Family Virgulariidae
Virgularia presbytes
Bayer, 1955
Virgularia presbytes Bayer
1955:295, Figs. 1, 2a-e..
Remarks. Virgularia presbytes
maintains a rigid pen-like colony that has overlapping, fleshy leaves
comprised of numerous autozooids, fused at the base in a fan-like
manner. On the ventral side, the leaves connect in a slightly offset
chevron form, but do not touch dorsally, forming a very distinct
bare dorsal track with a medial groove. The leaves appear heavily
ridged. Between the leaves are small siphonozooids in multiple rows,
visible only when the larger leaves are lifted to expose the axis.
The axis is white, rigid and becomes flattened towards the base.
V. presbytes usually lacks spiculation.
Atlantic distribution: North Carolina to Florida,
Gulf of Mexico, Trinidad and Tobago, Surinam, and Brazil, 9-91 m
(Bayer 1955; Bayer 1959; Bayer 1961; NMNH collections; SERTC collection).
