Sinularia Finger Coral Beauty, Isole Raja Ampat, Indonesia - Foto stock

A perfect Finger Leather Coral Sinularia sp. dominates the underwater scenery. Sinularia has small polyps on the surface of its branches and can actually create a solid base around the bottom of the coral. Alcyonacean octocorals in tropical reefs are usually not considered as reef builders, Sinularia is actually the only reef building soft coral. Leather corals are a photosynthetic coral and will get most of their energy requirements from photosynthesis. All leather corals are poor at feeding directly but leather corals instead prefer to extract nutrients from the water column. It's a rainy late afternoon, so the water surface looks a bit strange.
