From the bank of the canal, which was flat with good traction, about 8' above this guy, the bank was steep and muddy, so I felt pretty good about my ability to get away. He did not feel the same, as soon as the shutter clicked he whipped his tail around sweeping half way up the bank - gone in the blink of an eye - impressive!
Nothing but a trail of bubbles in his wake - I only had time to jump back a step or two - no doubt he would've had me if the elevation was more to his advantage. Probably a 7 footer, I really didn't think he'd feel threatened by me. As a general rule, I don't like putting any animal in situation where it's flight or fight, not even the littlest gecko.
I continued cycling around and came across another 7' footer, getting a little sun on top of the bank - lesson learned - I switched to the 55-300 PLM and kept a good distance back...he didn't bat an eye, but he did have a rather impressive smile
