I found this little tree frog stuck to the side of the outboard motor on our boat yesterday (the boat is on land right now). So, I snapped a quick photo or two, touched his back with my finger and went on my way. I don't know why I touched him ... for some reason I wanted to know what this particular frog felt like.
He felt clammy. Very clammy.
Anyway, after downloading the photos, I noticed the round spot behind his eye. I hadn't noticed this when I touched him, but the spot is very pronounced in the photo, so I thought I should look into it. After all, if I'm going to be touching frogs (and I don't know if this will be a regular thing or not, but just in case), I ought to know what's what.
Science has never been my strongest subject. I always liked science, but, I tended to lean (heavily!) toward other, less "science-y" subjects. In fact, I opted to take Psychology in college for my "science" credits just because I could and it was much more appealing to me at the time than biology or (gasp!) physics.
But, things, as they often do, change and I find myself more and more interested in science these days. I really, really wanted to know what the round spot behind this little tree frog's eye was....
In case you are now wondering too, it's his "Tympanum". The Tympanum is an external hearing structure located behind the eyes in frogs and toads. It transmits sound waves to the frog's inner ear. It's how he "hears".
And now you know.
Don't you feel smarter? I know I do!
