What is halimeda and why is it such an important plant to the reef?
Halimeda spp. are calcified green algae, commonly found on coral reefs, which produce diterpenoids that function as effective feeding deterrents against natural populations of reef fish.
How does halimeda reproduce?
Halimeda reproduces both sexually and asexually. Sexual reproduction is rarely observed because it is completed in 36 hours. The process begins with gametangia forming on the edges of the segments of the thalli. By the next day, the cells of the thallus will have been entirely converted to gametangia.
Where is halimeda found?
Halimeda is often found in abundance in areas on coral reefs where herbivorous fish exert high grazing pressure, but it is among the least preferred food items there. This is probably because of the high levels of calcification, a major physical defense against predation.
