Dari perairan Takofi Maluku Utara telah berhasil dikumpulkan sekitar 22 jenis fauna Ekhinodermata yang mewakili 6 jenis Holothuroidea, 4 jenis Asteroidea, 5 jenis Echinoidea dan 7 jenis Ophiuroidea. Kelompok bintang mengular atau Ophiuroidea merupakan kelompok yang paling menonjol untuk daerah lamun. Dari analisa kuantitatif diperoleh nilai indek diversitas tertinggi ditemukan pada stasiun II (H1 = 1,19), nilai indek kemerataan teringgi terdapat pada stasiun III (J = 0,99) dan nilai indek kekayaan jenis tertinggi didapatkan pada stasiun I (D = 1,22).
Echinoderm Biodiversity in the Takofi Coastal Waters, Moti Island, North Maluku. A total of 22 echinoderm species were found in Takofi waters, North Maluku. They were represented by 6 species of holothuroidea, 4 species of asteroidea, 5 species of echinoidea and 7 species of ophiuroidea. The Ophiuroidea were relatively common in seagrass area. The quantitative analysis on the abundance data revealed the highest diversity index of faunal assemblage at station II (H'=1.19). The highest evenness index was exhibited by the echinoderms from station III (J = 0.99), while the highest species richness was represented by them from station I (D = 1.22). |
