==Description== Dactylotrochus cervicornis is a sturdy solitary coral with a short pedicel measuring 15 millimeters (0.6 in) in diameter and an encrusting base. The maximum size is in diameter and high. The fossa (central depression) is elongated and the calyx is deep. As the coral grows, certain parts of the corallite wall and septa develop more than others and two or more petal-like lobes grow, often recurving. The septa are very numerous; they are narrow except near the corallite wall and there is no central columella.
