Summary[edit]
DescriptionLumba-lumba Hidung Botol (Tursiops truncatus).jpg |
Bahasa Indonesia: Lumba-lumba Hidung Botol (Tursiops truncatus) memiliki kebiasaan melompat dengan berkelompok di atas permukaan laut yang menjadi pemandangan indah bila kita menyaksikannya. Jika pernah melihat, mereka seolah-olah mengejar kapal-kapal ikan sambil berkejaran dan berlompatan. Perilaku ini merupakan usaha si lumba-lumba untuk mengejar kelompok ikan atau sumber pakannya dan untuk bermigrasi ke tempat lain secara berkelompok.
Dari perilaku tersebut, nelayan memanfaatkannya sebagai indikator adanya kelompok-kelompok ikan lain di daerah tersebu. Maka dari itu, tak heran bila Lumba-lumba Hidung Botol menjadi sahabat para nelayan di perairan. Namun, sangat memprihatinkan jenis ini juga banyak dimanfaatkan sebagai hewan sirkus karena kecerdasan dan kelucuan yang dimilikinya. Ancaman utama bagi jenis ini adalah penangkapan yang tidak disengaja (bycatch), terdampar (stranded) dan perusakan habitat oleh aktivitas manusia. Berdasarkan status perlindungan dalam hukum negara Republik Indonesia, lumba-lumba Hidung Botol masuk satwa yang dilindungi oleh Undang-Undang No. 5 Tahun 1990 Tentang Konservasi Sumber Daya Alam Hayati dan Ekosistemnya dan Peraturan Pemerintah No. 7 Tahun 1999 Tentang Pengawetan Jenis Tumbuhan dan Satwa. Selain itu, berdasarkan status Perdagangan Internasional yang diatur oleh CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora), Lumba-lumba Hidung Botol masuk ke dalam Appendiks II, yaitu jenis yang statusnya belum terancam tetapi akan terancam punah apabila dieksploitasi secara berlebihan. Diperlukan kerjasama dari berbagai pihak untuk kelangsungan hidup Lumba-Lumba Hidung Botol agar tetap lestari di habitat alaminya. |
