Bladder polyps (Na'vi name: rawp) are small rounded plants that grow in clusters on the forest floor, resembling blue-tinged stones.
Seen in the first film
The larger leaves store water and salt, and are grazed on by animals and harvested by the Na'vi. They have smaller brown leaves that use animal waste as a form of nutrition. When leaves are removed, new ones grow quickly in their place.

Most other plants are unable to use manure as a direct food source, however the bladder polyp is a halophyte, and can survive in very salty soils. The salt accumulating in the larger leaves absorb water through osmosis. They grow in a wide range of locations, and there are even patches of them up and at the top of Iknimaya, the "Stairway to Heaven."
Ethnobotany[]
The bladder polyp is eaten by the Na’vi for its juicy and salty taste, which is somewhat like a pickle.
Trivia[]
- In Avatar: The Way of Water, they can be seen when Spider is playing with the young Sully children, just before Neytiri turns to say she does not like him being around. Later, Jake Sully and Neytiri are seen resting by glowing bladder polyps on their date night when they realize the RDA is returning.
- According to Avatar: Frontiers of Pandora's game files, bladder polyps are used to create Mild Herbs.
