Cauliflower coral (Pocillopora meandrina) is found in shallow areas where there are strong currents or strong wave action. It was the first to colonize new lava flows and is considered one of the most important pioneering corals. It is found alone near or on top of massive lava boulders or rock walls. Cauliflower coral is 16 inches (40 cm) or larger in diameter. It is a habitat for varieties of crabs and fishes. Arc-eye hawkfish are regularly seen resting on top of this coral. This species is found anywhere in the Indo-Pacific. Hawaiians call it ko'a.
