Sense Sonnet - Pumper

Electric (Fact) Eel (Fiction)

I generate electric charge
In the Amazon River flow.
Not an eel, but a fish quite large,
Human misnomer - doncha know!
I use electric to stun eats,
And navigate to find my meal,
Not human - but one of the treats
Is give'em juice and make'em squeal.
Why don't I zap myself you ask?
Well, my thick skin does insulate,
While I'm doing my tasing task.
But bumps in the road can frustrate.

I cut myself upon a rock,
And I can give me quite a shock.
