We spotted this reptile, a water monitor lizard.  It's probably about 
two meters long.  I think it was more scared of us than we were of it 
(which is surprising, as we were pretty scared of it): it ran away 
once we were within thirty feet.  (Basically, it ran as soon as we 
noticed it.) <br /> Its head is the far side.  I think I caught it 
with its long tongue sticking out!
