Some animals become linguistic symbols.

0:03.2

Worms are one of them.

0:05.0

The word worm is synonymous with insignificance.

0:09.8

I've read and heard the insult, lowly worm, many times, never aimed at myself, thankfully,

0:16.6

and it's always said with this air of redundancy.

0:20.2

I mean, think about how you would feel if someone

0:22.9

called you a worm in an aggressive context. Bad, right? And if it isn't already obvious, this is not

1:47.2

This despite the fact that no worm has ever manipulated anybody that I know of.

1:56.1

These associations that you inevitably have with the word worm, purely by virtue of being an English speaker, need to be checked at the door today if you want to get as much as possible out of this

episode. Because today, we are going to talk about the common earthworm, Lumberkis, terrestris.

I'm Mackin, this is species.
