Whale Ears

When underwater hearing sound,
The ears of a whale are made so
Inside the head both "float around,"
Each tuning in to the sound flow,
Which comes in through  the whale's jaw fat,
And is transmitted to each ear.
Each ear can then determine that
Independently what to hear.
Each ear transmits to the whole brain,
To be determined by the whale
The meaning that the sounds contain,
And then react to such detail.

Whale ears are modified to be
Successful hearers undersea.
