Sense Sonnet - Pumper

 Hair Hearing

A jumping spider sees quite well,

Thanks to having several eyes,

But also has the sense to tell

Sound waves occurring that applies.

Even though this spider does not,

Like other animals, have ears.

Sensory hairs this spider's got

With same result as though it hears.

Sound wave vibrations it does feel

From as far as ten feet away,

And does signal its brain for real

Of potential danger or prey.

Thus the jumping spider can know

To or from where a jump might go.
