Title: How do fish and chameleons process visual data?
Post by: royden on 22/02/2010 12:30:02

Royden asked the Naked Scientists:
   
Humans have stereo vision and the brain receives 2 pictures of the same article and uses the trig. of the triangle between the eyes and the object to assist with distance perception.

How do animals like fish and chameleons process their info when they receive two completely different objects?

The left eye sees danger; the right sees supper; what is the animal's reaction?

What do you think?

You might also wonder how our eyes track so well. Recall that the fovea is the sharp image at the center and our eyes track together very well. The image from the left side of the left eye and the left side of the right eye go to the right side of the brain and the right sides of both eyes go to the left side of the brain.

Animals with eyes on the sides of the head do not have overlapping vision. This includes mammals such as horses and cows.
