How does seaweed stop itself from drying?

Seaweed prevents desiccation through several adaptations. It has a gelatinous coating that helps retain moisture and can absorb water directly from the surrounding environment. Additionally, some species possess specialized structures, like air bladders, that keep them submerged during low tides, reducing exposure to air and preventing drying out. These adaptations enable seaweed to thrive in fluctuating tidal conditions.
