Description
Summary:EUNICEA FUSCA DUCHASSAING & MICHELOTTI, 1860 (FIGS 1I, 2O) Eunicea fusca Duchassaing & Michelotti, 1860: 25 (holotype: Turín, Italy). Eunicea fusca: Bayer, 1961: 138. Description: Colonies usually small (<0.3 m) but up to 0.5 m in height. Asexual (vegetative) propagation from fragments commonly observed (Fig. 1I). Colony with disorganized branching but with a dichotomous trend. Slim branches between 2.5 and 3.5 mm in diameter. Polyp apertures with low calyx as an enlargement of the lower lip. Middle layer with spindle sclerites up to 2 mm in length. Axial layer sclerites spindles up to 0.2 mm in length colourless or slightly violet, sometimes with large ornamentations. Polyp armature composed of slightly curved rods between 0.05 and 0.22 mm in length. Diagnostic features: The surface layer contains clubs with smooth folds, sometimes fused, up to 0.18 mm in length (Fig. 2O, see also Fig. 8). Distribution and habitat: Widespread in the Tropical Western Atlantic. Most reef environments with intermediate wave exposition and depth. Along the Caribbean coast of Colombia E. fusca was found to be very common exhibiting extensive vegetative propagation.
