Females have four mammae, two pectoral and two inguinal. They also have a uterus that is bicornuate, and a placenta that is chorioallantoic.
|
|
The female has three pairs of mammae which feature distinguishes this genus from other members of the Oryzomyini tribe which have four pairs.
|
|
They appear to breed at the beginning of the wet season (November to December). 2-3 young are born in burrows or rock crevices. Females have two pairs of abdominal mammae.
|
|
The short ears are brown in color. The tail nearly lacks hairs and is brown above and somewhat paler below. Like most oryzomyines, it has eight mammae, including a pectoral pair.Thomas, 1898, p.
|
|
It has five toes on each foot, which is bare from the sole to the wrist and heel. Their faces are short, and have only two molars on each jaw. Females have six mammae.
|
|
Females have two mammae on the lower abdomen for feeding young. The mass ranges from 300 to 950 g. Head and body length is 290–350 mm, and reaches 535–640 mm with tail.
|
|
The male had enlarged testes and the female had recently stopped lactating and had large mammae. Two others followed in 2003, also from the national park, and caught in woodland near rivers.Bates et al., 2006, pp.

Sciurus deppei can reproduce year round, but is usually seen around the end of the dry season. Their litter size can vary quite a bit from 2-8 young, but usually on average has around 4. Most Sciurus have 4 pairs of mammae, milk secreting organ on female mammals, but the S. deppei only has 3 functional pairs of mammae. Note that according to the generic key by de Vivo & Carmignotto in 2015, this characteristic would place this taxon in the genus Notosciurus along with the red-tailed squirrel, Andean squirrel, and likely Richmond's squirrel.
|
|
Females go into estrus up to nine times a year. Males initiate and terminate copulation without much courting. Gestation is approximately eight weeks, and each litter averages 2–4 babies, though they have six mammae. Females are capable of having three litters per year.
|
|
The tail is darker above than below in T. talamancae, but there may not be a difference in color in T. bolivaris. The tail appears naked, but is covered with fine hairs. Females have four pairs of mammae, as usual in oryzomyines.Musser et al.

The body length of the golden mouse ranges from 50 to 115 mm. The prehensile tail is from 50 to 97 mm in length, generally the same length as the mouse's body. Male golden mice have a baculum tipped with cartilage. Females have six mammae.
|
|
There are two pairs of mammae. The honey badger possesses an anal pouch which, unusual among mustelids, is eversible,For illustrations, see . a trait shared with hyenas and mongooses. The smell of the pouch is reportedly "suffocating", and may assist in calming bees when raiding beehives.

|
Upper canine teeth in males form sabers that can extend past the jaw, but not in females. Unlike most cervids, this creature possesses a gallbladder and does not have the same facial glands. Mature males have a musk gland between the navel and genitalia, and females have two mammae.
|
|
Females have eight mammae. The rostrum (front part of the skull) is long and robust and the braincase is rounded. The bony palate is relatively short. The IUCN assesses the conservation status of the species as "Data Deficient"; it is poorly known but may be threatened by habitat destruction.
|
|
It has six mammae. Two different karyotypes have been reported for this species: 2n=36, FN=68; and 2n=40, FN=76. It is a solitary, nocturnal animal, usually seen after nightfall or before dawn, feeding on grass and browse. It has also been recorded eating Harrya chromapes, a bolete mushroom.

A male areola The human areola (areola mammae, OED 2nd edition, 1989.Entry "areola" in Merriam-Webster Online Dictionary. or The plural of areola is areolas or areolae, which is pronounced /əˈriːəliː/ or /əˈriːəlaɪ/. "Areola" is the diminutive of Latin area, "open place".) is the pigmented area on the breast around the nipple.

However, females are bigger and have a uniformly dark, saddle-like coloration, while males have spotty colorations. The pelages of the young transform through a series of colors during maturation. The undersides of black-spotted cuscuses have areas of yellow and white. Females possess four mammae and modified pouches for neonates that open anteriorly.
|
|
Species of Voalavo are small, gray, mouse-like rodents, among the smallest nesomyines. They lack the distinctive tuft of long hairs on the tail that is characteristic of Eliurus. The tail is long and females have six mammae. In Voalavo, there are two glands on the chest (absent in Eliurus) that produce a sweet-smelling musk in breeding males.

Females have three pairs of lateral thoracic mammae. Captive hutias have been observed to be nocturnal and arboreal and to use nest boxes placed high off the ground. Wild P. a. aedium are reported to be active only at night, to hide during the day, to feed mainly on roots and fruits, and to live in male-female pairs.

The canine teeth measure 14–22 mm in length, while the carnassials are relatively small. The Ethiopian wolf has eight mammae, of which only six are functional. The front paws have five toes, including a dewclaw, while the hind paws have four. As is typical in the genus Canis, males are larger than females, having 20% greater body mass.
|
|
The tail has a course, tubercle-like appearance at the base and on the dorsal side, with a ridged fingertip patterning on the underside to facilitate gripping. The feet are large with five digits, only the opposable digit on each hind foot is without claws. The ears of the ground cuscus are prominent and naked. The pouch opens forward and contains four mammae.

It is likely that reproduction is similar to that of Marmosa robinsoni, which gives birth to 6 to 14 young after a gestation period of just 14 days. The tiny young, measuring only up to 12 millimeters, attach themselves to the mother's mammae where they may remain for around 30 days.O'Connell, M.A. (1983) Marmosa robinsoni. Mammalian Species, 203: 1 - 6.

The soft and thick fur of these mice is darker on the back while the front fur is paler, often nearly white with a moderate orange yellow wash. The hind feet are moderately long and narrow, have six plantar pads, and have digits 2–4 notably longer than digit 5 and the hallux. All species have two pairs of inguinal mammae.

The southern multimammate mouse or southern African mastomys (Mastomys coucha) is a species of rodent in the family Muridae which is endemic to southern Africa (Angola, Botswana, Lesotho, Mozambique, Namibia, South Africa, and Zimbabwe). It is called a multimammate mouse because it can have 8 to 12 pairs of mammae (milk producing glands), in comparison other mouse species only have 5 pairs.
|
|
The large ears, about 40 mm in length, are directed nearly horizontally and are connected across the forehead by a low band of skin. Five female specimens revealed two pairs of pectoral mammae, a unique condition in mammals. It is not known if both pairs are functional. The coloration above is pale sandy to dark brown; the underparts are usually whitish.

Skeleton of pale-throated sloth The sloth has nine cervical vertebrae, giving it extreme flexibility. As a result, a pale-throated sloth can bend its head backwards and forwards through 270° and rotate it through 330°. It possesses a pair of foramina in the anterodorsal nasopharynx, a feature that distinguishes it from its sister species. The females have two mammae in the chest region, a simple uterus.

Marmosa robinsoni reproduces according to a simple schedule. It gives birth to 6 to 14 young after a gestation period of just 14 days. The tiny young, measuring only up to 12 millimeters, attach themselves to the mother's mammae where they may remain for around 30 days. Unlike many marsupials, female mouse opossums do not possess a pouch to protect the young as they develop.
|
|
Although equipped with three pairs of mammae, females have been observed to give birth about once a year to only a small number of young, commonly as few as one or two.Limnomys bryophilus at fieldmuseum.org, accessed 14 February 2012 The gray-bellied mountain rat is one of only two species in the genus Limnomys. The other, and the rat's only close relation, is the Mindanao mountain rat, Limnomys sibuanus.

On the forefeet, the third and fourth digits are longer than the second and fifth. Females lack a pouch and have 9 to 15 mammae. The tail looks naked to the unaided eye, but each scale in fact harbors three short hairs. Species of Cryptonanus and Gracilinanus are hardly distinguishable on external characters, though Cryptonanus species may have shorter tails, larger ears, broader eye-rings, and longer whiskers.

Foxes tend to have an average litter size of four to five with an 80 percent success rate in becoming pregnant. Litter sizes can vary greatly according to species and environmentthe Arctic fox, for example, can have up to eleven kits. The vixen usually has six or eight mammae. Each teat has 8 to 20 lactiferous ducts, which connect the mammary gland to the nipple, allowing for milk to be carried to the nipple.
|

Accessory breasts, also known as polymastia, supernumerary breasts, or mammae erraticae, is the condition of having an additional breast. Extra breasts may appear with or without nipples or areolae. It is a condition and a form of atavism which is most prevalent in male humans, and often goes untreated as it is mostly harmless. In recent years, many affected women have had a plastic surgery operation to remove the additional breasts, for purely aesthetic reasons.
|
|
Adult males are slightly larger and more muscular than females, and have wider heads and necks. Visual sex determination can, however, be difficult, since the penis and testes are located internally between the rectum and urinary bladder in males and females have a single pair of mammae near the armpits. Fertilization occurs by contact transfer without intromission, similar to some lizards. Polygynous mating usually results in a single offspring; twins are possible but rare.

Giant mouse lemurs have two pairs of mammae, one on the chest (pectoral) and one on the abdomen (abdominal). Their fur is typically grayish- brown on the dorsal (back) side and more gray in color on the ventral (front) side. The tail is typically black-tipped. The new population found by WWF in 2010 has an overall lighter color, along with reddish or rusty patches near the hands and feet on the dorsal side of the arms and legs.
|
|
Females have 0+2=4 mammae (no thoracic and two inguinal pairs), the same number as most other Australasian rodents. The earless water rat and Baiyankamys are related because they share the following characters: tail much longer than head-body length; soft, thick, greyish dorsal coat; long, narrow rostrum with a narrow top; very narrow canines; very narrow mesopterygoid fossae; narrow zygomatic arches with a high squamosal root. B. habbema also has the reduced external ears of the earless water rat.

Contrails may also produce lobes but these are incorrectly termed as mammatus. Mammatus may appear as smooth, ragged or lumpy lobes and may be opaque or translucent. Because mammatus occur as a grouping of lobes, the way they clump together can vary from an isolated cluster to a field of mammae that spread over hundreds of kilometers to being organized along a line, and may be composed of unequal or similarly-sized lobes. The individual mammatus lobe average diameters of and lengths on average of .

Females are able to reproduce from one-year-old or 425 g. Mating commences from late winter to early spring with a gestation period of 34 days. Rakali have four mammae with nipples located in the abdominal inguinal area enabling litters of an average of four to five are born from September to February and are suckled for four weeks. Sexual maturity develops at around twelve months but has been documented to commence at 4 months and breeding in the season of their birth.

The dorsal pelage is a grizzled olive-brown with scattered medium-length black guard hairs, and the underparts are whitish. The tail, which is a similar length to the body, is a uniform dark brown. The feet are broad, and the soles have fine ridges for climbing. It differs from Annandale's rat (Rattus annandalei) in having sleek fur with spines and fewer mammae, and from the ricefield rat (Rattus argentiventer) in having plain white underparts and lacking an orange spot in front of the ear.

The digits and metapodials (bones of the centers of the hand and feet) of the hands and feet are covered with dark hairs, but the ungual tufts at the bases of the claws consist of longer, gray hairs. The fifth digit of the foot is long, with the tip of its claw almost reaching the base of the claw of the fourth digit. The tail is dark and hardly furred, except for a pencil of long hairs at the end; some animals have a white tail tip. Females have six mammae.

Joeys have a continuous arch of cartilage in their shoulder girdle which disappears soon after birth; this supports the forelimbs, assisting the climb into the pouch. Young are completely contained in the pouch for 60 days after birth, wherein mammae provide nourishment during the remainder of development. Eyes first open around 80 days after birth, and young will leave the nest around 110 days after birth. By the time young are weaned, the thermoregulatory system is developed, and in conjunction with a large body size and thicker fur, they are able to regulate their own body temperature.

Pompeiian wall painting (Secret Museum, Naples) Latin words for "breasts" include mammae (cf. English "mammary"), papillae (more specifically for "nipples"), and ubera, breasts in their capacity to provide nourishment, including the teats or udder of an animal.Breasts are never ubera in Ovid's Amores, but are ubera throughout the Metamorphoses: at 3.31 (metaphorically); 4.324; 10.392; 9.358 (materna ... ubera, "motherly breasts"); 7.321 and 6.342 (lactantia ubera, "milk-producing breasts"); 15.117 and 472. Uber (singular) or ubera is used for animals by Ovid, Ars Amatoria 1.350 (the udder of a cow) and 2.375 (the teats of lactating dogs); by Horace, Sermones 1.1.110, Odes 2.19.10, 4.4.14 and 4.15.5, and elsewhere; by Tibullus, for sheep in 1.3.45; by Propertius, 2.34b.

Microryzomys species are small members of the rodent tribe Oryzomyini, weighing in the region of , and characterised by their long soft fur and tail longer than their head-and-body- length. They have small hind feet with six fleshy pads on the under surface, and with the fifth toe nearly as long as the middle three. The four pairs of mammae are arranged in the typical fashion for members of the tribe. At one time, this genus was considered to be a subgenus of Oryzomys, but Carleton and Musser (1989) raised it to full generic status on the basis of various anatomic details of skull and dentition and on certain morphological traits.

Bubalus skull Kidney of a Bubalus Smith described Bubalus as low in proportion to the bulk with very solid limbs, a small dewlap and a long, slender tail; the head is large with a strong convex-shaped narrow forehead, large eyes and funnel- shaped ears; horns are lying flat or bending laterally with a certain direction to the rear; the female udder has four mammae. Lydekker added that the line of back is nearly straight with 13 pairs of ribs; the tail is tufted and reaching about to the hocks; the horns are more or less markedly triangular for the greater part of their length and situated low down on the skull; the muzzle is broad, and the hair sparse in adults.

When Voss and Carleton formally characterized Oryzomyini two years later, they did place Pseudoryzomys in the group, even though it lacks complete mesoloph(id)s. The mesoloph is an accessory crest on the upper molars and the mesolophid is the corresponding structure on the lower molars. Only a few other animals now considered oryzomyines lack complete mesoloph(id)s, but they are absent in various non-oryzomyines, some of which had previously been regarded as close relatives of the oryzomyines that lack them. Oryzomyines with and without complete mesoloph(id)s share various other characters, however, including presence of mammae on the chest, absence of a gall bladder, and some characters of the skull, suggesting that they form one natural, monophyletic group.
