Subclass OCTOCORALLIA (=ALCYONARIA)
Order GORGONACEA
Suborder Scleraxonia

Octocorals with a medulla composed of free or inseparably fused sclerites.

Family Anthothelidae

This family contains those octocorals with a spiculated medulla and a ring of longitudinal boundary canals separating the medulla from cortex. The family and suborder are represented by three species Iciligorgia schrammi, Diodogorgia nodulifera and Titanideum frauenfeldiiin the SAB. Titanideum frauenfeldii is the most common of the three. There are only two records of D. nodulifera in the SAB, and the present work is the first record of Iciligorgia schrammi occurring north of Florida.
