Terumbu karang memiliki fungsi, peranan dan manfaat, baik secara langsung maupun tidak langsung bagi masyarakat yang tinggal di wilayah pesisir. Secara ekologi terumbu karang bermanfaat sebagai sumber makanan, habitat, tempat berkembang biak dan tempat hidup bagi berbagai oarganisme. Penelitian ini bertujuan untuk mengetahui jenis-jenis lifeform tutupan karang, persentase terumbu karang dan parameter fisik-kimia perairan Teluk Tanah Merah Distrik Depapre. Pengambilan data selama 7 bulan dari bulan Oktober 2017 sampai April 2018. Metode pengamatan terumbu karang yang digunakan adalah observasi dan Point Intercept Transect (PIT) pada kedalaman 3 m dan 10 m. Hasil penelitian menunjukkan bahwa terdapat 5 tipe lifeform karang Acropora di perairan Teluk Tanah Merah yaitu Acropora encrusting (ACE), Acropora submassive (ACS), Acropora digitate (ACD), Acropora branching (ACB,) dan Acropora tabulate (ACT), serta 9 jenis non-Acropora yaitu Coral branching (CB), Coral massive (CM), Coral submassive (CS), Coral encrusting (CE), Coral foliose (CF), Coral mushroom (CMR), Heliopora (CHL), Tubipora (CTU), dan Millepora (CME). Rentang tutupan terumbu karang hidup berkisar antara 42,00% sampai 56,67% di kedalaman 3 m dan berkisar antara 39,33% sampai 62,67% di kedalaman 10 m.
