Sense Sonnet - Pumper

Paddlefish

Found in the mighty Mississipp,
American paddlefish, I,
Named for the snout above my lip,
Flat and long and can notify
Me by electroreceptor
When food I like is nearby, yes!
My tuned snout is also good for
Navigating, like GPS.
Fishy fisherfolk can't lure me,
Due to my filter fishing way.
But by their sneaky snaggery,
I must look out for their foul play.

Smug smugglers do smuggle my roe.
Those greedy humans - doncha know!
