How do sperm whales produce their sound waves?
I was watching a program about underwater life and they showed sperm whales hunting for squid. I was surprised to hear them clicking which I presume was them sending out bursts of sound. I know that their heads are filled with a huge amount of a special oil but I was was wondering how they actually produced the sound. Do they click their tongues? Can anybody tell me how they actually do it.

The sperm whale's head contains a structure called monkey lips, through which it blows air. This can create clicks that have a source level exceeding 230 decibels re 1 micropascal referenced to a distance of 1 metre (3.3 ft) – in other words it is by far the loudest sound made by any animal, and 10–14 dB louder than a powerful rifle sounds in air at 1 metre (3.3 ft) away.[62] It has been hypothesised that these were directed at prey in order to stun them, however experimental studies attempting to duplicate this effect have been unable to replicate the supposed injuries, and have cast doubt on this idea.

Gross.
