20 Things You Somehow Missed In Avatar

20. All The Animals On Pandora Have Six Limbs

The diverse and brilliantly designed creatures on Pandora are so awe-striking that you'd be forgiven for failing to notice one commonality among their biology: they've all got six limbs.

This makes Pandora's wildlife all hexapods, though scientists have pointed out that it probably wouldn't make much sense in reality for all the planet's animals to have six limbs - a characteristic typically afforded to insects instead.

Fun fact: it's widely speculated among fans that the lemur-like creature we briefly catch sight of on Pandora at the start of the film might well be the evolutionary "missing link" between the planet's animals and the Na'vi, given that its characteristics seem to split the difference between the two.
