The even-toed ungulates (Artiodactyla) have many specialized skin glands, the secretions of which are involved in semiochemical communication. [2] These glands include the sudoriferous glands (located on the forehead, between the antlers and eyes), the preorbital glands (extending from the medial canthus of each eye), the nasal glands (located inside the nostrils), the interdigital glands ...

The glands are located in large preorbital pits in the lacrimal bone, and are surrounded by specialized facial muscles that compress them to express the secretions more effectively. In contrast, the saiga antelope ( Saiga tatarica ) is a polygamous and somewhat nomadic species which does not occupy any permanent territory at any time during the ...
Above: Ozopore (circled) of the millipede Martensodesmus cattienensis.Below: ozopore magnified. An ozopore is the opening of a defensive gland present in some arthropods, notably in millipedes of the order Polydesmida [1] and in harvestmen, the eight-legged arachnids also known as "daddy long-legs".
The preputial glands of female animals are sometimes called clitoral glands. Male canids scent-mark their territories with urine and preputial gland secretions. [ 1 ] [ 6 ] The preputial glands of male musk deer produce strong-smelling deer musk which is of economic importance, as it is used in perfumes .
Castoreum. Castoreum / k æ s ˈ t ɔːr i ə m / is a yellowish exudate from the castor sacs of mature beavers used in combination with urine to scent mark their territory. [1] [2]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. [3]
Insect pheromones are produced by a variety of exocrine glands consisting primarily of modified epidermal cells at various sites on the insect body. For example, the abdominal glands of the female silkmoth release traces of the (E,E)-isomer of alcohol as well as the analogous (E,Z)-aldehyde bombycal, in addition to the sex pheromone bombycol.
Among cats, Fel d 1 is produced largely in their saliva and by the sebaceous glands located in their skin. It is the primary allergen present on cats and kittens. [1] [4] The function of the protein for cats is unknown, but it causes an IgG or IgE reaction in sensitive humans (either as an allergic or asthmatic response).
