Size Range
Dark green long linear grass-like leaves 1.0 – 1.5 cm wide, 25 –150 cm long. [2]
Common in shallow intertidal areas with sandy and muddy substrata, but can extend down to 4m depth. [1]
Enhalus with long strap-like leaves form good wave breakers and extensive beds give some protection to shorelines exposed to strong waves. Such thick vegetation also provides good hiding places for small species and the young of other organisms. It is a common food for the dugong and the fruits are sold   as human food in the market at Kota Kinabalu, Sabah. Enhalus is highly productive and contribute greatly to oxygenation of the seas as well as carbon sequestration, leading to reduction in the effects of global warming. [1]
Endemic No
Found in Marine Park Yes
Found in Malaysia Yes
In Malaysia, can be found in Penang (Benting Tengah, 
Gelugor), Negeri Sembilan (Cape Rachado, Port Dickson), Melaka (Pulau Serimbun, Pulau Lalang, Pulau Besar), Johor (Sg. Pulai Estuary, Merambong Shoal, Pulau Sibu), Sabah (Pulau Gaya, Sandakan, Semporna), Labuan (Pulau Papan). [1]
Enhalus flowers only in habitats where the flowers are exposed at low tides because this species undergoes aerial surface pollination. The seed upon liberation from the fruit germinates immediately after it sinks to the muddy bottom (den Hartog 1970). Flowers were found throughout the year in Sg. Pulai estuary while the annual biomass production followed a bimodal pattern (Ethirmannasingam et al. 1996). [1]
