Cymodocea

Res Sea coastal strip (Quseir).

Egypt to Mozambique, Madagascar to west Pacific ocean.

Tidal pools, muddy coral sand.

Perennial.

Seagrass proliferates shallow to subtidal coastal waters by means of clonal growth or rhizome elongation. Some growth studies for Cymodocea serrulata were conducted in Silaqui and Pislatan Island, The Philippines (Vermaat et al. 1995), and in Seribu Islands, Indonesia at Pari Island (Kawaroe et al. 2011) and Panggang Island (unpublished data) as well as in Kerasak Cape in Bangka Island (unpublished data). Being a delicate seagrass species, it is easier to study rhizome growth of Cymodocea compare to Thalassia and Enhalus. Cymodocea serrulata growth in Seribu Islands featured slower growth performance during alternate season (June-July) compare to rainy season (February-April). Growth of rhizome length during rainy season was 1.08 mm/day (Kawaroe et al. 2011), while during alternate season was 0,24 mm/day (unpublished data). Rhizome length grows at 0.15-0.32 mm/day in Kerasak Cape as observed in April 2011 (unpublished data). Vermaat et al. (1995) observed faster rhizome growth in Philippine with 2.15 mm/day.
