Abstract Types of Star Fish and Sea Urchins (Asteroidea, Echinoidea: Echinodermata) In Cilik Island, Karimunjawa WatersEchinoderms are fundamentally good indicators of health and status of coralline communities in marine waters. Substrat of sandy, rububle and coral reefs are good habitat for Asteroidea dan Echinoidea. This study aim to identify sea star (Asteroidea) and sea urchin (Echinoidea) species from Pulau Cilik waters of Karimunjawa Islands. Asteroidea and Echinoidea observed using the line transect method used, ie subjects within the same distance between the transect and the transect square with observations of 2.5 m on the right and left of transect line line. Morphology, habitat type (substrate & depth) and total number of sea stars and sea urchins at each station were determined. The results showed that Pulau Cilik has six species of Asteroidea (Sea star), ie Linckia laevigata, L. multifora, Neoferdifla ocellata (Family Ophidiasteridae), Luidia alternate (Luidiidae Family), Culcita novaeguineae (Family Oreasteridae) and Acanthaster planci which belongs to Family Acanthasteridae. There were 4 species of Echinoidea Sea urchin) found, i.e. Diadema setosum, D. antillarum, D. savignyi and Echinothrix calamaris, which all were family members of Diadematidae Keywords: Ophidiasteridae, Luidiidae, Oreasteridae, Acanthasteridae, Diadematidae AbstrakEchinodermata pada dasarnya merupakan indikator kesehatan dan status dari terumbu karang di laut. Dasar perairan yang landai dengan substrat pasir, terumbu karang dan pecahan karang yang merupakan habitat bagi hewan jenis Asteroidea dan Echinoidea. Penelitian ini bertujuan untuk mengidentifikasi henis-jenis bitang laut dan bulu babi dari perairan Pulau Cilik, Kepulauan Karimunjawa. Pengamatan Asteroidea dan Echinoidea menggunakan metoda line transect yang dimodifikasi, yaitu mengamati subjek dalam jarak yang sama sepanjang garis transect dan kuadrat transect dengan pengamatan 2,5 m di sebelah kanan dan kiri garis line transect. Morfologi, tipe habitat (substrat & kedalaman) dan jumlah total bintang laut dan bulu babi di tiap stasiun dicatat selanjutnya sampel diidentifikasi berdasarkan ciri morfologi tersebut. Hasil penelitian menunjukkan bahwa di perairan Pulau Cilik ditemukan enam spesies Asteroidea (Bintang Laut), yaitu Linckia laevigata, L. multifora, Neoferdifla ocellata (Famili Ophidiasteridae), Luidia alternate (Famili Luidiidae), Culcita novaeguineae (Famili Oreasteridae) dan Acanthaster planci yang termasuk dalam Famili Acanthasteridae. Species Echinoidea (Bulu Babi) ditemukan 4 spesies Diadema setosum, D. antillarum, D. savignyi dan Echinothrix calamaris semua anggota famili Diadematidae.Kata kunci : Ophidiasteridae, Luidiidae, Oreasteridae, Acanthasteridae, Diadematidae

Abstract:
Sea stars often known as starfish are marine invertebrates that belong to Kingdom Animalia, Phylum Echinodermata, and Class Asteroidea. Sea stars are important in marine ecology and are regarded as keystone species. In Mindanao, there are 2,357 species belonging to the family Astropectinidae, Ophidiasteridae, Oreasteridae, and Acanthasteridae that are already documented. The purpose of this study is to identify sea star species present in certain unexplored places in the region such as Passig Islet, Barangay Bato, Sta. Cruz, Davao del Sur, Philippines and produce an infographic (e.g., Poster). Actual specimen collection of Asteroidea species followed the procedure stated in Scott et al. (1994) Visual Encounter Survey (VES). Then, a photograph of the collected specimens was submitted to the Bureau of Fisheries and Aquatic Resources, Region XI (BFAR) for identification and verification. Results revealed that there are three (3) families of Sea Stars in Passig Islet namely; Archasteridae, Oreasteridae and Ophidiasteridae. In terms of species, there is only one (1) species – Archaster typicus under family Archasteridae, three (3) species namely: Pentaster obtusatus, Protoreaster nodosus, and Culcita novaeguineae under family Oreasteridae and lastly, one (1) species –Linckia laevigata under family Ophidiasteridae. As a marine protected area, policy reviews specifically, re-drafting of the existing zoning maps and activity guidelines that involve biodiversity conservation are highly recommended. Restoration efforts and assessment of marine biodiversity should not only focus on mangrove forest and sea grasses, but also include the sea stars. Lastly, the locals must be involved in strengthening environmental stewardship and tourism development in the islet.

Abstract:
41 species have been identified, belonging to 29 genera, 18 families, 10 orders and 5 classes of Echinoderms in Northeast islands, from Mong Cai (Quang Ninh) to Do Son (Hai Phong). Compared to previous publications, 15 species were first identified in the Tonkin Gulf. The diversity of species numbers shows that Oreasteridae and Holothuriidae have the highest number of species (5 species/family), similarly the genus Holothuri has the highest species number (5 species). Ha Long Bay - Cat Ba has 33 species; Co To - Thanh Lan has 24 species and Bai Tu Long has 25 species. Echinoderms live in three habitats: Sand, coral, reef. The highest number of species is living in the sandy bottom and coral reefs, 39% and the lowest number only about 10% in coral reefs and reef. Van Boi, Van Ha, Da Den, Bac Van, Hong Van have high density of Echinoderms, potentially becoming marine medicine yards.

Abstract:
Sea stars have morphological characteristics that are radially symmetrical, have 5 (five) or more arms, do not have a skeleton and move freely using tube legs. Sea stars not only function as litter cleaners in the waters, but are also utilized as food processing and handicraft materials. The study aimed to determine the diversity and abundance of sea star species in the coastal area of Pandanan Hamlet, West Sekotong, West Lombok Regency. This study used the belt transect method. All starfish found in the transect recorded the type, number, and habitat characteristics. The results found 6 species of starfish from 4 families namely Echinasteridae, Archasteridae, Ophidiasteridae, and Oreasteridae. The six species are Henricia sp., Archaster typicus, Linckia laevigata, Culcita sp., and Pentaceraster sp. The diversity index (H') has a value of 0.3 - 1.7, the uniformity index (E) is 0.5 - 0.9, and the dominance index (C) ranges from 0.2 - 0.8. The highest abundance in the species Linckia laevigata with a value of 571 ind/ha (station 1) and 333 ind/ha (station 1), while the lowest abundance in the species Pentaceraster sp. 33 ind/ha. All starfish were found to be associated with seagrass plants except Pentaceraster sp.

Abstract:
The new asteroid species Sclerasterias zinsmeisteri (Asteriidae), Paragonaster clarkae, Tesselaster clarki (both Goniasteridae), and the new ophiuroid species Ophiura hendleri (Ophiuridae) are described from the late Eocene La Meseta Formation at Seymour Island, Antarctic Peninsula. The arm tip of an apparently new genus of the Oreasteridae is too incomplete to assign at the generic level. Other La Meseta asteroid species have been described elsewhere. Six of seven recognized stelleroid genera and all represented families survive, and differences between new species and existing congeneric species are subtle. Thus, the La Meseta fauna was similar to living faunas in basic composition.Among La Meseta asteroids, Zoroaster aff. Z. fulgens and Ctenophoraster downeyae are known from numerous specimens; fossils of the other species are comparatively uncommon and given the uncertainties of sampling, further taxa might await discovery at Seymour Island. Although the Paxillosida is known from Jurassic rocks, fasciole-bearing, semi-infaunal genera are first known from Cretaceous deposits, and Astropecten and Astropecten-like Ctenophoraster are first recorded from Cenozoic rocks. Zoroaster and Tesselaster are only known from deep water settings today, although they are found in the La Meseta. Ophiura hendleri, the only ophiuroid recognized to date from the La Meseta, occurs singly, in small groups, and in Paleozoic-type ophiuroid-rich beds.
