|Behind the scenes|
As tempting as the masses of seeds appear to herbivores of all kinds, they are very difficult to reach without injury. In addition to the stationary spines, some of the spines can become projectiles that are ejected using gas that collects in specialized bladders within the trunk. The alkaloid-based venom within the spines can paralyze smaller Pandoran creatures.
This species grows very slowly and seems to have invested most of its energy into defense. With the right tools and precautions, however, its armor can be breached. The Na'vi cut off pieces of the ribs for use in constructing weapons.
Tall columnar plant with thick stems bearing heavy spines along vertical ribs. Surface of stems covered with fertile zones bearing masses of seeds.
Heavy armor of stationary and projectile spines prevents all but small animals and insects from eating the seeds.
