animal aromatic sources in perfume (from wikipedia):

Ambergris: Lumps of oxidized fatty compounds, whose precursors were secreted and expelled by the Sperm Whale. Ambergris is commonly referred to as "amber" in perfumery and should not be confused with yellow amber, which is used in jewelry.
Castoreum: Obtained from the odorous sacs of the North American beaver.
Civet: Also called Civet Musk, this is obtained from the odorous sacs of the civets, animals in the family Viverridae, related to the Mongoose.
Honeycomb: Distilled from the honeycomb of the Honeybee.
Musk: Originally derived from the musk sacs from the Asian musk deer, it has now been replaced by the use of synthetic musks.
