Condylactis gigantea is a tropical species of sea anemone that is found in coral reefs, shallow ocean waters, in shore areas in the Caribbean Sea - most specifically the West Indies - and the Western Atlantic Sea, ranging from southern Florida through the Florida keys. It is also commonly known as : Giant Caribbean Sea Anemone, Giant Golden Anemone, Condylactis Anemone, Haitian anemone, Pink tipped anemone, Purple tipped anemone, and Florida Condy. This species, can be easily seen growing in lagoons, or on inner reefs as either individuals or loose groups, but never as colonies.
