Eugorgia euryale Bayer, 1952:186, fig. 1
Remarks. This work represents
the first record of this species in the SAB. This species is unbranched
and very slender (1-2 mm) in comparison to other Leptogorgia
species in the SAB. The prominent, conical calyces are biserial
along the sides of the branch, sometimes alternating, with the apertures
separated by approximately 3 mm. The colonies examined for this
work are pale orange or pale pink with dark pink calyces with yellow
apertures. A band of dark pink tissue, giving the appearance of
a pink lateral stripe, connects the calyces. The inner coenenchyme
immediately adjacent to the axis is dark pink. The coenenchyme contains
elongate (up to 0.15 mm) warty spindles, asymmetrical disk spindles,
and flat, serrate anthocodial rods that approach the length of the
longest spindles. It appears as though this species may exist unattached
as some specimens have growing tips on both ends. One fragment examined
had a very small branchlet on which the calyces were separated by
5 mm or more.
This species is abundant in the Gulf of Mexico but unreported in
the SAB prior to this work.
Atlantic distribution: South Carolina, Gulf of
Mexico (Florida), 15-91 m (Bayer, 1952; 1961; NMNH collections; SERTC
