The giant Caribbean sea anemone Condylactis gigantea (Weinland, 1860) (Actiniaria, Actiniidae) is one of the most common and well-known actiniarian species that inhabits in coastal and coral reefs environments of the Western Atlantic Ocean, and is distributed from Bermuda to southeast Brazil, and along the Gulf of Mexico and the Caribbean Sea (Gonzalez-Munoz, Simoes, Sanchez-Rodriguez, Rodriguez, & Segura-Puertas, 2012).
The competition with Eurythoe complanata, an abundant amphinomid of Easter Island, may limit food availability (actiniarian) and size.
Superficial cleavage occurs in many actiniarian species including Actinia fragacea, Cribrinopsis fernaldi, Halcampa duodecimcirrata, and Actinostola spetsbergensis (Nyholm, 1949; Uchida and Yamada, 1968; Siebert and Spaulding, 1976; Riemann-Zurneck, 1976; Larkman and Carter, 1984).
