Halodule pinifolia explained

Halodule pinifolia is a seagrass species in the genus Halodule. It is found in shallow sea waters.

Distribution and habitat

This is a common seagrass in Asian tropical coasts. Halodule pinifolia forms homogenous patches in intertidal places or occasionally intermixed with other seagrasses (Skelton and South 2006). Halodule pinifolia grows in sandy or muddy sand substrates from upper littoral to subtidal areas. It is ephemeral with rapid turn-over and high seed set, and is well adapted to high levels of disturbance. This species is can grow rapidly and is a fast coloniser. Often heavily epiphytised. ^[2]
