Halimeda
Name : Halimeda Macroalgae
Identification   {MSG_BIOLOGY_LISTE_CATEGORIES}
Main identification characters
Whitish green to dark green, this alga consists of hard, disklike, calcified segments connected by flexible joints; grows 10-20 cm tall; and spreads laterally with dense random branching to form extensive clumps or mounds with many points of attachment.

The segments are usually three lobed or rounded with three radiating ribs visible on the surface.

There are at least 25 species of Halimeda and they are very common on the reef. They are estimated to have first appeared 225 million years ago.

Interaction with other species
Halimeda spp. are very robust and not easily harmed by algae eating animals - only a few species of fish feed on them. This is due to the plant excreting toxic metabolites.
