Dear Bart,
The sperm whale's head makes up 25-35% of its body.  Of this percentage,
only 12% is bone, the rest is the spermaceti organ that weighs
approximately 16 tons.  This organ is make up of two parts - the case and
the junk.  The case contains up to 2.5 tons of oil known as spermaceti.

I hope this answers your question.
