More planarians on the sidewalk when I got to work today!!
We counted about a dozen planarians, ranging in size from baby to 8 inches. What was most intriguing was the behavior of the worms we saw on the sidewalk as well.
Here is a close-up of one of the worms we saw. It doesn’t look like a normal worm to me. It doesn’t seem to have a clitellum. Do you know what species it is?
There were about a half dozen worms that were crawling away from the grass towards the parking lot. They were moving in a very strange manner! They seemed to have a singular focus of getting the hell away from the grass. The best way I can describe their motion and behavior is to say that they were writhing. Several of them managed to pop up off the ground as they twisted and turned their little bodies.
I captured a little bit of bad video of them crawling away, but did not get the full-featured writhing on camera.
What is going on here?
