White Encrusting Zoanthid GALLERYPalythoa caribaeorum
Zoanthids are similar to sea anemones, but are much smaller, grow in colonies. They only have two rings of short tentacles around their oral openings, whereas sea anemones have three or more. Large colonies of White Encrusting will inhabit shallow or deeper areas where they grow over hard substrates. They are white to creamy-yellow and shades of brown in color. Their oral cavities close when not feeding or if disturbed.
