Biology azooxanthellate [details]Comparison Differs from Sphenotrochus in having a papillose columella, P1-2, and alternating costae. [details]
Depth range 82-645 m [details]
Diagnosis Corallum asexually reproduces by transverse division, the anthocyathus cuneiform in shape, often with downward projecting costal spurs (“fishtails”); GCD up to 6.6 mm; theca imperforate; costae independent, smooth (porcellaneous) and flat, alternating in position with septa; septa hexamerally arranged in 3 cycles; 1 crown of 10 or 12 pali; columella linear-papillose. [details]
Fossil range Early Oligocene to Recent [details]
Remark This genus and family was monographed by Cairns (1997), which included a phylogenetic analysis based on morphology. Four species, two of them known as fossils (see Cairns, 2004). [details]
Status originally described as a subgenus of Sphenotrochus, but elevated to genus level by Vaughan and Wells (1943) [details]
