Dactylotrochus is a genus of large polyp stony corals from the Red Sea and western Pacific Ocean.

Dactylotrochus cervicornis is a sturdy solitary coral with a short pedicel measuring 15 millimeters (0.6 in) in diameter and an encrusting base.

The septa are very numerous; they are narrow except near the corallite wall and there is no central columella.

[5] D. cervicornis is known from the Red Sea and from various oceanic islands in the Indo-Pacific region; it occurs in Guam, Hawaii, Palau, Vanuatu and Wallis and Futuna, and also from the eastward slope of Bikini Atoll and the Baie de Sandal in New Caledonia.

It spreads its tentacles to catch the plankton on which it feeds and can also absorb dissolved organic matter from the water.
