what is in a sperm whale head (science illustration)

The sperm whale has a oily wax in its head the oil is found in two separate organs. One of the organs is called a case it like this huge champer, the second is the junk it is this big junk of blubber very blubbery. The air passes through the phonic lip which will create a loud sound.All of the organ in a sperm whales head is the blow hole, phonic lip, sound, case, air sack and the junk. There are 300,000 sperm whales left there range is world wide. I think in the early 1900's there was a lot of people who would hunt the male sperm whale.
