Bubble Coral

The Plerogyra Bubble Coral is a large polyp stony (LPS) coral and is also referred to as a Grape, or Octobubble Coral. Its genus name, Plerogyra, comes from the Latin pleres (full) and gyros (wide circle), which describes the round or oval, bubble-shaped polyps resembling a cluster of grapes when open during the day. It is an aggressive coral with long sweeper tentacles that will sting corals that are placed in close proximity to it in the reef aquarium. It can also sting the reef aquarist who tries to handle it when its sweeper tentacles are out, so precaution should be taken.
