04/09/2009  --I encountered a Squirrel Tree Frog and was able to shoot some high-speed video of it as it climbed a tree. While watching the video, I noticed how the frog occasionally was able to hold on by just one front foot. Then I wondered how
the frog's foot stuck at all. I was pretty sure that it was by suction (even though the toe pads look like suction cups--see below).  I searched online and discovered that the surface of a tree-frog's toe pads is not smooth. Instead, the surface is split into
many microscopic "tiles".  These sections are each surrounded by a narrow space. Mucous is extruded from the spaces between these "tiles" or "pegs".  The mucous wets the face of each "tile", which then sticks to a surface by liquid adhesion (similar
to the way a beer glass can stick to a coaster).  The adhesion of thousands of these microscopic "beer glass bottoms" combine to form a powerful sticking force.  When the  frog moves, it has to peel its toes off the surface it is clinging to.

October 17, 2004 The image below (GREEN RIDER) shows a little green hitchhiker that landed on the argo while I was mashing more rice Sunday.

                                                   GREEN RIDER
Actually, I see these Green Tree Frogs fairly often while in the rice, and usually that just land on the argo, or me, and then just jump off. This one, however, stayed for a while, and so I grabbed my "smaller" camera and took some pictures. They came out really well, I thought, so here they are.  I can't believe they came out like this!
I was got this great closeup (see REALLY CLOSE, below), and while I had the camera near it, the frog turned and faced the camera (see GET MY BETTER SIDE, below).  Finally this frog jumped off.

                     REALLY CLOSE                                                   GET MY BETTER SIDE                                            YOU WANT ME TO JUMP!?                                       WHAT ARE YOU POINTING AT?                          DON'T MAKE ME GO
Later in the afternoon, I was at it again with the argo, and another frog jumped on. This time, I reached for it (with the camera in the other hand), and the frog jumped onto my hand. It crawled to the knuckle of my curled finger, and posed for a while (see YOU WANT ME TO JUMP. above). After I took a few pictures, I gently tried to let it jump off, but it wouldn't go. I extended my finger (see WHAT ARE YOU POINTING AT, above), and the frog just crawled around on my hand and finger.  It perched on my knuckle again, where I got this great picture (see DON'T MAKE ME GO, above).  It always affects me to have such a small creature trust me like this. I want to stand still for a while and let it remain. But, I had my work to do, and I figured the frog would be safer back in the grass, so I finally got it to jump to a strand. With a slight twinge, I moved away from my brief acquaintance.
