Lucinaria fibriata

The binary sunshine is one of many life forms on Pandora found to have a simple nervous system. These baffling "zooplantae" continue to be a source of wonder (and some confusion) to scientists.

The binary sunshine is also unusual due to its highly advanced mechanism of bioluminescence. The leaves are modified into enclosed bulbous structures that resemble lamps when they glow. These life forms are able to detect the presence of danger by sensing the emission of volatile stress hormones from living organisms. For the Na’vi, the colors emitted by the glowing leaves signal whether the landscape is calm or danger is near. (Read more)
The binary sunshine is adapted for vegetative reproduction where parts of the organism can reproduce new clonal “planimals” without the need for flowers. When a leaf is removed or falls off of a stem it will produce adventitious roots from its base and start growing as an independent planimal. The Na’vi collect the leaves and plant them at crossroads and other key locations to use as sentinels that signal approaching threats.

There is potentially a huge market on Earth for these life forms, which could be used as natural landscape lighting that does not contribute to pollution or global warming. The potential effects on Earth's ecosystem are unknown.
