Halophila is a genus of seagrasses in the family Hydrocharitaceae, the tape-grasses.It was described as a genus in 1806. Distribution of seagrasses from 529 sites in the Philippines from 1983 to 2012. It is a small herbaceous plant that occurs in sea beds and other saltwater environments in the Indo-Pacific. Hook. Temperatures lower than 15°C severely limited productivity, and at 10°C no growth occurred, although plants did not die. Halophila ovalis has very limited capacity to disperse by sea, as indicated by the short duration of various life history stages that remain floating and alive (Table 2).

Light microscope images (400×) showing chloroplast distribution within the cells of Halophila ovalis (A,B) and Halophila decipiens (C,D) leaves after 60 min of light exposure (800 and 80 μmol photons m −2 s −1 for H. ovalis and H. decipiens, respectively). Distribution of seagrasses from 529 sites in the Philippines from 1983 to 2012. Over 99% of the seagrass was in water less than 2 m deep (relative to “datum”, an extreme low water reference mark set in 1892). This paper describes the biomass, distribution and primary production of this plant in relation to environmental factors. Halophila ovalis occupied 550–600 ha in the lower reaches of the estuary, approximately 20% of the area of the main estuarine basin.
