Only one specimen of this species was photographically documented by ROV and collected. In live the column is low and wider proximally than distally, about 12 cm in the greatest diameter and about 7 cm in height. The diameter expanded tentacular crown is estimated as 18-20 cm.
Previously the genus Sicyonis was assigned to the family Actinostolidae, but now we place it in Sicyonidae, a family established by Hertwig in 1882.
