scientific name

Sphenopus Steenstrup, 1856
status

 

Sphenopus Steenstrup, 1856 

Sphenopus  Steenstrup, 1856: 37.

Type species.

Sabella marsupialis  Gmelin, 1791, by monotypy.

Gender.

Masculine.

Diagnosis.

Unitary (=solitary, non-colonial) brachycnemic zoantharians with sand/detritus incrustation in the ectoderm and mesoglea.

Remarks.

Distinct, large unitary polyps found embedded in sandy habitats with the oral disc clear of, and not attached to substrate ( Soong et al. 1999, Reimer et al. 2012b, 2015b). Recent molecular work has also indicated that this this genus-group may form a clade with some Palythoa  spp. ( Reimer et al. 2012b, Fujii and Reimer 2016).
