The Pavona Coral is a small polyp stony (SPS) coral, and is referred to as the Cactus, Potato Chip, or Lettuce Coral. Its common name “cactus,” comes from its appearance which resembles that of a cactus. These corals form thin plates as branches that are covered with polyps giving it a fuzzy appearance. Its color varies from shades of light and dark brown to green with cream or white margins. They have a fluorescent glow that can be seen beneath the polyps, giving these corals an interesting look.
