Similar to Air Prang, Teluk Kembahu or Kembahu Bay is divided into three sections. Shortened as TK, there are TK1, TK2, and TK3. This dive site is another gentle black sandy slope and one of the best muck dive sites in Lembeh Strait.
Known as the site where the mimic octopus was first observed, there are also low coral patches and small bommies, creating comfortable shelters for giant frogfish and stargazers. Different species of wasp fish, devilfish, scorpionfish (including Ambon scorpionfish), and other species of octopus, like blue-ringed, can also be found here.
