Abstract:
Echinodermata merupakan biota yang dapat ditemukan hampir di semua ekosistem laut. Echinodermata cukup melimpah keberadaannya di kawasan terumbu karang, hal ini karena terumbu karang berperan sebagai tempat berlindung dan mencari makan bagi Echinodermata. Dalam rantai makanan, Echinodermata memiliki peranan sebagai pemakan seston atau detritus, dan merombak sisa bahan organik. Echinodermata juga berperan sebagai bioindikator parameter kualitas perairan. Penelitian ini bertujuan untuk mengetahui kelimpahan Echinodermata yang terdapat di Pantai Krakal, Gunung Kidul, Yogyakarta dan Pantai Pailus, Jepara, Jawa Tengah. Metode yang digunakan dalam penelitian ini yaitu metode deskriptif. Pengambilan sampel pada penelitian ini menggunakan metode transek kuadran dengan ukuran 1x1m. Hasil pengamatan di Pantai Krakal ditemukan 2 kelas dari filum Echinodermata, antara lain 3 species dari Kelas Ophiuroidea yaitu Ophiocoma erinaceus, Ophiocoma scolopendrina, Ophiarachna affinis, dan 3 species dari Kelas Echinoidea yaitu Echinometra viridis, Echinometra oblonga, dan Stomopneustes variolaris. Sedangkan jenis Echinodermata yang ditemukan di Pantai Pailus ditemukan 1 Kelas Echinodermata yaitu Holothuridea yang terdiri dari 3 spesies, yaitu Holothuria atra, Holothuria scabra, dan Holothuria leucospilota. Hasil penelitian menunjukkan kelimpahan individu tertinggi penelitian di Pantai Krakal adalah Ophiocoma scolopendrina (7,05 ind/m²),sedangkan kelimpahan individu tertinggi di Pantai Pailus adalah Holothuria scabra (2,13 ind/m²). Echinodermata is a biota that can be found almost in all marine ecosystems. Echinodermata quite abundant presence in the area coral reefs, because it serves as shelter and feed for Echinodermata. In the food chain, Echinodermata has a role as a seston eater or dentrite, and remodel the rest of the organic material. Echinodermata also serves as a bioindicator of water quality parameters. This study aims to determine the abundance of Echinodermata found in Krakal Beach, Gunung Kidul, Yogyakarta and Pailus Beach, Jepara, Central Java. The method used in this research was descriptive method. Sampling in this research used quadrant transect method with size 1x1m. The results of observation on Krakal Beach found 2 classes of Echinodermata phylum, among others 3 species of Ophiuroidea namely Ophiocoma erinaceus, Ophiocoma scolopendrina, Ophiarachna affinis, and 3 species of Echinoidea is Echinometra viridis, Echinometra oblonga, and Stomopneustes variolaris. While the type of Echinodermata found in Pailus Beach found 1 Class Echinodermata is Holothuridea consisting of 3 species, namely Holothuria atra, Holothuria scabra, and Holothuria leucospilota.

Abstract:
Echinoderms are one of organisms that inhabit intertidal areas which have important ecological roles in marine ecosystems, also have high economic values. The community structure and distribution pattern of Echinoderms in the intertidal area can provide an overview of the condition of the Echinoderm community. This research aims to determine the community structure of Echinoderms in various habitat types in the intertidal areas of Lakeba Beach, Baubau Town. The community structure of Echinoderms were observed using quadratic transec method. Echinoderms found were 777 individuals consisting of 18 species from 5 classes. Echinoderms were distributed in four habitat types, i. e. sandy, sand covered with seagrass, rocky, and rock covered with algae habitats. The highest abundance of Echinoderm was Ophiocoma scolopendrina (Ophiuroidea) and the lowest were Maretia planulata, Arachnoides placenta (Echinoidea), Holothuria scabra, H. leucospilota, Stichopus horrens (Holothuroidea), and Isocrinidae (Crinoidea). The species diversity of Echinoderms was categorized as moderate (H’ = 1,42180), species evenness was moderate (E = 0,49191), and no dominant species of Echinoderm community (D = 0,36601). Echinoderm community living in the intertidal area was influenced by antropogenic factors. Echinodermata merupakan salah satu organisme yang mendiami daerah intertidal yang memiliki peran ekologis penting bagi ekosistem laut, juga memiliki nilai ekonomis yang tinggi. Struktur komunitas dan pola distribusi Echinodermata pada daerah intertidal dapat memberikan gambaran mengenai kondisi komunitas Echinodermata. Penelitian ini bertujuan untuk mengetahui struktur komunitas dan pola distribusi Echinodermata di daerah intertidal Pantai Lakeba, Kota Baubau. Struktur komunitas dan pola distribusi Echinodermata diamati menggunakan metode transek kuadrat. Echinodermata yang ditemukan berjumlah 777 individu yang terdiri atas 18 jenis dari 5 kelas. Echinodermata terdistribusi pada empat tipe habitat yaitu habitat pasir, pasir yang ditutupi lamun, batu, dan batu yang ditutupi alga.

Abstract:
Four species of dendrochirote holothurians, Roweia stephensoni John, Pseudocnella sykion Lampert, Aslia spyridophora Clark, Roweia frauenfeldi frauenfeldi Ludwig, and one aspidochirote holothurian, Neostichopus grammatus Clark, are common inhabitants of the intertidal regions of the eastern Cape rocky shores of South Africa. All five species are sympatric for most of their geographical distribution. The intertidal distributions, densities and biomasses of R. stephensoni, P. sykion and N. grammatus were examined at six sites from Port Elizabeth to East London in the eastern Cape. At all sites the three species showed similar overlapping zonations with R. stephensoni and P. sykion reaching their highest maximum mean densities and biomasses (drained wet weight) in the lower mid-shore region (401m² and 684g/m², 181m² and 269g/m², respectively at Port Elizabeth), whilst N. grammatus in the low-shore region (61m² and 72g/m², at Port Elizabeth). The highest densities and biomasses of all three species were recorded on boulder shores that had minimal sand inundation. Seasonality of reproduction of R. stephensoni, P. sykion and N. grammatus was compared at Port Elizabeth, using gonad index values, gonadal tubule diameters, egg diameters and spermatozoon content in tubules from January 1992 until August 1993. All three species are dioecious and did not deviate from a 1: 1 sex ratio. Sizes at first sexual maturity were 2.5-2.9 cm³ for R. stephensoni and P. sykion, and 3.0-3.9cm³ for N. grammatus. The gonads of R. stephensoni and P. sykion consist of a bunch of unbranched tubules of equal diameter, with males having more tubules of a smaller diameter than females. By contrast, the gonad of N. grammatus consists of two tufts of multiple branched tubules. All three species followed annual reproductive cycles, and in R. stephensoni and P. sykion gametogenesis occurred from March 1992 until August/September 1992, and maturity was maintained until the main spawning event in January 1993. By contrast, in N. grammatus gametogenesis occurred from July 1992 until September 1992, and maturity was maintained until the main spawning event in December 1992/January 1993. Unlike R. stephensoni and P. sykion the reproductive cycle of N. grammatus was more pronounced, in that the gonad regressed after spawning. Aspects of the feeding biology of R. stephensoni, P. sykion, A. spyridophora, R.ffrauenfeldi and N. grammatus were compared, using the gross buccal tentacle morphology, type and size range of ingested food particles, and gut lengths. Scanning electron microscopy revealed that the buccal tentacles of R. stephensoni, P. sykion and A. spyridophora could be classified as dendritic, branching numerous times with the tips terminating in numerous nodes covered with discs of papillate projections. The buccal tentacle structure of R. f frauenfeldi deviated from the typical dendrochirote dendritic form. The tentacles are stout with few branches which terminate in large bulbous nodes lacking discs of papillate projections. Neostichopus grammatus possesses buccal tentacles that could be classified as peltate, terminating in large nodes which also lacked discs of papillate projections. Roweia stephensoni, P. sykion and A. spyridophora are suspension-feeders, ingesting food particles mostly <53μm in size. Roweia f frauenfeldi was classed as a "heavy" suspension-feeder, ingesting food particles mostly between 250μm-1.18μm, while N. grammatus is a deposit-feeder, ingesting benthic sediments mostly between 106-500μm. The gut lengths of the dendrochirote holothurians were found to be significantly longer than that of the aspidochirote, and may be attributed to the nature of the food ingested.

This study aimed to evaluate the effect of the supply of microalgae Chaetoceros muelleri and Thalassiosira fluviatilis on growth, survival and larval development time of the sea cucumber Holothuria grisea. Holothuria grisea larvae were obtained from a spawning induced by heat shock and were cultured in incubators conical cylinder with volume of 15 L, kept in a density of 0,5 larvae/ml and constant aeration. The temperature, pH, dissolved oxygen and water salinity were measured daily and total ammonia analysis (NH3 / NH4+) and nitrite (NO2-) were done on days 05, 09 and 14 after fertilization. Four treatments were tested with five replicates each: a diet with 100% Chaetoceros muelleri; a diet with 100% Thalassiosira fluviatilis; a combined diet containing 50% Chaetoceros muelleri and 50% Thalassiosira fluviatilis (mixed diet); and control (unfed). The feed rate ranged from 20.000 the 40.000 cells/ml for different stages of development. The length of the larvae (μm) was observed on days 2, 8 and 14 after fertilization and survival (%) on days 4, 10 and 14 after fertilization. The larval development time was followed for all treatments. There was no significant difference in temperature, pH, dissolved oxygen and salinity, to the different treatments tested. The best treatments in terms of water quality were Chaetoceros muelleri and Control, with the lowest concentrations of total ammonia and nitrite. The highest concentrations of ammonia and nitrite were found in treatments where the microalgae Thalassiosira fluviatilis was present. The survival rate for all treatments decreased over larval development being quite sharp. The best treatment, when considering the larval development time and total length (μm), was Chaetoceros muelleri. Holothuria grisea completed it larval development time in 17 days after fertilization when fed Chaetoceros muelleri, having indirect development with larval stages of auricularia, doliolaria and pentacula until the arrival of the juvenile stage.
A presente pesquisa teve como objetivos avaliar o efeito da oferta das microalgas Chaetoceros muelleri e Thalassiosira fluviatilis sobre o crescimento, a sobrevivÃncia e o tempo de desenvolvimento larval do pepino do mar Holothuria grisea. As larvas de Holothuria grisea foram obtidas a partir de uma desova induzida por choque tÃrmico e foram cultivadas em incubadoras cilindro cÃnicas, com volume Ãtil de 15 L, mantidas sob uma densidade de 0,5 larvas/mL e aeraÃÃo constante. A temperatura, o pH, o oxigÃnio dissolvido e a salinidade da Ãgua foram mensurados diariamente e anÃlises de amÃnia total (NH3/NH4+) e nitrito (NO2-) foram feitas nos dias 05, 09 e 14 apÃs a fertilizaÃÃo. Foram testados quatro tratamentos com cinco repetiÃÃes cada: uma dieta com 100% de Chaetoceros muelleri; uma dieta com 100% de Thalassiosira fluviatilis; uma dieta combinada contendo 50% de Chaetoceros muelleri e 50% de Thalassiosira fluviatilis (dieta mista); e o controle (sem alimentaÃÃo). A taxa de alimentaÃÃo variou de 20.000 a 40.000 cÃlulas/mL para os diferentes estÃgios de desenvolvimento. O comprimento das larvas (μm) foi verificado nos dias 2, 8 e 14 apÃs a fertilizaÃÃo e a sobrevivÃncia (%) nos dias 4, 10 e 14 apÃs a fertilizaÃÃo. O tempo de desenvolvimento larval foi acompanhado para todos os tratamentos testados. NÃo houve diferenÃa significativa nos valores de temperatura, pH, oxigÃnio dissolvido e salinidade, para os diferentes tratamentos testados. Os melhores tratamentos em termos de qualidade da Ãgua foram Chaetoceros muelleri e Controle, apresentando as menores concentraÃÃes de amÃnia total e nitrito. Maiores concentraÃÃes de amÃnia e nitrito foram verificadas nos tratamentos em que a microlaga Thalassiosira fluviatilis estava presente. A taxa de sobrevivÃncia para todos os tratamentos testados diminuiu ao longo do desenvolvimento das larvas sendo bastante acentuada. O melhor tratamento, quando considerado o tempo de desenvolvimento larval e o comprimento total (μm), foi Chaetoceros muelleri. Holothuria grisea completou o seu tempo de desenvolvimento larval em 17 dias apÃs a fertilizaÃÃo quando alimentadas com Chaetoceros muelleri, tendo desenvolvimento indireto com fases larvais de auriculÃria, doliolÃria e pentÃcula atà a chegada da fase juvenil.

The class Holothuroidea has approximately 1400 species existent, these nearly 50 are recorded to de Brazilian coast. Studies about this class are relatively few, particularly to the North and Northeast of Brasil. In front of the lack of information on the species of holothurians to the Brazilian coast the present study aimed to identify the species of the class Holothuroidea from the Northeast of Brasil to inventory and provide detailed taxonomic information as well as data on their distribution in the region. The Invertebrate Collection Paulo Young, of the Department of Systematics and Ecology (DSE), of Federal University of Paraíba (CIPY-DSE-UFPB) was the main the main material analyzed. Were also examined the collections of the museums of the Federal University of Bahia (MZUFBA), Museu Nacional do Rio de Janeiro (MNRJ) and University of São Paulo (MZUSP). The study of specimens includes analysis of external and internal morphological characters, beyond the pattern of calcareous ossicles, these latter are fundamental for determining the specific level. 32 species were identified, belonging to 3 orders, 8 families, 19 genera and 8 subgenera. Of the species recorded Thyone crassidisca Miller & Pawson, 1981, Euthyonidiella trita (Sluiter, 1910), Protankyra ramiurna Heding, 1928 and Holothuria (Holothuria) dakarenisis represent new records to Brazilian coast. The states with the highest diversity regarding Holothuroidea fauna was, respectively, Paraíba (n = 22 spp.), Bahia (n = 21 spp.), Alagoas (n = 14 spp.) and Pernambuco (n = 10). No species were recorded for states of Maranhão e Sergipe. The fauna of infralittoral requires better sampling. Moreover, in some species taxonomic problems were observed and discussed. The study provides the first annotated list of sea cucumbers from Northeastern Brazil. Reinforces the importance of scientific collections for systematic studies and increased knowledge of biodiversity.
A classe Holothuroidea possui aproximadamente 1400 espécies viventes, das quais 50 foram registradas para a costa brasileira. Estudos sobre a classe no Brasil são relativamente escassos, principalmente para as regiões Norte e Nordeste. Diante da carência de informações sobre as espécies de holotúrias do litoral brasileiro o presente estudo objetivou identificar as espécies da classe Holothuroidea proveniente da região Nordeste do Brasil, a fim de inventariar e fornecer informações taxonômicas detalhadas bem como dados sobre sua distribuição na região. O principal acervo analisado foi o da Coleção de Invertebrados Paulo Young, do Departamento de Sistemática e Ecologia (DSE), da Universidade Federal da Paraíba (CIPY-DSE-UFPB). Além deste, Foi examinado material do Museu de Zoologia da Universidade Federal da Bahia (MZUFBA), Museu Nacional (MNRJ) e Museu de Zoologia da Universidade de São Paulo (MZUSP). O estudo dos espécimes abrange a análise de caracteres morfológicos externos e internos, bem como do padrão dos ossículos calcários, estes últimos são fundamentais para a determinação a nível específico. Foram identificadas 32 espécies pertencentes a 3 ordens, 8 famílias, 19 gêneros e 8 subgêneros. Das espécies registradas Thyone crassidisca Miller & Pawson, 1981, Euthyonidiella trita (Sluiter, 1910), Protankyra ramiurna Heding, 1928 e Holothuria (Holothuria) dakarenisis representam novos registros para a costa brasileira. Os estados que apresentaram maior diversidade em relação à fauna de Holothuroidea foram respectivamente, Paraíba (n = 22 spp.), Bahia (n = 21 spp.), Alagoas (n = 14 spp.) e Pernambuco (n = 10). Com base nos acervos analisados, Maranhão e Sergipe foram os únicos estados em que nenhuma espécie da classe foi registrada. Nota-se que a fauna do infralitoral necessita de uma melhor amostragem. O estudo fornece a primeira lista comentada dos Holothuroidea do Nordeste. Fortalece ainda a importância das coleções científicas para estudos em sistemática e ampliação do conhecimento da biodiversidade.

Abstract:
Superfamily Himerometroidea AH Clark, 1908 (Echinodermata: Crinoidea) (formerly Mariametroidea) is the second most speciose superfamily in order Comatulida. Although it includes some of the most common species on tropical western Pacific reefs, its phylogeny is poorly understood. Genus- to species-level taxa are currently distinguished by plastic morphological characters. We revised the superfamily from species- to family-levels using a combined morphological and molecular approach. A phylogeny using two nuclear and three mitochondrial markers recovered Colobometridae and Himerometridae as paraphyletic and Mariametridae and Zygometridae as polyphyletic. Within genus Himerometra (Himerometridae), sequence data and detailed morphological examinations of multiple specimens of H. magnipinna, H. martensi and H. robustipinna indicated that these three taxa are conspecific. A similar examination of specimens attributed on morphological grounds to the genera Dichrometra, Liparometra and Lamprometra (Mariametridae) revealed a lack of substantial enough sequence and morphological differences to maintain them as distinct genera. We have synonymized all three genera and redescribed four species under the senior name Dichrometra. Additional work is needed to more clearly establish characters that will diagnose clades across the superfamily. This study illustrates the importance of reevaluating classifications that incorporate ecophenotypically and ontogenetically variable characters.
