Habitat
Attached to rock and dead coral, or as an epiphyte on other algae; intertidal shallow.
Distribution
Tropical Western Atlantic, Atlantic Islands and Caribbean.
Natural History Notes
Two fully corticated Ceramium species, C. nitens and C. virgatum (= C. rubrum), have been reported in the Caribbean. Ceramium nitens was the name assigned to specimens with smaller diameter axes (< 5 mm) and no visible nodal banding, while C. virgatum was the name assigned to larger diameter specimens (up to 1mm) with faint nodal banding. We currently question the distinction of these two species and until further research resolves this question are treating all specimens that would fall under these two names as C. nitens.
Depth
10 m deep. 10 m de profundidad
Characteristics
Fully corticated, uniseriate axes forming dark green to red tufts or small clumps attached to the substrata by rhizoids. Main axes 5-10 cm tall and 130-430 ┬Ám in diameter. Branching dichotomous to alternate. Darkly pigmented, small round cortical cells entirely cover the central cell filament obscuring the nodal banding characteristic of many Ceramium species, however faint banding may sometimes be visible. Long, straight surface hairs may be present at joints.

LocalityCrawl Key, Bastimento Solarte channel, Swan Cay, Isla Carenero, bayside of STRI lab.
CommentsAlthough morphologically similar, can be distinguished from other species in the family Ceramiaceae by its acute apices (not pincer-like) and presence of projecting surface hairs.
