Green feather alga
Caulerpa sertularioides
(Gmelin) Howe, 1905

Description:
Flat, featherlike erect branches, which may reach a height of 15-20 cm. The upright branches are dark to olive green in appearance and arise from coarse, moderately thick, branching stolons. The branchlets are cylindrical ending in sharp points and opposite, giving the plant a feathery look.
Rhizoids are produced at the tips of long, descending, sometimes forked branches of the stolons, which penetrate the sand and thus anchoring the plants firmly.
The plants are coenocytic, i.e., the plant is multinucleate and nonseptate.

Habitat:
Grow in shallow sandy areas, often between protected shallow reefs. Also grow in areas of mangroves and occasionally attach to their roots.

Distribution:
From Florida into the tropics.
