Halodule uninervis

Halodule uninervis, commonly known as needleleaf seagrass, is a fully marine aquatic plant that grows submerged in shallow tropical coastal waters and is not suitable for conventional home gardening. It requires stable saline or brackish water conditions, adequate sunlight penetration, and sandy or muddy substrate to thrive. This species is primarily of ecological importance as critical habitat for sea turtles, dugongs, and juvenile fish rather than a decorative plant for purchase.
