Penelitian tentang keanekaragaman biota laut di perairan Indonesia, khususnya di Teluk Ambon, Maluku, telah dimulai sejak tahun 1705 oleh G.E. Rumphius. Dalam kurun waktu setelahnya hingga tahun 2000-an ada kemungkinan terjadi perubahan kondisi lingkungan atau habitat di perairan Teluk Ambon. Oleh karena itu, kajian terkini mengenai status biota laut yang ada di perairan Teluk Ambon dan sekitarnya perlu dilakukan. Kegiatan penelitian bertujuan untuk menginventarisasi timun laut di Teluk Ambon, yang dilakukan pada bulan JuliâOktober 2009 di 12 stasiun penelitian. Metode yang digunakan adalah koleksi bebas dengan peralatan snorkeling dan selam. Hasilnya didapatkan 18 spesies timun laut, dua spesies di antaranya (Holothuria atra, Opheodesoma grisea) memiliki sebaran dan preferensi habitat yang luas karena dijumpai di empat sampai lima stasiun pengamatan. Hasil inventarisasi ini ditambah dengan hasil penelitian sebelumnya berdasarkan studi pustaka dari tahun 1990 menunjukkan bahwa jumlah spesies timun laut yang ditemukan di Teluk Ambon adalah 46 spesies, yang berarti sekitar 13% dari perkiraan jumlah spesies timun laut di Indonesia (Â±350 spesies). Fluktuasi jumlah dan komposisi spesies yang berhasil diinventarisasi dalam kurun waktu 1990 hingga penelitian ini dibahas secara detail dalam tulisan ini. Masih sangat besar kemungkinan akan didapatkan spesies catatan baru bahkan spesies baru di lokasi ini, seiring dengan semakin meningkatnya pemahaman dalam pemilihan metode inventarisasi dan kemampuan dalam mengidentifikasi spesies.

The so called âblack sea cucumberâ are found in Indonesia as several species including HolothuriaÂ atra, H. leucospilota, H. coluber, H. excellens and H. turriscelsa. The local community of Wainure village near Pombo Island in central Maluku had reported that most sea cucumbers inhabiting the island are the black sea cucumbers or locally known as âteripang hitam.â They are occasionally consumed but not exploited excessively by the locals. The goals of this study are to identify the species of black sea cucumbers inhabiting Pombo Island and map their distribution to understand the microhabitats of black sea cucumber. Two field surveys conducted in March and April 2014 collected more than 550 individuals of black sea cucumbers that belong to two speciesÂ Holothuria (Halodeima) atra Jaeger, 1833, and Holothuria (Mertensiothuria) leucospilota Brandt, 1835. Furthermore, distribution maps of these two species show that they are found only along the SE to SW coast of the island. Such distribution may relate to the availability of marine vegetation, as well as boulders and stones that provide shelters to the organism. The distribution maps also show that H. atra has a wider distribution than H. leucospilota in Pombo Island. This may be due to the semi-cryptic habit of H. Leucospilotaâs (i.e. hiding its posterior body under rocks or crevices), making its distribution restricted to areas that provide ample shelters.

THE FIRST RECORD OF Holothuria (Semperothuria) Roseomaculata KERR, 2013 (Echinodermata: Holothuroidea) IN INDONESIA Setyastuti, Ana

This paper documents the first record of Holothuria (Semperothuria) roseomaculata Kerr, 2013 (Echinodermata: Holothuroidea) from Indonesia. A freshly salted specimen was collected from fishers in Sumbawa, West Nusa Tenggara, Indonesia. This species was previously recorded from Yap and Chuuk States in the Federated States of Micronesia, Papua New Guinea, Palau, Okinawa-Japan, Sabah, Borneo-Malaysia, Solomon Islands, Vanuatu and New Caledonia. Reference material has been deposited in the Reference Collection of the Research Center for Oceanography, Indonesian Institute of Sciences in Jakarta, Indonesia.Â

The occurrence of sea cucumber, Holothuria atra, was assessed in the seagrass area of the Bama beach, Baluran National Park in East Java. The study investigated the frequency and early stages of seagrass association preference of H. atra. Survey was conducted in May 2011 using belt transect (1m x 100m with three replicates). Frequency of H. atra and their association with seagrass were recorded. Furthermore, length and wet weight of each individual of H. atra were measured. The total of 146 individuals of H. atra were observed in which 37.67% associated with Enhalus acoroides (EA), 23.29% associated with Cymodocea rotundata (CR), 23,29% associated with mixed seagrass species of E. acoroides and C. rotundata, and 15.75% associated with no seagrass habitats. The results suggested that small size H. atra might prefer to live under the taller seagrass stands such E. acoroides, which could be morphologically benefits the H. atra by providing better protection and shelter area. Keywords: Holothuria atra, Enhalus acoroides, Cymodocea rotundata, Baluran National Park
