O_o Never heard of them. Do explain?

They are little, short worms. this big: ee. if that. if you cut them in half, they live on as 2 planaria. cut the head open, they still live on.

They can't survive a hearty mincing however...

Yeah, a quarter of the head or something is required for it to live...

One can cut them into thirds and the three pieces will turn into new planaria--so two of the pieces have no head parts. I believe it is more that they need a large enough segment of every system, but it has been awhile since I have dealt with them.

Ohh~! I've never touched a Planaria! But it almost seems that each time you cut it, and wait awhile, the body will regenerate totally on both of the cut of parts of the body o-0! HOW AWESOME! O:

I saw Daphnia, Red-Blood Cells, and Amoeba, a Hydra (COOLEST MICROBE EVER!!!), a Planaria, some Vinegar Eels, and some other cool creatures under the microscope last year.

Wow! I never got to see that many under the microscope in biology last year...

Figures! Education isn't as good or interesting where I live, I mean, heck! I think my school spent too much on designing it after a prison! That's what it looks like anyway... :(

We did worms and frogs. :( I couldn't do the frog cause it reminded me of my pet frogs that died. :(
