Seagrass and Seaweed Ecosystems Seagrass • Seagrasses occur in the shallow subtidal regions of sheltered localities of the sea, gulf, bays, backwaters and lagoon. • Grow in mud flats and sandy regions. • They are submerged monocotyledonous plants adapted to marine environment for completion of their life cycle under water. • They occur along the east and west coast of Indian peninsula and Andaman and Nicobar Islands. • Occur along 5-15m depth in Indian coast • However, they can grow at more than 32 meters depth. In clear water condition, they even grow at the depth of 65 meters Seagrass meadow, Andaman Dugong dugon
Diversity of seagrass • Global composition ranges from 0.1 to 0.2% of the aquatic flora • 60 species described from world oceans • 14 species reported from India (Cymodacea rotundata, Cymodocea serrulata, Enhalus acoroides, Halodule pinifolia, H. uninervis, H. whitii, H. beccarii, H. decipiens, H. ovalis, H. ovata, H. stipulacea, Syringodium isoetifolium and Thalassia hermprichi) • Gulf of Mannar – 13 species • Andaman and Nicobar Islands – 9 species
