Clavularia frankliniana is a species of colonial soft coral in the family Clavulariidae.

It forms small colonies of polyps with eight tentacles which are up to 1 cm (0.4 in) high and are usually white.

It occurs at depths down to about 600 m (2,000 ft) and grows on rocks or other hard substrates.

[1][2] This coral contains the chemical unpalatable chimyl alcohol for defensive purposes.

[2] This is insufficient to prevent the nudibranch Tritoniella belli from feeding on it, and the nudibranch incorporates the substance into its own tissues, making it distasteful to predatory starfish such as Odontaster validus, Perknaster fuscus and Acodontaster conspicuus.
