Lobe coral (Porites lobata) is the most common coral in Hawaii. This coral is the largest reef building species and is very different from other corals. It has branches from large lobes that are never thin or finger-like. Lobe colonies may be huge and can cover several meters or more. It has an olive-green, brown, yellowish-light green, or blue-gray color. Its calyx sides are membrane-like and elevated into sharp walls. Lobe coral is found in wave exposed areas, 0-50 meters from shore. Hawaiians call lobe coral puna.
