Located in between Rinca and Nusa Kode this submerged sea mount is well protected and free of strong currents. The site is known for its rich and abundant soft corals and varied invertebrate life. Some
large green and blue magnificent anemones sway in the currents on the southern side. Sea apples (Pseudocolochirus Violaceus) are also abundant, their bodies decorated in amazing maroon, studded with golden beads with bright yellow or cream tentacles that they use to filter feed on plankton. Huge red gorgonians play home to pygmy seahorses which are quite tricky to spot. Flamboyant nudibranchs, featherstars, tunicates, cleaner shrimp and
fire urchins with Coleman shrimps can all be found here.
Located just north of Cannibal Rock is this rocky patch of reef at around 15 meters is named after its topredo rays. Macro critters such as frogfish, worms and pipefish can be found living in the sandy patches and coral outcrops.
