Answer 2

It is found in Sargassum.

• It represents an algae which is brown with grapes that serve as air bladders to remain it buoyant.
• It might typically resemble the connected marine plants that may be typically seen in coastal waterways.
• Its air bladder supports the seaweed floating, allowing it to be closer to the sun. Many of these species retain a sturdy, flexible body with a rough, sticky feel that allows them to endure swirling currents.
