 or a strip above a line of columns.


The taenia (you can only see it as a shadow) is between the groups of little triangular thingies. 

So now: tell me what a taeniacide does, if you're so clever.

Word To Use Today: taenia. This word comes from Latin from the Greek tainia, a narrow strip, related to teinein, to stretch.

And a taeniacide?

It kills tapeworms.
