Geoff:
Sorry, I didn't make myself very clear.... That is what I meant. The 
basilisk's eye is in its face whereas an insect for example is 
a "whole". I was trying to work out if the sonar (or whatever) would 
allow them to find the eye in the face - your comment about texture 
is probably what I was after.....
