Stichodactyla mertensii

Merten's carpet sea anemone, Stichodactyla mertensii, is regarded as the largest sea anemone with a diameter of over 1 m,[citation needed]the next largest being Heteractis magnifica which has longer tentacles. This species has an oral disc that can be described as more ovoid than circular that contours to the surrounding substrate and is attached to the substrate by adhesive verrucae, which are wart like projections.[2] Its blunt or pointed tentacles are uniformly shaped, and are only about 1–2 centimetres (0.39–0.79 in) long.[citation needed] While this species can be confused with Stichodactyla gigantea and S. haddoni, they are most easily distinguished by habitat since the former two prefer sand while S. mertensii prefers rocky or coral substrate.[2] It contains obligate symbiotic zooxanthellae, and can serve as a host anemone to 17 separate fish species, the majority of which are anemonefish, with one damselfish.

Fish associated with S. mertensii include:[3][4][5]

Recently, Amphiprion clarkii and Amphiprion sandaracinos were observed to coexist within one host anemone of Stichodactyla mertensii.[6]
