Is this spermaceti peculiar to the 
Sperm Whale, or to other cetaceans also have a similar secretion?  
If it has something to do with echolocation and is peculiar to the 
Sperm Whale, what do other cetaceans use for echolocation?
    Many thanks. - - John C. Funk,

The spermaceti is similar to the contents of the melons of other
odontocetes. I am not aware of any descriptions of the spermaceti that
indicate that it is any different, so other odontocetes use it for
echolocation as do sperm whales, but on the sperm whales it has evolved into
a new form, possibly with new functions, such as communication and prey
