Hair Hearing Poem by Ima Ryma

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.
