General Biology Additional Information	The stated growth rate refers to vegetative growth recorded in perennial populations whereas annual populations may expand at 30m / year in good conditions (Holt et al. 1997). The following species have been recorded only from seagrass leaves: the hydroid Laomedea angulata; the algae Rhodophysema georgii, Halothrix lumbricalis,Leblondiella densa, Myrionema magnusii, Cladosiphon zosterae, Punctaria crispata; and Cladosiphon contortus, which is larger and found primarily on Zosterasp. rhizomes.
