Video of Flatworms :)


I just have to geek out here a share some science stuff with you guys. In the Zoology class I teach, I tell the students about the characteristics about the phylum we’ll be looking at plus some of the characteristics of specific classes of organisms. Then I turn the students loose to look at slides, live specimens, and later in the semester, dissections.

Last week we did Phylum Platyhelminthes. One of the classes we did was Turbellaria. These are the flatworms (also called Planarians). They are flat, bilaterally symmetrical, display cephalization (nervous tissue concentrated in the head region of the organism). You’d never guess how they eat. *giggle*

Their mouths are located about half-way down their body, not in their head region like you’d expect. And they have to shove their pharynx (think of it as their throat) out of their mouth in order to eat.

These little guys are adorable (at least I think they are) with their little cross-eyed eye spots! While my students were doing their drawings of the various organisms, I took a couple of flatworms and looked at them under the dissecting scope. I had my phone and thought I’d try to get some video of the little guys.

Here’s the result:

So what do you think?? You think they’re cute or what??

    Thanks for the biology lesson. Always enjoy your blogs and hope you post more on what you are teaching in class. In college zoology we dissected fetal pigs. Learned a lot both in botany and zoology. Now I raise living guinea pigs. Carroll

    Loved it, thanks! I love these little guys. I use them in my own pharmacology and neurobiology research… Great post!
