Stichodactylidae
Stichodactylidae is a family of sea anemones that contains the genera '' Stichodactyla'' (carpet anemones) and '' Radianthus''. These species reside exclusively within the shallow waters of the tropical Indo-Pacific area and are in the main family of sea anemones that hosts several varieties of clownfishes. Most species of sea anemones are harmless to humans, but at least some species of the genus ''Stichodactyla'' are highly venomous and their sting may cause anaphylactic shock and organ failure (notably acute liver failure). In contrast, the venom of ''Radianthus'' spp. has shown potential in the treatment of lung cancer. Discovery C. Collingwood first reported species of the genus ''Stichodactylidae'' in 1868 after taking note of the existence of gigantic sea-anemones in the China Sea, containing quasi-parasitic fish. Genera and species The following species are recognized within the family Stichodactylidae: *Genus '' Radianthus'' Kwietniewski, 1896 **'' Radianthus crispa'' ...

Stichodactyla Helianthus
''Stichodactyla helianthus'', commonly known as sun anemone, is a sea anemone of the family Stichodactylidae. ''Helianthus'' stems from the Greek words ἡλιος (meaning sun), and ἀνθος, meaning flower. ''S. helianthus'' is a large, green, sessile, carpet-like sea anemone, from the Caribbean. It lives in shallow areas with mild to strong currents. General characteristics ''Stichodactyla helianthus'' is a tropical anemone commonly known as the “Sun Anemone” and part of the order Actiniaria, which comprises the sea anemones of the class Anthozoa. Described posthumously by John Ellis in 1786, these organisms, like all Anthozoa, are documented by the absence of an operculum–a calcareous shell in a circular form. Anthozoans also possess circular mitochondrial DNA and siphonoglyphs (ciliated grooves) in the pharyngeal wall. Another predominant trait resides in the presence of the coelenteron around the centralized body cavity, which is divided by distinct septa. I ...

Radianthus Crispa
The sebae anemone (''Radianthus crispa''), also known as leathery sea anemone, long tentacle anemone, or purple tip anemone, is a species of sea anemone in the family Stichodactylidae and native to the Indo-Pacific. It was first described in 1834 by Wilhelm Hemprich and Christian Gottfried Ehrenberg as ''Actinia crispa''.

These tentacles have rounded tip and the end is often colored with a purple or blue spot. The column, external structure of an anemone visible when the animal is closed, is gray in color and dotted with sticky whitish "warts". The sea anemone, being member of the Hexacorallia, usually carries a number of tentacles multiple of six and they are positioned in concentric circles. These are light beige to purple.

Stichodactyla
''Stichodactyla'' is a genus of sea anemones, of the family Stichodactylidae. They are host anemones, which maintain a relationship mutualistic with other animals, in their case with crabs of the genus '' Mithraculus'', shrimp of the genus '' Periclimenes '', and with various species of clownfish, of the genus ''Amphiprion'', establishing a relationship of coexistence. In this way, crabs and fish protect themselves from their predators between the stinging tentacles of the anemone, and the anemone benefits from the cleaning of its oral disc and tentacles as a result of the continuous movements of the animals.
