Plexaura homomalla
Photo take at -40 ft on a coral reef , this is a common sea rod in this area. Colonies are bushy but compressed in vertical planes. Tend to branch laterally, with only occasional dichotomous branching. Mature colonies are up to 35 cm in height. It occurs in two forms: forma homomalla is broad with end branches of 4-5 mm in diameter; forma kuekenthali is taller with terminal branches of 2.5 mm in diameter. End branches are about 10 cm long. The tissue surrounding the apertures may be completely flat or only slightly raised.
Inhabit clear water patch reefs, to 55 meters depth. In shallow waters forma homomalla is more abundant, while in deeper waters especially forma kuekenthali is found. Form Florida all the Caribbean sea to North Brazil.
