TAXONOMY
Kingdom: Animalia
Phylum: Cnidaria
Class: Anthozoa
Subclass: Hexacorallia
Order: Actiniaria
Family: Actiniidae

Genus/species; Condylactis sp.

GENERAL CHARACTERISTICS: Disc size: 10–40 cm (4-16 in) Colors differ.

 

DISTRIBUTION/HABITAT: Found throughout the Caribbean and Western Atlantic; also Indo-Pacific. Found in lagoons or on inner reefs.

DIET IN THE WILD: Like many other cnidarians, these anemones host zooxanthellae. They also collect small invertebrates and fishes with their tentacles.

REPRODUCTION: Male and female release eggs and sperm into the water. After fertilization and development, larvae metamorphose and settle out as juvenile anemones. Can also reproduce asexually through splitting and budding.

REMARKS: Indo-Pacific Condylactis spp. and clownfish do not display symbiotic behavior in the wild. However, aquarists report that if introduced in an aquarium, the anemone may serve as a clownfish host. There are no clownfish species in the Caribbean

BEWARE:
Annals of Internal Medicine: A healthy 28 year old man died of liver failure after being touched by a condylactis anemone.

Other actiniarian to be wary of are the Mimic Anemone (Phyllodiscus semoni) is known to have caused acute renal failure and severe dermatitis. The Hellsfire Anemone (Actinodendron plumosum), the Snake Anemone (Actinostephanus haeckeli), and the Armed Anemone (Dofleinia armata) are reported to cause extremely painful stings and persistent ulceration of the skin. And the Carpet Anemone (Stichodactyla haddoni) has been implicated in causing prolonged neurological damage and even anaphylactic shock in aquarists
