Condylactis gigantea, the giant Caribbean anemone (family Actiniidae), is one of the largest and most conspicuous sea anemones in the tropical Atlantic, with thick, columnar body and long pastel-tipped tentacles spanning over 30 cm that provide shelter for commensal shrimp and fish species. The species harbors Symbiodiniaceae photosymbionts and is important in the ornamental marine aquarium trade. Genomic data have been generated for this species and are available in public databases, enabling comparative studies of cnidarian evolution and ecology.
