Meet some rare and bizarre looking marine life, from striped frogfish to blind cave fish, nautiluses to humped head Maori Wrasse. Feel the skin of friendly starfish and walk amongst the ocean fiercest predators ragged tooth sharks, black tipped sharks, sting rays in the 270 degree underwater tunnel. Better yet, dive into the depth of the Open Ocean and flirt with the sharks and colourful marine creatures, or hop aboard a glass bottom boat and simply watch them dance underneath your feet.The Oceanis Group was established 1993.
