Inner ear bones of whales mounted on custom made black granite base.

Whales have highly evolved underwater hearing capability.
This whale ear bone known as the tympanic bulla, protects the moving parts of the inner ear. The thick rounded section known as the involcurum amplifies vibrations received by the ear complex
It is part of a specialized complex system That enables whales to distinctly detect Nuances in sound from which side the sound is coming from.
It is very difficult for humans to identify the direction of underwater sound because we cannot isolate our hearing from one side to another in a aqueous environment.
