Tongue
Long
tongue indicates the food in which Gungan's eat. The must eat some sort
of flys, for they grab their lunch with their tongue much like a frog.
Which Brings up anouther point, It looks from the movie that Gungans eat
frog-like creatures, strange.Teeth
The teeth of Gungans are similar to a horse/human in a way. Meaning these beings could be omnivours. Though I think they probably do need these kind of teeth for doing a lot of chewing. So far I havn't been able to see any canines. This could indicate they are more of a plant eater.
Ears
This is a very big part of
the Gungan's head. They wave down to lower back. Being that Gungans spend
most of their time underwater, these ears might be used as a rutter or
actual flippers to move through the water easier. After seeing the movie
again I noticed them moving strangely while he was swimming, this could
prove what I've said.Eyes
Bright yellow and fairly large. These eyes looks like they are specially
adapted to seeing under water better then most creatures. The two bumps
on the top of each eye is a mystery to me. The range of sight looks to
be straight ahead only. I'm not quite sure if they are able to move to
the sides. I did notice in the movie that the eye could literaly move up
and down.
