Sense Sonnet - Pumper

Black Piranha

The black piranha, I'm now known
For the strongest bite among fish,
Pound per pound, some research has shown
By some humans who had a wish
To measure the strength of my bite,
Which is 30 times more in force
Than my weight, which is kind of light.
The guy was in my face of course,
A fiddling around with my jaw,
Impressed by its efficiency.
Humans get easily in awe,
But so annoying they can be.

The human learned this at a cost.
The finger poked at me - 'twas lost.
