Zamorano,Pablo; Leyte-Morales,Gerardo E..
El conocimiento de los equinodermos de la región de Zihuatanejo y Acapulco, Guerrero, es escaso, y el existente refiere principalmente a listados taxonómicos. Con esos antecedentes, en este trabajo, se describió y caracterizó la comunidad de equinodermos asociada a arrecifes coralinos a partir de transectos de banda de 50 m de largo por 1 m de ancho. Durante 2004 se realizaron dos muestreos prospectivos (uno en época de lluvias y otro en época de secas). En total se registraron diez especies, tres asteroideos, seis echinoideos y un holoturoideo. La diversidad promedio obtenida en los 13 sitios estudiados (1.036 bits ind-1) se considera baja al compararla con la diversidad máxima posible (3.322 bits ind-1) debido a la dominancia del erizo negro Diadema...

Inferring the developmental basis of the sea star abnormality "double ambulacral groove" (Echinodermata: Asteroidea) RChHN
HOTCHKISS,FREDERICK H C.
Very rarely a ray of a sea star is unusually wide and has two parallel ambulacral grooves that extend to a single tip. Such a ray has two terminal plates that are coalesced laterally. This abnormality is inferred to develop as a rare result of regeneration because it is recorded from a species with obligate asexual reproduction (fission and regeneration of halves; no gametes). This conclusion is supported also by an example where the abnormality affects only the distal third of a ray

Late Cretaceous ophiuroids in the Binkhorst Collection at the Museum für Naturkunde, Berlin, reassessed Naturalis
Jagt, J.W.M.; Neumann, C..
A small lot of latest Cretaceous brittlestars from the Maastrichtian type area, contained in the Binkhorst [van den Binkhorst] Collection at the Museum für Naturkunde in Berlin, is restudied and, in part, illustrated for the first time. Presumably, these thirteen specimens represent only a portion of the ophiuroid material referred to in two papers by Binkhorst van den Binkhorst, both published in 1859, because all are assignable to two species which are common only in the Nekum and Meerssen members of the type Maastrichtian, namely Felderophiura vanderhami Jagt, 1991, and Ophiomusium lux Jagt & Kutscher in Jagt, 2000. Brittlestar material from lower levels within the Maastricht Formation (i.e., Valkenburg, Gronsveld, Schiepersberg and Emael members)...

Late Cretaceous-Early Palaeogene echinoderms and the K/T boundary in the southeast Netherlands and northeast Belgium — Part 4: Echinoids Naturalis
Jagt, J.W.M..
All Campanian, Maastrichtian and Danian echinoids known to date from the extended type area of the Maastrichtian Stage are listed and, with a few exceptions, also illustrated. The geographic and stratigraphic distribution of these echinoderms are documented. A total of 55 (sub)genera and 119 (sub)species (inclusive of formae), two of which are new, are recognised. A number of taxa are reassigned, while others have to remain in open nomenclature for the time being. Recorded for the first time from the area are representatives of Hagenowia and Zeuglopleurus, as well as juvenile specimens of Hemipneustes striatoradiatus. Cidaris gigas (= Temnocidaris (Stereocidaris) gigas) is accepted as a valid species. The name Cyphosoma rutoti is shown to be based on the...

Late Cretaceous-Early Palaeogene echinoderms and the K/T boundary in the southeast Netherlands and northeast Belgium — Part 6: Conclusions Naturalis
Jagt, J.W.M..
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 disintegrate into jumbles of dissociated ossicles. Bioturbation, scavenging, and current winnowing all contribute to blurring the picture still further. However, data on extant forms do allow a preliminary subdivision of fossil species into various ecological groups, which are...

Massin, C..
During a survey at the Spermonde Archipelago (22.viii-5.x.1994) 56 holothurian species were collected; ten are new to the fauna of Indonesia and one is new to science: Stichopus quadrifasciatus spec. nov. Most of the species are described, figured and discussed. As far as possible, all literature records from 1970 onwards are listed and a distribution map is given for each species.

Reproductive biology of Echinometra lucunter (Echinodermata: Echinoidea) in a northeast Brazilian sandstone reef Anais da ABC (AABC)
Lima,Eduardo J.B.; Gomes,Paula B.; Souza,José R.B..
The edible sea urchin Echinometra lucunter (Linnaeus, 1758) is a very common species on the sublittoral-midlittoral in Brazilian rocky shores. The aim of this work was to describe the gametogenesis and reproductive strategy of the E. lucunter population at Muro Alto beach in the Northeast coast of Brazil from August 2004 to August 2005. A total of 240 specimens were collected on the sandstone reef flat from a tidepool during spring low tides. The overall sex ratio was1.12:1,withoutsignificanttemporalvariationexceptinOctober2004. Firsts sexual maturity ocurred in individuals from a diameter of 20.8 mm. There was not a significant difference in gonad index between females and males during the sampling period. The female's gonad index variation was associated...

Fujita, T.; Marsh, L.M..
During the Rumphius Biohistorical Expedition (4.xi-17.xii.1990) and some additional field trips to Ambon, a total of 26 species of asteroids were collected. Seven species were new to Ambon, and four species new to Indonesia. The asteroid fauna of Ambon is now represented by 44 species. Anthenea difficilis is transferred to the genus Gymnanthenea. Taxonomical notes are given on the collected specimens for some species.
