The fauna of Pandora is characterized by its almost universal aggression towards anything entering its' territory. Any intrusion near an animal's home is usually met with immediate attack. There are many forms of complex life; see for details. One common trait among the local fauna is that each species produces "elemental" variants. Some specimens breathe fire or manipulate electricity, while others can spit acid or even cause explosions. There are also a variety of plants on Pandora, although the local flora is sparse in many areas. One of the most common types are plants that resemble cacti, though many also resemble mushrooms.
