Hydnophora
Hydnophora spp., commonly known as horn corals, belong to the family Merulinidae. They are widely distributed in the Indo-Pacific region, typically inhabiting reef slopes, lagoonal areas, and sheltered reef flats. Colonies are massive to sub-massive, sometimes forming irregular mounds, and are characterized by the presence of numerous conical or knob-like projections (tubercles) on the colony surface, giving the coral a rough and spiny appearance.
