Ambergris is passed like fecal matter. It is speculated that an ambergris mass too large to be passed through the intestines is expelled via the mouth, but this remains under debate. Ambergris takes years to form. Christopher Kemp, the author of Floating Gold: A Natural (and Unnatural) History of Ambergris, says that it is only produced by sperm whales, and only by an estimated one percent of them. Ambergris is rare; once expelled by a whale, it often floats for years before making landfall. The slim chances of finding ambergris and the legal ambiguity involved led perfume makers away from ambergris, and led chemists on a quest to find viable alternatives.
Ambergris is found primarily in the Atlantic Ocean and on the coasts of South Africa, Brazil, Madagascar, the East Indies, The Maldives, China, Japan, India, Australia, New Zealand, and the Molucca Islands. Most commercially collected ambergris comes from the Bahamas in the Atlantic, particularly New Providence. In 2021, fishermen found a 127 kg (280-pound) piece of ambergris off the coast of Yemen, valued at US$1.5 million. Fossilised ambergris from 1.75 million years ago has also been found.
From the 18th to the mid-19th century, the whaling industry prospered. By some reports, nearly 50,000 whales, including sperm whales, were killed each year. Throughout the 1800s, "millions of whales were killed for their oil, whalebone, and ambergris" to fuel profits, and they soon became endangered as a species as a result. Due to studies showing that the whale populations were being threatened, the International Whaling Commission instituted a moratorium on commercial whaling in 1982. Although ambergris is not harvested from whales, many countries also ban the trade of ambergris as part of the more general ban on the hunting and exploitation of whales. It is illegal to possess Ambergris in some countries including India under the wild life protection act,1972.
Musk is a class of aromatic substances commonly used as base notes in perfumery. They include glandular secretions from animals such as the musk deer, numerous plants emitting similar fragrances, and artificial substances with similar odors. Musk was a name originally given to a substance with a strong odour obtained from a gland of the musk deer. The substance has been used as a popular perfume fixative since ancient times and is one of the most expensive animal products in the world.

Castoreum is a yellowish exudate from the castor sacs of mature beavers. Beavers use castoreum in combination with urine to scent mark their territory. Both beaver sexes have a pair of castor sacs and a pair of anal glands, located in two cavities under the skin between the pelvis and the base of the tail.
In perfumery, the term castoreum refers to the resinoid extract resulting from the dried and alcohol tinctured beaver castor. It is also used as a food additive.
Hyraceum is the petrified and rock-like excrement composed of both urine and feces excreted by the
Cape hyrax or rock hyrax. The rock hyrax defecates in the same location over generations, which may be sheltered in caves. These locations form middens that are composed of hyraceum and hyrax pellets, which can be petrified and preserved for over 50,000 years. It is also a sought-after material that has been used in both traditional South African medicine and perfumery.
