Dendronephthya soft corals are among the most visually spectacular inhabitants of Komodo's current-swept reefs, forming lush, tree-like colonies in vivid shades of red, pink, orange, purple, and yellow that transform reef walls into underwater gardens of extraordinary colour. Unlike their hard coral relatives, Dendronephthya lack symbiotic zooxanthellae algae and do not photosynthesise. Instead, they are entirely dependent on current-borne plankton and organic particles for nutrition, which is why they thrive at sites with strong water movement. Each colony consists of a soft, fleshy trunk supporting numerous branches tipped with translucent polyps that extend into the current to capture passing food. In Komodo, Dendronephthya gardens are a defining feature of the southern dive sites, where nutrient-rich upwellings from the deep Indian Ocean fuel prolific growth. Cannibal Rock is particularly famous for its dense carpets of multicoloured soft corals that drape over every available surface. These corals provide essential habitat for numerous small critters including pygmy seahorses, pipefish, shrimp, and crabs, making them ecological hotspots as well as photographic showpieces.

Filter feeder that relies entirely on capturing plankton and suspended organic particles from the water column using tiny polyps. Lacks photosynthetic algae and depends on current for food delivery.

Cannibal Rock is world-famous for its dense, multicoloured soft coral gardens. Nusa Kode, Yellow Wall, and Torpedo Alley also feature spectacular soft coral coverage. These southern sites benefit from nutrient-rich upwellings.
