Tingkat Keberhasilan Penetasan Telur Penyu Hijau (Chelonia mydas) dan Penyu Sisik (Eretmochelys imbricata) Di Pulau Mangkai Kepulauan Anambas
Penyu adalah biota yang termasuk kategori hewan dilindungi, karena memiliki tingkat keterancaman punah yang tinggi dari faktor alami maupun antropogenik. Penyu menghabiskan hidupnya di laut lepas dan pergi ke daratan untuk bertelur pada setiap musimnya. Keberhasilan penetasan telur penyu menjadi hal yang penting sebagai upaya untuk menambah populasinya.
