    Hi Josiane,
    From what I have been able to find, the spermaceti appears to be unique to the sperm whale. In the paper, The face that sank the Essex: potential function of the spermaceti organ in aggression (, the authors indicate that only the sperm whale has this organ.

    I would like to know if beaked whales (ou Ziphiids) have a spermaceti organ
    in thier head like the sperm whale?
    We have here a skull of a northern bottlenose whale femele and we prepare an
    informative text on it for our interpretation centrer.
    Thanks a lot for your help,
