Abstrak :
Dari perairan Tanjung Merah Sulawesi Utara telah berhasil dikumpulkan sekitar 21 jenis fauna Ekhinodermata yang mewakili 5 jenis Holothuroidea, 5 jenis Asteroidea, 4 jenis Echinoidea dan 7 jenis Ophiuroidea. Kelompok bintang mengular atau Ophiuroidea merupakan kelompok yang paling menonjol untuk daerah lamun. Berdasarkan hasil transek yang dilakukan di ketiga lokasi yang diamati ternyata kelompok bintang mengular (Ophiuroidea) menempati tingkat kekayaan jenis relatif tinggi. Secara umum baik dalam jumlah jenis ataupun dalam jumlah individu, fauna ekhinodermata di perairan Tanjung Merah Sulawesi Utara. Komposisi jenis, struktur komunitas, zonasi dan sebaran lokal akan didiskusikan dalam tulisan ini.

Notes on the Echinoderm Fauna of the Tanjung Merah Bay Waters Sulawesi Utara. A total of 21 species of echinoderms, belonging to of 5 species holothuroidea, 5 species of asteroidea, 4 species echinoidea and 7 species ophiuroidea have been found in the Tanjung Merah of Sulawesi Utara. The Ophiuroidea were relatively common in the sea grass zone. On the basis of population density, Ophiuroidea was the dominant group and relatively highest in the individual density. The species composition, community structure, zonation, and spatial distribution of echinoderm fauna are discussed in this paper.

ABSTRACT
Indonesia is particularly rich in Echinoderms and North Sulawesi lies at the geographic centre of this biodiverse marine realm. While further studies on Sulawesi Echinodermata are required in order to obtain full understanding of current biodiversity status, preliminary SCUBA and intertidal surveys in early 2012 in the vicinity of the Lembeh Island, a region little explored previously, recorded a total of 76 species of 4 classes (Asteroidea, Ophiuroidea, Echinoidea and Holothuroidea) from shallow waters (0-40 m) at 36 sites (sea grass, coral rubble and reef). The class Crinoidea is not reported here. A review of Echinoderm literature for North Sulawesi noted that there are 114 species belonging to 5 classes of Echinodermata.
