Enhalus acoroides (L.f.) Royle is the largest, long-lived dioecious
tropical species of seagrass. It is widely distributed
along the coasts of North Australia, Southeast Asia, the Western Pacific, South India and Eastern Africa (Green and Short 2003). Enhalus acoroides is highly productive (Estacion and Fortes 1988). The leaves, 0.5–1.0 m long, provide substratum for epiphytes (Brouns and Heijs 1986).
They also reduce wave motion increasing sedimentation in meadows(Komatsu et al. 2004) and consequently benefiting organisms such as the large shell Pinna bicolor Gmelin, which is common
in the beds (Matsumasa and Aioi 1999).
